下面的代码用于在AlertDialog中显示自定义列表

AlertDialog.Builder builderSingle = new AlertDialog.Builder(DialogActivity.this);
builderSingle.setIcon(R.drawable.ic_launcher);
builderSingle.setTitle("Select One Name:-");

final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(DialogActivity.this, android.R.layout.select_dialog_singlechoice);
arrayAdapter.add("Hardik");
arrayAdapter.add("Archit");
arrayAdapter.add("Jignesh");
arrayAdapter.add("Umang");
arrayAdapter.add("Gatti");

builderSingle.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });

builderSingle.setAdapter(arrayAdapter, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                String strName = arrayAdapter.getItem(which);
                AlertDialog.Builder builderInner = new AlertDialog.Builder(DialogActivity.this);
                builderInner.setMessage(strName);
                builderInner.setTitle("Your Selected Item is");
                builderInner.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog,int which) {
                                dialog.dismiss();
                            }
                        });
                builderInner.show();
            }
        });
builderSingle.show();

是否有可能检测到对该项目的长时间点击?我正在寻找可在所有api级别上使用的弹出菜单解决方案的时间

@Shvet应该是show()创建并显示对话框,而create()仅创建对话框。
htafoya 2015年

如何使用此设置,而不是对列表进行硬编码,我需要从用户已经拥有的解析中获取一些数据。
stanley santoso 2015年

@stanleysantoso创建您自己的适配器,将其填充数据,然后将其设置为alertdialog的适配器:dialogBu​​ilder.setAdapter(MyCustomAdapter); 那应该起作用

select_dialog_single_choice的布局是什么?

根据文档,可以将三种列表用于AlertDialog

  1. 传统单选清单
  2. 永久单选列表(单选按钮)
  3. 永久性多项选择列表(复选框)

我将在下面给出每个示例。

传统单选清单

制作传统的单项选择列表的方法是使用setItems

在此处输入图片说明

Java版本

// setup the alert builder
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Choose an animal");

// add a list
String[] animals = {"horse", "cow", "camel", "sheep", "goat"};
builder.setItems(animals, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        switch (which) {
            case 0: // horse
            case 1: // cow
            case 2: // camel
            case 3: // sheep
            case 4: // goat
        }
    }
});

// create and show the alert dialog
AlertDialog dialog = builder.create();
dialog.show();

不需要OK按钮,因为一旦用户单击列表项,控件就会返回到OnClickListener

Kotlin版本

// setup the alert builder
val builder = AlertDialog.Builder(context)
builder.setTitle("Choose an animal")

// add a list
val animals = arrayOf("horse", "cow", "camel", "sheep", "goat")
builder.setItems(animals) { dialog, which ->
    when (which) {
        0 -> { /* horse */ }
        1 -> { /* cow   */ }
        2 -> { /* camel */ }
        3 -> { /* sheep */ }
        4 -> { /* goat  */ }
    }
}

// create and show the alert dialog
val dialog = builder.create()
dialog.show()

单选按钮列表

在此处输入图片说明

单选按钮列表相对于传统列表的优势在于,用户可以看到当前设置。制作单选按钮列表的方法是使用setSingleChoiceItems

Java版本

// setup the alert builder
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Choose an animal");

// add a radio button list
String[] animals = {"horse", "cow", "camel", "sheep", "goat"};
int checkedItem = 1; // cow
builder.setSingleChoiceItems(animals, checkedItem, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // user checked an item
    }
});

// add OK and Cancel buttons
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // user clicked OK
    }
});
builder.setNegativeButton("Cancel", null);

// create and show the alert dialog
AlertDialog dialog = builder.create();
dialog.show();

我在此处对所选项目进行了硬编码,但是您可以在实际项目中使用类成员变量来跟踪它。

Kotlin版本

// setup the alert builder
val builder = AlertDialog.Builder(context)
builder.setTitle("Choose an animal")

// add a radio button list
val animals = arrayOf("horse", "cow", "camel", "sheep", "goat")
val checkedItem = 1 // cow
builder.setSingleChoiceItems(animals, checkedItem) { dialog, which ->
    // user checked an item
}


