應用程序監聽不了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志輸出，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.
