android SEND鍵崩潰

Question

我需要檢查輸入鍵來啓動搜索例程。除一些鍵盤外的所有作品似乎都有一個SEND按鈕，而不是ENTER按鈕。當這個按下時代碼轉儲。下面有一個小樣本。有任何想法嗎？

tx1.setOnEditorActionListener (new OnEditorActionListener() { 
    @Override 
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) { 
     System.out.println("Key: " + event.getKeyCode()); //BLOWS UP HERE 
     if (event.getAction() == KeyEvent.ACTION_DOWN) { 
      if (event.getKeyCode() == KeyEvent.KEYCODE_ENTER) { 
       // ... 
      } 
     } 
    } 
}

我相信事件在這種情況下爲空。爲了檢測軟鍵盤上的發送動作，你的onEditorActionListener實際上應該這樣做。

onEditorAction(TextView v, int actionId, KeyEvent event){ 
    if(actionId == EditorInfo.IME_ACTION_SEND){ 
     send(); 
    } 
    return false;// so the softkeyboard will still close after pressing 'send' 
}
