如果你的应用程序支持AndroidR的api，那么你可以使用下面的方法。

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

注意:这只适用于AndroidR和以下的android版本需要遵循一些其他的答案，否则我会更新它。

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);
    }
});

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

@iWantScala的回答很棒，但不适合我 rootView.getRootView().getHeight()总是有相同的值

一种方法是定义两个变量

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

添加全局监听器

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
}

工作正常

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");
    }

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) {

}
