在我的情况下，我只有一个编辑文本来管理我的布局，所以我想出了这个解决方案。 它工作得很好，基本上它是一个自定义的EditText，它监听焦点，并在焦点改变或按下后退/完成按钮时发送本地广播。 要工作，你需要在你的布局与android: focableintouchmode ="true"和android:focusableInTouchMode="true"，因为当你调用clearFocus()的焦点将被重新分配到第一个可聚焦的视图。 虚拟视图示例:

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

额外的信息

检测布局变化差异的解决方案效果不太好，因为它强烈依赖于屏幕密度，因为100px在某些设备上可能很大，而在其他设备上可能没有，你可能会得到误报。 另外，不同的厂商有不同的键盘。

这是如何在一个片段中使用软键盘状态监听器(适用于API 21及以上)

    private var currentWindowInsets: WindowInsetsCompat = WindowInsetsCompat.Builder().build()

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        setWindowInsetsAnimationCallback(requireView().rootView, object : Callback(DISPATCH_MODE_CONTINUE_ON_SUBTREE) {
            override fun onProgress(insets: WindowInsetsCompat, runningAnimations: MutableList<WindowInsetsAnimationCompat>): WindowInsetsCompat {
                currentWindowInsets = insets
                return insets
            }
    
            override fun onEnd(animation: WindowInsetsAnimationCompat) {
                super.onEnd(animation)
                val keyboardIsVisible = currentWindowInsets.isVisible(WindowInsetsCompat.Type.ime())
                if (keyboardIsVisible) { //do your stuff }
            }
        })
    }

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();
            }
        }
});

你可以参考这个答案- https://stackoverflow.com/a/24105062/3629912

每次都很管用。

adb shell dumpsys window InputMethod | grep "mHasSurface"

如果软件键盘可见，它将返回true。

A可能会使用:

@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) {

}

我创建了一个可以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，并按如下方式使用:

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