我想显示日期选择器弹出窗口。我找到了一些例子,但是我没有正确地得到它。我有一个edittext,我希望当我单击edittext时,应该弹出datepicker对话框,并且在设置日期之后,该日期应该以dd / mm / yyyy格式以edittext显示。请为我提供示例代码或良好的链接。

Answers:
在XML文件中尝试以下操作:
<EditText
android:id="@+id/Birthday"
custom:font="@string/font_avenir_book"
android:clickable="true"
android:editable="false"
android:hint="@string/birthday"/>
现在在Java文件中:
final Calendar myCalendar = Calendar.getInstance();
EditText edittext= (EditText) findViewById(R.id.Birthday);
DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel();
}
};
edittext.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
new DatePickerDialog(classname.this, date, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
});
现在,在上述活动中添加方法。
private void updateLabel() {
String myFormat = "MM/dd/yy"; //In which you need put here
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
edittext.setText(sdf.format(myCalendar.getTime()));
}
android:focusable="false"
在EditText的xml文件中添加以允许单触。
android:focusable="false"
andonclicklistner
android:longClickable="false"
。否则,用户可以在字段上调出粘贴选项(从而输入无效的日期)。
无法让这些工具中的任何一个工作,因此会添加我的一个,以防万一。
public class MyEditTextDatePicker implements OnClickListener, OnDateSetListener {
EditText _editText;
private int _day;
private int _month;
private int _birthYear;
private Context _context;
public MyEditTextDatePicker(Context context, int editTextViewID)
{
Activity act = (Activity)context;
this._editText = (EditText)act.findViewById(editTextViewID);
this._editText.setOnClickListener(this);
this._context = context;
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
_birthYear = year;
_month = monthOfYear;
_day = dayOfMonth;
updateDisplay();
}
@Override
public void onClick(View v) {
Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
DatePickerDialog dialog = new DatePickerDialog(_context, this,
calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
calendar.get(Calendar.DAY_OF_MONTH));
dialog.show();
}
// updates the date in the birth date EditText
private void updateDisplay() {
_editText.setText(new StringBuilder()
// Month is 0 based so add 1
.append(_day).append("/").append(_month + 1).append("/").append(_birthYear).append(" "));
}
}
还有一些其他人没有提到的东西。确保将以下内容放在EditText xml上。
android:focusable="false"
否则,就像我的情况一样,键盘会不断弹出。希望这可以帮助某人
class MyClass implements OnClickListener, OnDateSetListener {
EditText editText;
this.editText = (EditText) findViewById(R.id.editText);
this.editText.setOnClickListener(this);
@Override
public void onClick(View v) {
DatePickerDialog dialog = new DatePickerDialog(this, this, 2013, 2, 18);
dialog.show();
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// this.editText.setText();
}
}
还有另一种更好的可重用方法:
创建一个类:
class setDate implements OnFocusChangeListener, OnDateSetListener {
private EditText editText;
private Calendar myCalendar;
public setDate(EditText editText, Context ctx){
this.editText = editText;
this.editText.setOnFocusChangeListener(this);
myCalendar = Calendar.getInstance();
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// this.editText.setText();
String myFormat = "MMM dd, yyyy"; //In which you need put here
SimpleDateFormat sdformat = new SimpleDateFormat(myFormat, Locale.US);
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
editText.setText(sdformat.format(myCalendar.getTime()));
}
@Override
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
if(hasFocus){
new DatePickerDialog(ctx, this, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
}
}
然后在onCreate函数下调用此类:
EditText editTextFromDate = (EditText) findViewById(R.id.editTextFromDate);
setDate fromDate = new setDate(editTextFromDate, this);
class setDate implements View.OnFocusChangeListener, DatePickerDialog.OnDateSetListener {
?
