如果我正确理解你的问题，你需要键盘上的完成按钮来执行一些操作。这应该是诀窍：

url.setOnEditorActionListener(new EditText.OnEditorActionListener() { 
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { 
     if ((event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) || (actionId == EditorInfo.IME_ACTION_DONE)) { 
       // Your action goes here... 
     } 
    return false; 
       } 
});
