Android中是否有一种方法可以检测屏幕上是否显示软件（又名“软”）键盘？

没有直接的方法-请参阅http://groups.google.com/group/android-platform/browse_thread/thread/1728f26f2334c060/5e4910f0d9eb898a来自Android团队的Dianne Hackborn的答复。但是，您可以通过检查#onMeasure中的窗口大小是否更改来间接检测到它。请参阅如何检查Android中软件键盘的可见性？。

这对我有用。也许这始终是所有版本的最佳方法。

设置键盘可见性的属性并观察此更改是有效的，因为onGlobalLayout方法会多次调用。另外，检查设备的旋转情况也不错，而windowSoftInputMode不是adjustNothing。

boolean isKeyboardShowing = false;
void onKeyboardVisibilityChanged(boolean opened) {
    print("keyboard " + opened);
}

// ContentView is the root view of the layout of this activity/fragment    
contentView.getViewTreeObserver().addOnGlobalLayoutListener(
    new ViewTreeObserver.OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {

        Rect r = new Rect();
        contentView.getWindowVisibleDisplayFrame(r);
        int screenHeight = contentView.getRootView().getHeight();

        // r.bottom is the position above soft keypad or device button.
        // if keypad is shown, the r.bottom is smaller than that before.
        int keypadHeight = screenHeight - r.bottom;

        Log.d(TAG, "keypadHeight = " + keypadHeight);

        if (keypadHeight > screenHeight * 0.15) { // 0.15 ratio is perhaps enough to determine keypad height.
            // keyboard is opened
            if (!isKeyboardShowing) {
                isKeyboardShowing = true
                onKeyboardVisibilityChanged(true)
            }
        }
        else {
            // keyboard is closed
            if (isKeyboardShowing) {
                isKeyboardShowing = false
                onKeyboardVisibilityChanged(false)
            }
        }
    }
});

试试这个：

InputMethodManager imm = (InputMethodManager) getActivity()
            .getSystemService(Context.INPUT_METHOD_SERVICE);

    if (imm.isAcceptingText()) {
        writeToLog("Software Keyboard was shown");
    } else {
        writeToLog("Software Keyboard was not shown");
    }

我创建了一个可用于此目的的简单类：https : //github.com/ravindu1024/android-keyboardlistener。只需将其复制到您的项目中并按以下方式使用：

KeyboardUtils.addKeyboardToggleListener(this, new KeyboardUtils.SoftKeyboardToggleListener()
{
    @Override
    public void onToggleSoftKeyboard(boolean isVisible)
    {
        Log.d("keyboard", "keyboard visible: "+isVisible);
    }
});

好简单

1.在您的根视图上放置id

rootView在这种情况下只是一个指向我的根视图的视图relative layout：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:id="@+id/addresses_confirm_root_view"
                android:background="@color/WHITE_CLR">

2.在活动中初始化您的根视图：

RelativeLayout rootView = (RelativeLayout) findViewById(R.id.addresses_confirm_root_view);

3.通过使用检测键盘是打开还是关闭 getViewTreeObserver()

    rootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                int heightDiff = rootView.getRootView().getHeight() - rootView.getHeight();

                if (heightDiff > 100) { 
                    Log.e("MyActivity", "keyboard opened");
                } else { 
                    Log.e("MyActivity", "keyboard closed");
                }
            }
        });

我以此为基础：http : //www.ninthavenue.com.au/how-to-check-if-the-software-keyboard-is-shown-in-android

/**
* To capture the result of IMM hide/show soft keyboard
*/
public class IMMResult extends ResultReceiver {
     public int result = -1;
     public IMMResult() {
         super(null);
}

@Override 
public void onReceiveResult(int r, Bundle data) {
    result = r;
}

// poll result value for up to 500 milliseconds
public int getResult() {
    try {
        int sleep = 0;
        while (result == -1 && sleep < 500) {
            Thread.sleep(100);
            sleep += 100;
        }
    } catch (InterruptedException e) {
        Log.e("IMMResult", e.getMessage());
    }
    return result;
}
}

然后写了这个方法：

public boolean isSoftKeyboardShown(InputMethodManager imm, View v) {

    IMMResult result = new IMMResult();
    int res;

    imm.showSoftInput(v, 0, result);