<EditText
android:id="@+id/date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:hint="DD/MM/YYYY"
android:inputType="date"
android:focusable="false"/>
<EditText
android:id="@+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="00:00"
android:inputType="time"
android:focusable="false"/>
JAVA文件
import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.TimePicker;
import java.util.Calendar;
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
EditText selectDate,selectTime;
private int mYear, mMonth, mDay, mHour, mMinute;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
selectDate=(EditText)findViewById(R.id.date);
selectTime=(EditText)findViewById(R.id.time);
selectDate.setOnClickListener(this);
selectTime.setOnClickListener(this);
}
@Override
public void onClick(View view) {
if (view == selectDate) {
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(this,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
selectDate.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);
}
}, mYear, mMonth, mDay);
datePickerDialog.show();
}
if (view == selectTime) {
// Get Current Time
final Calendar c = Calendar.getInstance();
mHour = c.get(Calendar.HOUR_OF_DAY);
mMinute = c.get(Calendar.MINUTE);
// Launch Time Picker Dialog
TimePickerDialog timePickerDialog = new TimePickerDialog(this,
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay,
int minute) {
selectTime.setText(hourOfDay + ":" + minute);
}
}, mHour, mMinute, false);
timePickerDialog.show();
}
}
}
我就是这样做的:与选择的答案类似,但是使用静态对话框类,因此更可重用,并且还使用onFocusChange而不是onClick。
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
DialogFragment datePickerFragment = new DatePickerFragment() {
@Override
public void onDateSet(DatePicker view, int year, int month, int day) {
Log.d(TAG, "onDateSet");
Calendar c = Calendar.getInstance();
c.set(year, month, day);
editText.setText(df.format(c.getTime()));
nextField.requestFocus(); //moves the focus to something else after dialog is closed
}
};
datePickerFragment.show(getActivity().getSupportFragmentManager(), "datePicker");
}
}
});
和日期选择器对话框。
public static class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
@Override
public void onDateSet(DatePicker view, int year, int month, int day) {
//blah
}
}
所选答案对我来说不太有效,因为我必须先点击EditText框,然后在OnClickListener触发之前再次点击它。我可以通过用OnTouchListener替换OnClickListener来解决此问题,以防万一有人遇到类似问题,这就是我的代码:
Calendar myCalendar = Calendar.getInstance();
DatePickerDialog.OnDateSetListener date = new
DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel();
}
};
edittext.setOnTouchListener(new View.OnTouchListener() {
@Override
public void onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN) {
new DatePickerDialog(classname.this, date, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
}
});
private void updateLabel() {
String myFormat = "MM/dd/yy"; //In which you need put here
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
edittext.setText(sdf.format(myCalendar.getTime()));
}
#1。我想显示一个带有当前日期的日期选择器(已预先选择)(我使用黄油刀进行注射)
@OnClick(R.id.your_view) public void onClickYourView() {
final Calendar myCalendar = Calendar.getInstance();
DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// TODO Auto-generated method stub
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
String myFormat = "dd MMMM yyyy"; // your format
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.getDefault());
your_view.setText(sdf.format(myCalendar.getTime()));
}
};
new DatePickerDialog(mContext, date, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
new DatePickerDialog(mContext, date, 1990, 0, 1).show();
那么您可以使用myCalendar变量或直接在视图中获取文本。
使用片段,MvvmCross和Xamarin.Android的解决方案
public class EnterTimeView : MvxFragment, DatePickerDialog.IOnDateSetListener
{
private EditText datePickerText;
public EnterTimeView()
{
this.RetainInstance = true;
}
public override Android.Views.View OnCreateView(Android.Views.LayoutInflater inflater, Android.Views.ViewGroup container, Android.OS.Bundle savedInstanceState)
{
this.HasOptionsMenu = true;
var ignored = base.OnCreateView(inflater, container, savedInstanceState);
var view = inflater.Inflate(Resource.Layout.EnterTimeView, container, false);
datePickerText = view.FindViewById<EditText>(Resource.Id.DatePickerEditText);
datePickerText.Focusable = false;
datePickerText.Click += delegate