// add OK and Cancel buttons
builder.setPositiveButton("OK") { dialog, which ->
    // user clicked OK
}
builder.setNegativeButton("Cancel", null)

// create and show the alert dialog
val dialog = builder.create()
dialog.show()

复选框清单

在此处输入图片说明

制作复选框列表的方法是使用setMultiChoiceItems

Java版本

// setup the alert builder
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Choose some animals");

// add a checkbox list
String[] animals = {"horse", "cow", "camel", "sheep", "goat"};
boolean[] checkedItems = {true, false, false, true, false};
builder.setMultiChoiceItems(animals, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which, boolean isChecked) {
        // user checked or unchecked a box
    }
});

// add OK and Cancel buttons
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        // user clicked OK
    }
});
builder.setNegativeButton("Cancel", null);

// create and show the alert dialog
AlertDialog dialog = builder.create();
dialog.show();

在这里,我对列表中的哪些项目进行了硬编码。您更可能希望在一个目录中跟踪它们ArrayList<Integer>。有关更多详细信息,请参见文档示例。您也可以将选中的项目设置为:null如果您始终希望所有内容都以不选中状态开始。

Kotlin版本

// setup the alert builder
val builder = AlertDialog.Builder(context)
builder.setTitle("Choose some animals")

// add a checkbox list
val animals = arrayOf("horse", "cow", "camel", "sheep", "goat")
val checkedItems = booleanArrayOf(true, false, false, true, false)
builder.setMultiChoiceItems(animals, checkedItems) { dialog, which, isChecked ->
    // user checked or unchecked a box
}

// add OK and Cancel buttons
builder.setPositiveButton("OK") { dialog, which ->
    // user clicked OK
}
builder.setNegativeButton("Cancel", null)

// create and show the alert dialog
val dialog = builder.create()
dialog.show()

笔记

  • 对于context以上代码中的,请不要使用,getApplicationContext()否则您会得到一个IllegalStateException(有关原因,请参见此处)。而是获取对活动上下文的引用,例如使用this
  • 您也可以使用setAdaptersetCursor或将CursorListAdapter传入setSingleChoiceItems或来从数据库或其他来源填充​​列表项setMultiChoiceItems
  • 如果列表的长度超过了屏幕上的显示范围,则对话框将自动滚动列表。但是,如果您的清单很长,我想您应该使用RecyclerView进行自定义对话框
  • 为了测试上面的所有示例,我只有一个带有单个按钮的简单项目,而不是单击该对话框时显示的对话框:

    import android.support.v7.app.AppCompatActivity;
    
    public class MainActivity extends AppCompatActivity {
    
        Context context;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            context = this;
        }
    
        public void showAlertDialogButtonClicked(View view) {
    
            // example code to create alert dialog lists goes here
        }
    }

如果要使用自定义适配器实现简单列表(1),请在侦听器中使用Builder.setAdapter(ListAdapter, DialogInterface.OnClickListener):等于单击的项目位置。将无效。whichonClickBuilder.setOnItemSelectedListener
Miha_x64 '18

您可以使用自定义对话框。

自定义对话框的布局。 list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
    <ListView
        android:id="@+id/lv"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"/>
</LinearLayout>

在您的活动中

Dialog dialog = new Dialog(Activity.this);
       dialog.setContentView(R.layout.list)

ListView lv = (ListView ) dialog.findViewById(R.id.lv);
dialog.setCancelable(true);
dialog.setTitle("ListView");
dialog.show();

编辑:

使用alertdialog

String names[] ={"A","B","C","D"};
AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
LayoutInflater inflater = getLayoutInflater();
View convertView = (View) inflater.inflate(R.layout.custom, null);
alertDialog.setView(convertView);
alertDialog.setTitle("List");
ListView lv = (ListView) convertView.findViewById(R.id.lv);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,names);
lv.setAdapter(adapter);
alertDialog.show();

custom.xml

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/listView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

</ListView>

@ArhatBaid但是,当我在setMessage中放置一条消息时,setItems无法正常工作。我在Google中搜索,但找到的答案是在setTitle中设置消息。但是问题是setTitle只允许几个字符。有没有一种方法可以在警报对话框中使用setMessage和setItems?