    // if keyboard doesn't change, handle the keypress
    res = result.getResult();
    if (res == InputMethodManager.RESULT_UNCHANGED_SHOWN ||
            res == InputMethodManager.RESULT_UNCHANGED_HIDDEN) {

        return true;
    }
    else
        return false;

}

然后，您可以使用它来测试可能已打开软键盘的所有字段（EditText，AutoCompleteTextView等）：

    InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
    if(isSoftKeyboardShown(imm, editText1) | isSoftKeyboardShown(imm, autocompletetextview1))
        //close the softkeyboard
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

绝对不是理想的解决方案，但是它可以完成工作。

您可以使用showSoftInput（）和hideSoftInput（）的回调结果来检查键盘的状态。完整的详细信息和示例代码位于

http://www.ninthavenue.com.au/how-to-check-if-the-software-keyboard-is-shown-in-android

您可以参考此答案-https: //stackoverflow.com/a/24105062/3629912

每次都对我有用。

adb shell dumpsys window InputMethod | grep "mHasSurface"

如果软件键盘可见，它将返回true。

因此，在长时间使用AccessibilityServices，窗口插图，屏幕高度检测等之后，我想我找到了一种方法。

免责声明：它在Android中使用隐藏方法，这意味着可能不一致。但是，在我的测试中，它似乎有效。

该方法是InputMethodManager＃getInputMethodWindowVisibleHeight（），并且从Lollipop（5.0）开始就存在。

调用将返回当前键盘的高度（以像素为单位）。从理论上讲，键盘的高度不应为0像素，因此我做了一个简单的高度检查（在Kotlin中）：

val imm by lazy { context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager }
if (imm.inputMethodWindowVisibleHeight > 0) {
    //keyboard is shown
else {
    //keyboard is hidden
}

当我调用隐藏方法时，我使用Android Hidden API来避免反射（我为我开发的应用程序做了很多事情，大多数是hacky / tuner应用程序），但是反射也应该可行：

val imm by lazy { context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager }
val windowHeightMethod = InputMethodManager::class.java.getMethod("getInputMethodWindowVisibleHeight")
val height = windowHeightMethod.invoke(imm) as Int
//use the height val in your logic

对于我所需的需求来说，这要简​​单得多。希望这会有所帮助：

在MainActivity上：

public void dismissKeyboard(){
    InputMethodManager imm =(InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(mSearchBox.getWindowToken(), 0);
    mKeyboardStatus = false;
}

public void showKeyboard(){
    InputMethodManager imm =(InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
    mKeyboardStatus = true;
}

private boolean isKeyboardActive(){
    return mKeyboardStatus;
}

mKeyboardStatus的默认基本布尔值将初始化为false。

然后按如下所示检查值，并在必要时执行操作：

 mSearchBox.requestFocus();
    if(!isKeyboardActive()){
        showKeyboard();
    }else{
        dismissKeyboard();
    }

如果您需要检查键盘状态，这应该可以工作：

fun Activity.isKeyboardOpened(): Boolean {
    val r = Rect()

    val activityRoot = getActivityRoot()
    val visibleThreshold = dip(UiUtils.KEYBOARD_VISIBLE_THRESHOLD_DP)

    activityRoot.getWindowVisibleDisplayFrame(r)

    val heightDiff = activityRoot.rootView.height - r.height()

    return heightDiff > visibleThreshold;
}

fun Activity.getActivityRoot(): View {
    return (findViewById<ViewGroup>(android.R.id.content)).getChildAt(0);
}

其中UiUtils.KEYBOARD_VISIBLE_THRESHOLD_DP= 100和dip（）是转换dpToPx的anko函数：

fun dip(value: Int): Int {
    return (value * Resources.getSystem().displayMetrics.density).toInt()
}

我通过设置GlobalLayoutListener来做到这一点，如下所示：

final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(
        new OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                int heightView = activityRootView.getHeight();
                int widthView = activityRootView.getWidth();
                if (1.0 * widthView / heightView > 3) {
                    //Make changes for Keyboard not visible
                } else {
                    //Make changes for keyboard visible
                }
            }
        });