{
var dialog = new DatePickerDialogFragment(Activity, Convert.ToDateTime(datePickerText.Text), this);
dialog.Show(FragmentManager, "date");
};
var set = this.CreateBindingSet<EnterTimeView, EnterTimeViewModel>();
set.Bind(datePickerText).To(vm => vm.Date);
set.Apply();
return view;
}
public void OnDateSet(Android.Widget.DatePicker view, int year, int monthOfYear, int dayOfMonth)
{
datePickerText.Text = new DateTime(year, monthOfYear + 1, dayOfMonth).ToString();
}
private class DatePickerDialogFragment : Android.Support.V4.App.DialogFragment
{
private readonly Context _context;
private DateTime _date;
private readonly DatePickerDialog.IOnDateSetListener _listener;
public DatePickerDialogFragment(Context context, DateTime date, DatePickerDialog.IOnDateSetListener listener)
{
_context = context;
_date = date;
_listener = listener;
}
public override Dialog OnCreateDialog(Bundle savedState)
{
var dialog = new DatePickerDialog(_context, _listener, _date.Year, _date.Month - 1, _date.Day);
return dialog;
}
}
selectDate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DatePickerDialog mdiDialog =new DatePickerDialog(mContext,new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Toast.makeText(getApplicationContext(),year+ " "+monthOfYear+" "+dayOfMonth,Toast.LENGTH_LONG).show();
}
}, year, month, date);
mdiDialog.show();
}
});
我上课表演DatePicker
。我可以使用EditText
,TextView
或Button
import android.app.DatePickerDialog;
import android.content.Context;
import android.view.View;
import android.widget.DatePicker;
import android.widget.TextView;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.TimeZone;
public class TextViewDatePicker
implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
public static final String DATE_SERVER_PATTERN = "yyyy-MM-dd";
private DatePickerDialog mDatePickerDialog;
private TextView mView;
private Context mContext;
private long mMinDate;
private long mMaxDate;
public TextViewDatePicker(Context context, TextView view) {
this(context, view, 0, 0);
}
public TextViewDatePicker(Context context, TextView view, long minDate, long maxDate) {
mView = view;
mView.setOnClickListener(this);
mView.setFocusable(false);
mContext = context;
mMinDate = minDate;
mMaxDate = maxDate;
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, monthOfYear);
calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
Date date = calendar.getTime();
SimpleDateFormat formatter = new SimpleDateFormat(DATE_SERVER_PATTERN);
mView.setText(formatter.format(date));
}
@Override
public void onClick(View v) {
Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
mDatePickerDialog = new DatePickerDialog(mContext, this, calendar.get(Calendar.YEAR),
calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
if (mMinDate != 0) {
mDatePickerDialog.getDatePicker().setMinDate(mMinDate);
}
if (mMaxDate != 0) {
mDatePickerDialog.getDatePicker().setMaxDate(mMaxDate);
}
mDatePickerDialog.show();
}
public DatePickerDialog getDatePickerDialog() {
return mDatePickerDialog;
}
public void setMinDate(long minDate) {
mMinDate = minDate;
}
public void setMaxDate(long maxDate) {
mMaxDate = maxDate;
}
}
使用
EditText myEditText = findViewById(R.id.myEditText);
TextViewDatePicker editTextDatePicker = new TextViewDatePicker(context, myEditText, minDate, maxDate);
//TextViewDatePicker editTextDatePicker = new TextViewDatePicker(context, myEditText); //without min date, max date
使用数据绑定:
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:onClick="@{() -> viewModel.onDateEditTextClicked()}"
android:hint="@string/hint_date"
android:imeOptions="actionDone"
android:inputType="none"
android:maxLines="1"
android:text="@={viewModel.filterDate}" />
(见focusable
,inputType
和onClick
)
内部ViewModel:
public void onDateEditTextClicked() {
// do something
}
import android.app.DatePickerDialog;
import android.content.Context;
import android.view.View;
import android.widget.DatePicker;
import android.widget.TextView;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Locale;
public class DatePickerHelper {
private final Calendar calendar = Calendar.getInstance();
private final String dateFormat = "MM/dd/yy";
private TextView textView = null;
public DatePickerHelper(final Context context, TextView textView) {
this.textView = textView;
// Setup on click listener if the TextView is not null
