EditText中onEditorAction监听事件执行两次

 1 public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {  
 2         //以下方法防止两次发送请求  
 3         if (actionId == EditorInfo.IME_ACTION_SEND ||  
 4                 (event != null && event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {  
 5             switch (event.getAction()) {  
 6                 case KeyEvent.ACTION_UP:  
 7                     //发送请求  
 8                     String keyWord = et_search.getText().toString().trim();  
 9                     if (null == keyWord)  
10                         keyWord = "";  
11                     dismisspopup();  
12                     LogUtils.d("向服务器发送搜索请求：" + keyWord);  
13                     //发起查询  
14                     searchByKeyWord(keyWord);  
15                     hideSoftInput();  
16                     return true;  
17                 default:  
18                     return true;  
19             }
