private fun isKeyboardVisible(rootView: View) =
    ViewCompat.getRootWindowInsets(rootView)!!.isVisible(WindowInsetsCompat.Type.ime())

我用这个作为基础:https://rogerkeays.com/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;

}

然后你可以用它来测试所有可能打开软键盘的字段(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);

当然不是一个理想的解决方案，但它可以完成工作。

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已经回复。但是，您可以通过检查#onMeasure中窗口大小是否改变来间接检测它。参见如何检查软件键盘的可见性在Android?。

private fun isKeyboardVisible(rootView: View) =
    ViewCompat.getRootWindowInsets(rootView)!!.isVisible(WindowInsetsCompat.Type.ime())

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。

试试这段代码，它真的工作，如果keyboardshow是显示的，那么这个函数返回真值....

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;
}