if (textView != null) {
textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getDatePickerDialog(context).show();
}
});
}
}
/**
* Return a new date picker listener tied to the specified TextView field
* @return
*/
private DatePickerDialog.OnDateSetListener getOnDateSetListener() {
return new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, monthOfYear);
calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
SimpleDateFormat sdf = new SimpleDateFormat(dateFormat, Locale.US);
textView.setText(sdf.format(calendar.getTime()));
}
};
}
/**
* Return new DatePickerDialog for field
* @param context
* @return
*/
private DatePickerDialog getDatePickerDialog(Context context) {
return new DatePickerDialog(context, getOnDateSetListener(), calendar
.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
calendar.get(Calendar.DAY_OF_MONTH));
}
}
用法:
DatePickerHelper assessmentDueDateHelper = new DatePickerHelper(AssessmentsDetailActivity.this,
(TextView) findViewById(R.id.assessmentDueDateEditText));
使用这种简单的技术可以做到这一点:
第1步:创建片段对话框
public class DatePickerFragmentDialog extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(), (DatePickerDialog.OnDateSetListener) getActivity(), year, month, day);
}
}
步骤2:按照要求进行此操作
该活动必须实现:DatePickerDialog.OnDateSetListener
在按钮上设置onClickListener:
DialogFragment datePicker = new DatePickerFragmentDialog();
datePicker.show(getSupportFragmentManager(), "Custom Date Picker");
步骤3:覆写OnDateSetListener
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, month);
calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
@SuppressLint("SimpleDateFormat") DateFormat dateFormat = new
SimpleDateFormat("MM/dd/yyyy");
String currentDateString = dateFormat.format(calendar.getTime());
tvPaymentDate.setText(currentDateString);
}
因此,我们可以对日期使用任何格式:)
我尝试了所有建议的方法,但是它们都有自己的问题。
我认为最好的解决方案是使用如下所示的框架布局:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
.... />
<View
android:id="@+id/invisible_click_watcher"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true" />
</FrameLayout>
然后添加用@Android的答案精美编写的DatePickerDialog代码。
我认为最好重写EditText类...
public class EditTextDP extends android.support.v7.widget.AppCompatEditText implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
public EditTextDP(Context context) {
super(context);
setOnClickListener(this);
setFocusable(false);
}
public EditTextDP(Context context, AttributeSet attrs) {
super(context, attrs);
setOnClickListener(this);
setFocusable(false);
}
public EditTextDP(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
setOnClickListener(this);
setFocusable(false);
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
setText(new StringBuilder().append(dayOfMonth).append("/").append(monthOfYear + 1).append("/").append(year));
}
@Override
public void onClick(View v) {
Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
DatePickerDialog dialog = new DatePickerDialog(getContext(), this, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
dialog.show();
}
}
并在XML中使用它...
<*.*.*.EditTextDP
android:id="@+id/c1_dob_hm"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/round_edittext_white"
android:ems="10"
android:padding="8dp">
</*.*.*.EditTextDP>
editText1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DatePickerDialog.OnDateSetListener dpd = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
int s = monthOfYear + 1;
String a = dayOfMonth + "/" + s + "/" + year;
editText1.setText(a);
}
};
Time date = new Time();
DatePickerDialog d = new DatePickerDialog(UpdateStore.this, dpd, date.year, date.month, date.monthDay);
d.show();
}
});
用这个
your_edittext.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
final Calendar calendar = Calendar.getInstance();
int yy = calendar.get(Calendar.YEAR);
int mm = calendar.get(Calendar.MONTH);
int dd = calendar.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePicker = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
String date = String.valueOf(dayOfMonth) + "/" + String.valueOf(monthOfYear+1)
+ "/" + String.valueOf(year);
your_edittext.setText(date);
}
}, yy, mm, dd);
datePicker.show();
}
});
Kotlin端口,调用setDatePicker函数
private fun setDatePicker(dateEditText: EditText) {
val myCalendar = Calendar.getInstance()
val datePickerOnDataSetListener = DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
