推荐答案

当然可以，用Viewtree观测和全球布局监听器的帮助下，只要尝试以下提到的步骤

Yes you can, with the help of Viewtree Observer and global layout listener, just try below mentioned steps

1. 让您的布局的根视图


2. 获得Viewtree观察员此根，而在此之上添加一个全球布局的倾听者。

现在只要显示软键盘Android将重新大小的屏幕，您将收到你的听众来电。这就是它只有你现在需要做的事情就是计算高度，你的根视图有重新大小和原始大小后的差异。如果不同的是更多的则150认为这是一个键盘已经被夸大了。

now whenever soft keyboard is displayed android will re-size your screen and you will receive call on your listener. That's it only thing you now need to do is calculate difference between height which your root view has after re-size and original size. If difference is more then 150 consider this as a keyboard has been inflated.

下面是一个示例code

Below is a sample code

root.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener(){
     public void onGlobalLayout(){
           int heightDiff = root.getRootView().getHeight()- root.getHeight();
           // IF height diff is more then 150, consider keyboard as visible.  
        }
  });