@David,您必须进行自定义对话框。

这个解决方案非常好,因为您也可以使用ListAdapterwith setSingleChoiceItems(非常类似于上面的调用)

使用“ import android.app.AlertDialog;”导入,然后编写

    String[] items = {"...","...."};             
    AlertDialog.Builder build = new AlertDialog.Builder(context);
    build.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            //do stuff....
        }
    }).create().show();

您需要使用bc创建,然后构建AlertDialog,然后显示此内容。不是建造者。(c)Facebamm
Facebamm

@Facebamm不是真的。show()两者都做。Calling this method is functionally identical to: AlertDialog dialog = builder.create(); dialog.show();这是直接从show()方法的文档
ᴛʜᴇᴘᴀᴛᴇʟ

是的,但是有时我会看到一些明显的用户界面错误。(c)Facebamm
Facebamm

不,那不是真的。show()与create()。show()相同;/ ** *使用提供给此*构建器的参数创建一个{@link AlertDialog},并立即显示该对话框。* <p> *调用此方法在功能上等同于:* <pre> * AlertDialog对话框= builder.create(); * dialog.show(); * </ pre> * / public AlertDialog show(){最终的AlertDialog对话框= create(); dialog.show(); 返回对话框;}

好的,我已经测试了一段时间,我说很抱歉,没错。(c)Facebamm

这太简单了

final CharSequence[] items = {"Take Photo", "Choose from Library", "Cancel"};

AlertDialog.Builder builder = new AlertDialog.Builder(MyProfile.this);

builder.setTitle("Add Photo!");
builder.setItems(items, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int item) {
        if (items[item].equals("Take Photo")) {
            getCapturesProfilePicFromCamera();
        } else if (items[item].equals("Choose from Library")) {
            getProfilePicFromGallery();
        } else if (items[item].equals("Cancel")) {
            dialog.dismiss();
        }
    }
});
builder.show();

在科特林:

fun showListDialog(context: Context){
    // setup alert builder
    val builder = AlertDialog.Builder(context)
    builder.setTitle("Choose an Item")

    // add list items
    val listItems = arrayOf("Item 0","Item 1","Item 2")
    builder.setItems(listItems) { dialog, which ->
        when (which) {
            0 ->{
                Toast.makeText(context,"You Clicked Item 0",Toast.LENGTH_LONG).show()
                dialog.dismiss()
            }
            1->{
                Toast.makeText(context,"You Clicked Item 1",Toast.LENGTH_LONG).show()
                dialog.dismiss()
            }
            2->{

                dialog.dismiss()

这是显示带有自定义列表项的自定义布局对话框的方法,可以根据您的要求进行自定义。

在此处输入图片说明

步骤-1创建对话框的布局,即:-

R.layout.assignment_dialog_list_view

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/rectangle_round_corner_assignment_alert"
    android:orientation="vertical">
    <TextView
        android:id="@+id/tv_popup_title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="8dp"
        android:singleLine="true"
        android:paddingStart="4dp"
        android:text="View as:"
        android:textColor="#4f4f4f" />

    <ListView
        android:id="@+id/lv_assignment_users"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />
</LinearLayout>

步骤-2根据您的业务逻辑创建自定义列表项布局

R.layout.item_assignment_dialog_list_layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:padding="4dp"
    android:orientation="horizontal">
    <ImageView
        android:id="@+id/iv_user_profile_image"
        android:visibility="visible"
        android:layout_width="42dp"
        android:layout_height="42dp" />
    <TextView
        android:id="@+id/tv_user_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="8dp"
        android:layout_marginStart="8dp"
        android:paddingBottom="8dp"
        android:textColor="#666666"
        android:textSize="18sp"
        tools:text="ABCD XYZ" />
</LinearLayout>