尝试这段代码，如果显示了KeyboardShown，那么它确实起作用，然后此函数返回true值...。

private final String TAG = "TextEditor";
private TextView mTextEditor;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_editor);
    mTextEditor = (TextView) findViewById(R.id.text_editor);
    mTextEditor.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            isKeyboardShown(mTextEditor.getRootView());
        }
    });
}

private boolean isKeyboardShown(View rootView) {
    /* 128dp = 32dp * 4, minimum button height 32dp and generic 4 rows soft keyboard */
    final int SOFT_KEYBOARD_HEIGHT_DP_THRESHOLD = 128;

    Rect r = new Rect();
    rootView.getWindowVisibleDisplayFrame(r);
    DisplayMetrics dm = rootView.getResources().getDisplayMetrics();
    /* heightDiff = rootView height - status bar height (r.top) - visible frame height (r.bottom - r.top) */
    int heightDiff = rootView.getBottom() - r.bottom;
    /* Threshold size: dp to pixels, multiply with display density */
    boolean isKeyboardShown = heightDiff > SOFT_KEYBOARD_HEIGHT_DP_THRESHOLD * dm.density;

    Log.d(TAG, "isKeyboardShown ? " + isKeyboardShown + ", heightDiff:" + heightDiff + ", density:" + dm.density
            + "root view height:" + rootView.getHeight() + ", rect:" + r);

    return isKeyboardShown;
}

就我而言，我只有一个人EditText可以管理布局，因此我提出了这个解决方案。它运作良好，基本上是一个自定义项EditText，可以在焦点发生变化或按下后退/完成按钮时侦听焦点并发送本地广播。为了工作，您需要View使用android:focusable="true"和在布局中放置一个虚拟对象，android:focusableInTouchMode="true"因为调用时clearFocus()焦点将重新分配给第一个可聚焦视图。虚拟视图的示例：

<View
android:layout_width="1dp"
android:layout_height="1dp"
android:focusable="true"
android:focusableInTouchMode="true"/>

其他资讯

用于检测布局更改差异的解决方案效果不佳，因为它很大程度上取决于屏幕密度，因为在某些设备中100px可能很大，而在其他某些设备中则没有，您可能会得到误报。另外，不同的供应商具有不同的键盘。

在Android中，您可以通过ADB Shell进行检测。我编写并使用了这种方法：

{
        JSch jsch = new JSch();
        try {
            Session session = jsch.getSession("<userName>", "<IP>", 22);
            session.setPassword("<Password>");
            Properties config = new Properties();
            config.put("StrictHostKeyChecking", "no");
            session.setConfig(config);
            session.connect();

            ChannelExec channel = (ChannelExec)session.openChannel("exec");
            BufferedReader in = new BufferedReader(new    
            InputStreamReader(channel.getInputStream()));
            channel.setCommand("C:/Android/android-sdk/platform-tools/adb shell dumpsys window 
            InputMethod | findstr \"mHasSurface\"");
            channel.connect();

            String msg = null;
            String msg2 = " mHasSurface=true";

            while ((msg = in.readLine()) != null) {
                Boolean isContain = msg.contains(msg2);
                log.info(isContain);
                if (isContain){
                    log.info("Hiding keyboard...");
                    driver.hideKeyboard();
                }
                else {
                    log.info("No need to hide keyboard.");
                }
            }

            channel.disconnect();
            session.disconnect();

        } catch (JSchException | IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

final View activityRootView = findViewById(R.id.rootlayout);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {

            Rect r = new Rect();
            activityRootView.getWindowVisibleDisplayFrame(r);

            int screenHeight = activityRootView.getRootView().getHeight();
            Log.e("screenHeight", String.valueOf(screenHeight));
            int heightDiff = screenHeight - (r.bottom - r.top);
            Log.e("heightDiff", String.valueOf(heightDiff));
            boolean visible = heightDiff > screenHeight / 3;
            Log.e("visible", String.valueOf(visible));
            if (visible) {
                Toast.makeText(LabRegister.this, "I am here 1", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(LabRegister.this, "I am here 2", Toast.LENGTH_SHORT).show();
            }
        }
});

@iWantScala的答案很好，但对我不起作用
rootView.getRootView().getHeight()总是具有相同的价值

一种方法是定义两个变量

private int maxRootViewHeight = 0;
private int currentRootViewHeight = 0;