myCalendar.set(Calendar.YEAR, year)
myCalendar.set(Calendar.MONTH, monthOfYear)
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
updateLabel(myCalendar, dateEditText)
}
dateEditText.setOnClickListener {
DatePickerDialog(this@YourActivityName, datePickerOnDataSetListener, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show()
}
}
private fun updateLabel(myCalendar: Calendar, dateEditText: EditText) {
val myFormat: String = "dd-MMM-yyyy"
val sdf = SimpleDateFormat(myFormat, Locale.UK)
dateEditText.setText(sdf.format(myCalendar.time))
}
public class DatePickerActivity extends AppCompatActivity {
Button button;
static TextView textView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button= (Button) findViewById(R.id.btn_click);
textView= (TextView) findViewById(R.id.txt_date);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DialogFragment newFragment=new DatePickerFragment();
newFragment.show(getFragmentManager(), "datepicker");
}
});
}
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int day) {
String years=""+year;
String months=""+(monthOfYear+1);
String days=""+day;
if(monthOfYear>=0 && monthOfYear<9){
months="0"+(monthOfYear+1);
}
if(day>0 && day<10){
days="0"+day;
}
textView.setText(days+"/"+months+"/"+years);
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
//use the current date as the default date in the picker
final Calendar c=Calendar.getInstance();
int year=c.get(Calendar.YEAR);
int month=c.get(Calendar.MONTH);
int day=c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog=null;
datePickerDialog=new DatePickerDialog(getActivity(), this, year, month, day);
return datePickerDialog;
}
}
}
试试这个
btn=(Button)findViewById(R.id.chs);
final Dialog dialog = new Dialog(MainActivity.this);
dialog.setCanceledOnTouchOutside(true);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

dialog.show();
ok=(Button)dialog.findViewById(R.id.btn1);
ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
}
});
editText.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(final View v) {
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
final DatePickerDialog datePickerDialog = new DatePickerDialog(getContext(),
new DatePickerDialog.OnDateSetListener() {
String fmonth, fDate;
int month;
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
try {
if (monthOfYear < 10 && dayOfMonth < 10) {
fmonth = "0" + monthOfYear;
month = Integer.parseInt(fmonth) + 1;
fDate = "0" + dayOfMonth;
String paddedMonth = String.format("%02d", month);

} else {
fmonth = "0" + monthOfYear;
month = Integer.parseInt(fmonth) + 1;
String paddedMonth = String.format("%02d", month);
editText.setText(dayOfMonth + "/" + paddedMonth + "/" + year);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}, mYear, mMonth, mDay);
datePickerDialog.getDatePicker().setMaxDate(System.currentTimeMillis());
datePickerDialog.show();
}
});
日期选择器对话框
Calendar c=Calendar.getInstance();
Integer month=c.get(Calendar.MONTH);
Integer day=c.get(Calendar.DAY_OF_MONTH);
Integer year=c.get(Calendar.YEAR);
DatePickerDialog datePickerDialog =new DatePickerDialog(Expenture_Activity.this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
et_from.setText(dayOfMonth+"/"+month+"/"+year);
}
},year,month,day);
datePickerDialog.show();
试试这个:
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
DataPickerListener listener;
public DatePickerFragment(DataPickerListener l) {
listener = l;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the date picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(),
AlertDialog.THEME_HOLO_LIGHT, this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
month = month + 1;
String stringOfDate = day + "-" + month + "-" + year;
listener.setDate(stringOfDate);
Util.Log(stringOfDate);
}
@Override
public void onCancel(DialogInterface dialog) {
// TODO Auto-generated method stub
super.onCancel(dialog);
listener.cancel();
}
public static interface DataPickerListener {
void setDate(String date);
void cancel();
}

// use this function to open datePicker popup
DialogFragment newFragment;
public void pickDate() {
if (newFragment == null)
newFragment = new DatePickerFragment(new PickDateListener());
newFragment.show(getFragmentManager(), "Date Picker");
}
class PickDateListener implements DataPickerListener {
@Override
public void setDate(String date) {