步骤-3创建您自己选择的数据模型类

public class AssignmentUserModel {

private String userId;
private String userName;
private String userRole;
private Bitmap userProfileBitmap;

public AssignmentUserModel(String userId, String userName, String userRole, Bitmap userProfileBitmap) {
    this.userId = userId;
    this.userName = userName;
    this.userRole = userRole;
    this.userProfileBitmap = userProfileBitmap;
}


public String getUserId() {
    return userId;
}

public void setUserId(String userId) {
    this.userId = userId;
}

public String getUserName() {
    return userName;
}

public void setUserName(String userName) {
    this.userName = userName;
}

public String getUserRole() {
    return userRole;
}

public void setUserRole(String userRole) {
    this.userRole = userRole;
}

public Bitmap getUserProfileBitmap() {
    return userProfileBitmap;
}

public void setUserProfileBitmap(Bitmap userProfileBitmap) {
    this.userProfileBitmap = userProfileBitmap;
}

}

步骤-4创建自定义适配器

public class UserListAdapter extends ArrayAdapter<AssignmentUserModel> {
private final Context context;
private final List<AssignmentUserModel> userList;

public UserListAdapter(@NonNull Context context, int resource, @NonNull List<AssignmentUserModel> objects) {
    super(context, resource, objects);
    userList = objects;
    this.context = context;
 }

@SuppressLint("ViewHolder")
@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View rowView = inflater.inflate(R.layout.item_assignment_dialog_list_layout, parent, false);
    ImageView profilePic = rowView.findViewById(R.id.iv_user_profile_image);
    TextView userName = rowView.findViewById(R.id.tv_user_name);
    AssignmentUserModel user = userList.get(position);

    userName.setText(user.getUserName());

    Bitmap bitmap = user.getUserProfileBitmap();

    profilePic.setImageDrawable(bitmap);

    return rowView;
}

}

步骤-5创建此函数并在此方法中提供上述数据模型的ArrayList

// Pass list of your model as arraylist
private void showCustomAlertDialogBoxForUserList(ArrayList<AssignmentUserModel> allUsersList) {
        final Dialog dialog = new Dialog(mActivity);
        dialog.setContentView(R.layout.assignment_dialog_list_view);
        if (dialog.getWindow() != null) {
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); // this is optional
        }
        ListView listView = dialog.findViewById(R.id.lv_assignment_users);
        TextView tv = dialog.findViewById(R.id.tv_popup_title);
        ArrayAdapter arrayAdapter = new UserListAdapter(context, R.layout.item_assignment_dialog_list_layout, allUsersList);
        listView.setAdapter(arrayAdapter);
        listView.setOnItemClickListener((adapterView, view, which, l) -> {
            Log.d(TAG, "showAssignmentsList: " + allUsersList.get(which).getUserId());
           // TODO : Listen to click callbacks at the position
        });
        dialog.show();
    }

步骤-6将圆角背景赋予对话框

@ drawable / rectangle_round_corner_assignment_alert

    <?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#ffffffff" />
    <corners android:radius="16dp" />
    <padding
        android:bottom="16dp"
        android:left="16dp"
        android:right="16dp"
        android:top="16dp" />
</shape>

在AlertDialog中创建EditText单元后,使方法被调用更通用吗?

public static void EditTextListPicker(final Activity activity, final EditText EditTextItem, final String SelectTitle, final String[] SelectList) {
    EditTextItem.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            AlertDialog.Builder builder = new AlertDialog.Builder(activity);
            builder.setTitle(SelectTitle);
            builder.setItems(SelectList, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialogInterface, int item) {
                    EditTextItem.setText(SelectList[item]);
                }
            });
            builder.create().show();
            return false;
        }
    });
}

private void AlertDialogue(final List<Animals> animals) {
 final AlertDialog.Builder alertDialog = new AlertDialog.Builder(AdminActivity.this);
 alertDialog.setTitle("Filter by tag");

 final String[] animalsArray = new String[animals.size()];

 for (int i = 0; i < tags.size(); i++) {
  animalsArray[i] = tags.get(i).getanimal();

 }

 final int checkedItem = 0;
 alertDialog.setSingleChoiceItems(animalsArray, checkedItem, new DialogInterface.OnClickListener() {
  @Override
  public void onClick(DialogInterface dialog, int which) {

   Log.e(TAG, "onClick: " + animalsArray[which]);

  }
 });


 AlertDialog alert = alertDialog.create();
 alert.setCanceledOnTouchOutside(false);
 alert.show();

}

尽管此代码可以回答问题,但提供有关如何和/或为什么解决问题的其他上下文将提高​​答案的长期价值。