添加全局侦听器

rootView.getViewTreeObserver()
    .addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            currentRootViewHeight = rootView.getHeight();
            if (currentRootViewHeight > maxRootViewHeight) {
                maxRootViewHeight = currentRootViewHeight;
            }
        }
    });

然后检查

if (currentRootViewHeight >= maxRootViewHeight) {
    // Keyboard is hidden
} else {
    // Keyboard is shown
}

工作良好

现在终于有了直接的途径，从基于Kotlin的Android R开始。

 val imeInsets = view.rootWindowInsets.getInsets(Type.ime()) 
    if (imeInsets.isVisible) { 
     //Ime is visible
     //Lets move our view by the height of the IME
     view.translationX = imeInsets.bottom }

我有一个类似的问题。我需要对屏幕上的Enter键（隐藏键盘）做出反应。在这种情况下，您可以订阅打开了键盘的文本视图的OnEditorAction-如果您有多个可编辑的框，请订阅所有这些。

在“活动”中，您可以完全控制键盘，因此，如果您侦听所有打开和关闭事件，无论您是否打开键盘，都不会遇到任何问题。

有一个直接的方法可以找到答案。而且，它不需要更改布局。
因此，它也可以在沉浸式全屏模式下工作。
但是，不幸的是，它不适用于所有设备。因此，您必须使用您的设备进行测试。

诀窍是您尝试隐藏或显示软键盘并捕获该尝试的结果。
如果工作正常，则说明键盘没有真正显示或隐藏。我们只是要求状态。

为了保持最新状态，您只需使用Handler即可重复此操作，例如每200毫秒重复一次。

下面的实现仅进行一次检查。
如果进行多次检查，则应启用所有（_keyboardVisible）测试。

public interface OnKeyboardShowHide
{
    void    onShowKeyboard( Object param );
    void    onHideKeyboard( Object param );
}

private static Handler      _keyboardHandler    = new Handler();
private boolean             _keyboardVisible    = false;
private OnKeyboardShowHide  _keyboardCallback;
private Object              _keyboardCallbackParam;

public void start( OnKeyboardShowHide callback, Object callbackParam )
{
    _keyboardCallback      = callback;
    _keyboardCallbackParam = callbackParam;
    //
    View view = getCurrentFocus();
    if (view != null)
    {
        InputMethodManager imm = (InputMethodManager) getSystemService( Activity.INPUT_METHOD_SERVICE );
        imm.hideSoftInputFromWindow( view.getWindowToken(), InputMethodManager.HIDE_IMPLICIT_ONLY, _keyboardResultReceiver );
        imm.showSoftInput( view, InputMethodManager.SHOW_IMPLICIT, _keyboardResultReceiver );
    }
    else // if (_keyboardVisible)
    {
        _keyboardVisible = false;
        _keyboardCallback.onHideKeyboard( _keyboardCallbackParam );
    }
}

private ResultReceiver      _keyboardResultReceiver = new ResultReceiver( _keyboardHandler )
{
    @Override
    protected void onReceiveResult( int resultCode, Bundle resultData )
    {
        switch (resultCode)
        {
            case InputMethodManager.RESULT_SHOWN :
            case InputMethodManager.RESULT_UNCHANGED_SHOWN :
                // if (!_keyboardVisible)
                {
                    _keyboardVisible = true;
                    _keyboardCallback.onShowKeyboard( _keyboardCallbackParam );
                }
                break;
            case InputMethodManager.RESULT_HIDDEN :
            case InputMethodManager.RESULT_UNCHANGED_HIDDEN :
                // if (_keyboardVisible)
                {
                    _keyboardVisible = false;
                    _keyboardCallback.onHideKeyboard( _keyboardCallbackParam );
                }
                break;
        }
    }
};

这是一种解决方法，可以了解软键盘是否可见。

1. 使用ActivityManager.getRunningServices（max_count_of_services）;检查系统上正在运行的服务。
2. 从返回的ActivityManager.RunningServiceInfo实例中，检查clientCount值以获取软键盘服务。
3. 每当显示上述软键盘时，上述clientCount都会增加。例如，如果clientCount最初为1，则显示键盘时为2。
4. 在关闭键盘时，clientCount会减少。在这种情况下，它将重置为1。

