这应该工作，如果你需要检查键盘状态:

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);
}

UiUtils的地方。KEYBOARD_VISIBLE_THRESHOLD_DP = 100, dip()是一个anko函数，转换dpToPx:

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

现在终于可以直接从基于Kotlin的Android R开始了。

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

我是这样做的，但只有当你的目标是关闭/打开键盘时，它才有意义。

关闭示例:(检查键盘是否已经关闭，如果没有关闭)

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);
                    }
                });

试试这个，对我很有效

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    if (imm.isActive())
        //Keyboard is active

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");
    }

可以使用showSoftInput()和hideSoftInput()的回调结果来检查键盘的状态。完整的细节和示例代码在