createSpiner(date);
onetouch = false;
}
@Override
public void cancel() {
onetouch = false;
}
}
EditText text = (EditText) findViewById(R.id.editText);
text.setOnClickListener(new OnClickListener(){
@RequiresApi(api = Build.VERSION_CODES.N)
@Override
public void onClick(View view) {
DatePickerDialog datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker datePicker, int i, int i1, int i2) {
String date = i2 + "/" + (++i1) + "/" + i;
text.setText(date);
}
},year,month,date);
}
});
datePickerDialog.show();
您还可以通过这些语句设置最短日期和最长时间。
datepickerDialoge.getDatepicker().setMinDate(long Date);
datepickerDialoge.getDatepicker().setMaxDate(long Date);
注意:在datepickerDialog.show();之前添加这些行。声明您将在这样的日期2017年1月2日获得日期。
希望我的回答会有所帮助。
这对我来说是2020年1月
XML部分:
<EditText
android:id="@+id/etDOB"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:editable="false"
android:ems="10"
android:hint="Enter Your Date of Birth" />
Java部分:
final Calendar myCalendar = Calendar.getInstance();
userDOBView = (EditText)findViewById(R.id.etDOB);
final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener(){
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel();
}
};
userDOBView.setOnTouchListener(new View.OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event){
if(event.getAction() == MotionEvent.ACTION_DOWN){
new DatePickerDialog("YourClassName".this, date,
myCalendar.get(Calendar.YEAR),
myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
return true;
}
});
private void updateLabel() {
String myFormat = "MM/dd/yyyy"; //In which you need put here
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
// edittext.setText(sdf.format(myCalendar.getTime()));
userDOBView.setText(sdf.format(myCalendar.getTime()));
}
这是Kotlin扩展功能:
fun EditText.transformIntoDatePicker(context: Context, format: String, maxDate: Date? = null) {
isFocusableInTouchMode = false
isClickable = true
isFocusable = false
val myCalendar = Calendar.getInstance()
val datePickerOnDataSetListener =
DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
myCalendar.set(Calendar.YEAR, year)
myCalendar.set(Calendar.MONTH, monthOfYear)
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
val sdf = SimpleDateFormat(format, Locale.UK)
setText(sdf.format(myCalendar.time))
}
setOnClickListener {
DatePickerDialog(
context, datePickerOnDataSetListener, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)
).run {
maxDate?.time?.also { datePicker.maxDate = it }
show()
}
}
}
用法:
活动中:
editText.transformIntoDatePicker(this, "MM/dd/yyyy")
editText.transformIntoDatePicker(this, "MM/dd/yyyy", Date())
在片段中:
editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy")
editText.transformIntoDatePicker(requireContext(), "MM/dd/yyyy", Date())
我基于Linh的MvvmCross针对Xamarin.Android的解决方案:
public class DatePickerEditText : EditText, DatePickerDialog.IOnDateSetListener
{
IDisposable _clickSubscription;
public override bool Clickable => true;
protected DatePickerEditText(IntPtr javaReference, JniHandleOwnership transfer)
: base(javaReference, transfer)
=> Init();
public DatePickerEditText(Context context) : base(context)
=> Init();
public DatePickerEditText(Context context, IAttributeSet attrs)
: base(context, attrs)
=> Init();
public DatePickerEditText(Context context, IAttributeSet attrs, int defStyleAttr)
: base(context, attrs, defStyleAttr)
=> Init();
public DatePickerEditText(Context context, IAttributeSet attrs, int defStyleAttr, int defStyleRes)
: base(context, attrs, defStyleAttr, defStyleRes)
=> Init();
protected override void Dispose(bool disposing)
{
if (disposing)
{
_clickSubscription?.Dispose();
_clickSubscription = null;
}
base.Dispose(disposing);
}
public void OnDateSet(DatePicker view, int year, int month, int dayOfMonth)
=> Text = view.DateTime.ToString("d", CultureInfo.CurrentUICulture);
void Init()
{
SetFocusable(ViewFocusability.NotFocusable);
_clickSubscription = this.WeakSubscribe(nameof(Click), OnClick);
}
void OnClick(object sender, EventArgs e)
{
var date = DateTime.Today;
try
{
date = DateTime.Parse(Text, CultureInfo.CurrentUICulture);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex);
}
var dialog = new DatePickerDialog(Context,
this,
date.Year,
date.Month,
date.Day);
dialog.Show();
}
}
对于普通的Xamarin.Android版本,只需将WeakSubscribe替换为对EditText的Click事件的常规订阅,不要忘记在Dispose方法重写中取消订阅。
