推荐答案

要做些什么，当用户presses您使用下面的空格键 -

To do something when the user presses the space key you use the following -

if((event.getAction()==KeyEvent.ACTION_DOWN)&&(key == KeyEvent.KEYCODE_SPACE)){
//put your code for whatever you what to do when the user presses space here
   }
}

如果您有多个edittexts，在上述code将

If you have multiple edittexts, in the above code put

if (edittext.hasFocus()){
    //do something for particular edit text
}

我想我知道为什么你的EditText不工作。当EditText上聚焦（选择），按键点击次数绕过你的活动，并去直奔的EditText。为了解决这个问题，你需要移动 onKeyListener 到 onKeyListener 为您的EditText。

I think I know why your edittext is not working. When the edittext is focused(selected), the key clicks are bypassing your activity and go in straight to the edittext. To solve this you need to move the onKeyListener into an onKeyListener for your edittext.

试试下面的code，而不是

Try the below code instead

edittext.setOnKeyListener(new OnKeyListener() {           
        @Override
        public boolean onKey(View v, int key, KeyEvent event) {
            if (event.getAction()==KeyEvent.ACTION_DOWN && key == KeyEvent.KEYCODE_ENTER) {
                //operation that you want on key press
                return true;
            }
            return false;
        }
    });
