在android中侦听键盘显示或隐藏事件

我试图监听键盘显示或隐藏时发生的事件。这在Android中可能吗？当我开始我的活动时，我不想弄清楚键盘是显示还是隐藏，我想听听事件

请尝试以下代码：-

// from the link above
@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);


    // Checks whether a hardware keyboard is available
    if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
        Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
    } else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
        Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
    }
}

对于以下代码，您必须扩展LinearLayout

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    final int proposedheight = MeasureSpec.getSize(heightMeasureSpec);
    final int actualHeight = getHeight();

    if (actualHeight > proposedheight){
        // Keyboard is shown
    } else {
        // Keyboard is hidden
    }

    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

第一种仅适用于硬键盘。第二个是不可能做到的，我怎样才能覆盖onMeasure（int，int）？@alexandernajafi首先很抱歉，现在有几种方法可以检测键盘，所以请使用上述方法或查看链接。

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    final int proposedheight = MeasureSpec.getSize(heightMeasureSpec);
    final int actualHeight = getHeight();

    if (actualHeight > proposedheight){
        // Keyboard is shown
    } else {
        // Keyboard is hidden
    }

    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
