}
@Override

如果我正确理解了您的问题，您希望键盘上的“完成”按钮执行一些操作。这应该可以解决问题：

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;
                }
});
