監聽不到android 的 Home 鍵

應用程式監聽不了android 機的HOME KEY事件。

 

 @Override public boolean onKeyDown(int keyCode, KeyEvent event) {  // TODO Auto-generated method stub  if(keyCode==3)//HOME鍵碼為3  {   HomeKeyNum+=1;   Log.i("gogler", "home key pressed time is: "+HomeKeyNum);  }  return super.onKeyDown(keyCode, event); }

 

 

實驗結果沒有預期日誌輸出，把鍵碼換成BACK鍵碼4則可以監聽到。

 

官方解釋：

Key code constant: Home key. This key is handled by the framework and is never delivered to applications.