一些流行的键盘在其className中具有某些关键字：

1. Google AOSP = IME
2. Swype = IME
3. 快捷键= KeyboardService
4. Fleksy =键盘
5. Adaptxt = IME（KPTAdaptxtIME）
6. 智能=键盘（SmartKeyboard）

在ActivityManager.RunningServiceInfo中，检查ClassNames中的上述模式。另外，ActivityManager.RunningServiceInfo的clientPackage = android，表示键盘已绑定到系统。

可以将上述信息组合起来，以严格的方式确定软键盘是否可见。

如您所知，只有在可能发生键入事件时，才会显示android软件键盘。换句话说，只有在聚焦EditText时，键盘才可见。这意味着您可以使用OnFocusChangeListener来获取键盘可见与否的天气。

//Declare this Globally

public boolean isKeyBoardVisible = false;

//In OnCreate *[For Activity]*, OnCreateView *[For Fragment]*

text_send.setOnFocusChangeListener(new View.OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if(hasFocus)
            isKeyBoardVisible = true;
        else
            isKeyBoardVisible = false;
    }
});

现在您可以使用isKeyBoardVisible在类中的任何位置变量，以获取键盘为“打开”还是“不打开”的天气信息。对我来说效果很好。

注意：使用InputMethodManager以编程方式打开键盘时，此过程不起作用，因为它不会调用OnFocusChangeListener。

我将答案转换为Kotlin，希望这对Kotlin用户有所帮助。

private fun checkKeyboardVisibility() {
    var isKeyboardShowing = false

    binding.coordinator.viewTreeObserver.addOnGlobalLayoutListener {
        val r = Rect()
        binding.coordinator.getWindowVisibleDisplayFrame(r)
        val screenHeight = binding.coordinator.rootView.height

        // r.bottom is the position above soft keypad or device button.
        // if keypad is shown, the r.bottom is smaller than that before.
        val keypadHeight = screenHeight - r.bottom


        if (keypadHeight > screenHeight * 0.15) { // 0.15 ratio is perhaps enough to determine keypad height.
            // keyboard is opened
            if (!isKeyboardShowing) {
                isKeyboardShowing = true

            }
        } else {
            // keyboard is closed
            if (isKeyboardShowing) {
                isKeyboardShowing = false

            }
        }
    }
}

它与adjustNothing活动标志和生命周期事件一起使用。同样在Kotlin中：

/**
 * This class uses a PopupWindow to calculate the window height when the floating keyboard is opened and closed
 *
 * @param activity The parent activity
 *  The root activity that uses this KeyboardManager
 */
class KeyboardManager(private val activity: AppCompatActivity) : PopupWindow(activity), LifecycleObserver {

    private var observerList = mutableListOf<((keyboardTop: Int) -> Unit)>()

    /** The last value of keyboardTop */
    private var keyboardTop: Int = 0

    /** The view that is used to calculate the keyboard top  */
    private val popupView: View?

    /** The parent view  */
    private var parentView: View

    var isKeyboardShown = false
        private set

    /**
     * Create transparent view which will be stretched over to the full screen
     */
    private fun createFullScreenView(): View {
        val view = LinearLayout(activity)
        view.layoutParams = LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                ViewGroup.LayoutParams.MATCH_PARENT)
        view.background = ColorDrawable(Color.TRANSPARENT)
        return view
    }

    init {
        this.popupView = createFullScreenView()
        contentView = popupView

        softInputMode = LayoutParams.SOFT_INPUT_ADJUST_RESIZE or LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE
        inputMethodMode = INPUT_METHOD_NEEDED

        parentView = activity.findViewById(android.R.id.content)

        width = 0
        height = LayoutParams.MATCH_PARENT

        popupView.viewTreeObserver.addOnGlobalLayoutListener {
            val rect = Rect()
            popupView.getWindowVisibleDisplayFrame(rect)

