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。

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

谢谢大家的回答，我是根据自己的情况想出来的

/**
 * Add global layout listener to observe system keyboard visibility
 */
private void initObserverForSystemKeyboardVisibility() {
    getRootView().getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            //Add your own code here
            Log.d("TEST_CODE", "isSystemKeyboardVisible:" + isSystemKeyboardVisible())
        }
    });
}


/**
 * Check system keyboard visibility
 * @return true if visible
 */
public boolean isSystemKeyboardVisible() {
    try {
        final InputMethodManager manager = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        final Method windowHeightMethod = InputMethodManager.class.getMethod("getInputMethodWindowVisibleHeight");
        final int height = (int) windowHeightMethod.invoke(manager);
        return height > 0;
    } catch (Exception e) {
        return false;
    }
}

我写了样本。

这个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”。

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");
    }

对于我所需要的需求来说，这要简单得多。希望这能有所帮助:

关于MainActivity:

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的默认基元布尔值将初始化为false。

然后检查如下值，并执行相应的操作:

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