            val keyboardTop = rect.bottom
            if (this.keyboardTop != keyboardTop) {

保持视图始终在键盘上方的有用方法

fun KeyboardManager.updateBottomMarginIfKeyboardShown(
        view: View,
        activity: AppCompatActivity,
        // marginBottom of view when keyboard is hide
        marginBottomHideKeyboard: Int,
        // marginBottom of view when keybouard is shown
        marginBottomShowKeyboard: Int
) {
    registerKeyboardTopObserver { bottomKeyboard ->
        val bottomView = ViewUtils.getFullViewBounds(view).bottom
        val maxHeight = ScreenUtils.getFullScreenSize(activity.windowManager).y
        // Check that view is within the window size
        if (bottomView < maxHeight) {
            if (bottomKeyboard < bottomView) {
                ViewUtils.updateMargin(view, bottomMargin = bottomView - bottomKeyboard +
                        view.marginBottom + marginBottomShowKeyboard)
            } else ViewUtils.updateMargin(view, bottomMargin = marginBottomHideKeyboard)
        }
    }
}

在哪里getFullViewBounds

fun getLocationOnScreen(view: View): Point {
    val location = IntArray(2)
    view.getLocationOnScreen(location)
    return Point(location[0], location[1])
}

fun getFullViewBounds(view: View): Rect {
     val location = getLocationOnScreen(view)
     return Rect(location.x, location.y, location.x + view.width,
            location.y + view.height)
 }

哪里getFullScreenSize

fun getFullScreenSize(wm: WindowManager? = null) =
            getScreenSize(wm) { getRealSize(it) }

private fun getScreenSize(wm: WindowManager? = null, block: Display.(Point) -> Unit): Point {
    val windowManager = wm ?: App.INSTANCE.getSystemService(Context.WINDOW_SERVICE)
            as WindowManager
    val point = Point()
    windowManager.defaultDisplay.block(point)
    return point
}

哪里updateMargin

fun updateMargin(
        view: View,
        leftMargin: Int? = null,
        topMargin: Int? = null,
        rightMargin: Int? = null,
        bottomMargin: Int? = null
) {
    val layoutParams = view.layoutParams as ViewGroup.MarginLayoutParams
    if (leftMargin != null) layoutParams.leftMargin = leftMargin
    if (topMargin != null) layoutParams.topMargin = topMargin
    if (rightMargin != null) layoutParams.rightMargin = rightMargin
    if (bottomMargin != null) layoutParams.bottomMargin = bottomMargin
    view.layoutParams = layoutParams
}

我这样做是这样的，但是只有当您的目标是关闭/打开键盘时，它才会重新显示。

关闭示例：（检查键盘是否已经关闭；如果没有关闭，则关闭）

imm.showSoftInput(etSearch, InputMethodManager.HIDE_IMPLICIT_ONLY, new ResultReceiver(null) {
                    @Override
                    protected void onReceiveResult(int resultCode, Bundle resultData) {
                        super.onReceiveResult(resultCode, resultData);
                        if (resultCode != InputMethodManager.RESULT_UNCHANGED_HIDDEN)
                            imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
                    }
                });

一个可能正在使用：

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    Log.d(
    getClass().getSimpleName(), 
    String.format("conf: %s", newConfig));

    if (newConfig.hardKeyboardHidden != hardKeyboardHidden) {
        onHardwareKeyboardChange(newConfig.hardKeyboardHidden);

        hardKeyboardHidden = newConfig.hardKeyboardHidden;
    }

    if (newConfig.keyboardHidden != keyboardHidden) {
        onKeyboardChange(newConfig.keyboardHidden);

        keyboardHidden = newConfig.hardKeyboardHidden;
    }

}

public static final int KEYBOARDHIDDEN_UNDEFINED = 0;
public static final int KEYBOARDHIDDEN_NO = 1;
public static final int KEYBOARDHIDDEN_YES = 2;
public static final int KEYBOARDHIDDEN_SOFT = 3;

//todo
private void onKeyboardChange(int keyboardHidden) {

}

//todo
private void onHardwareKeyboardChange(int hardKeyboardHidden) {

}

我写了样本。

该存储库可以帮助检测键盘状态，而无需假设“键盘应该超过屏幕的X部分”

如果您的应用程序支持AndroidR的api，则可以使用以下方法。

In kotlin :
    var imeInsets = view.rootWindowInsets.getInsets(Type.ime()) 
    if (imeInsets.isVisible) { 
        view.translationX = imeInsets.bottom 
    }

注意：这仅适用于AndroidR，低于android版本需要遵循其他一些答案，否则我会为此进行更新。
