創建一個每次運行的應用程序我打開屏幕

Question

我正在使用android studio，我想知道是否有辦法讓每次打開屏幕時都運行一個應用程序（例如屏幕鎖定）。我知道這已經被問過，但我不明白的地方把代碼這個.. 請幫助

Answer 1

<!-- SCREEN_ON BroadCast intent-filter --> 
 
< receiver android: name = ".broadcast.LockScreenReceiver" > 
 
    < intent - filter > 
 
    < action android: name = "android.intent.action.SCREEN_ON"/> 
 
    < action android: name = "android.intent.action.SCREEN_OFF"/> 
 
    < action android: name = "android.intent.action.USER_PRESENT"/> 
 
    < /intent-filter> 
 
</receiver > 
 

 

 
    //receive broadcast and do something 
 
    public void onReceive(Context context, Intent intent) { 
 
    if (Intent.ACTION_USER_PRESENT.equals(intent.getAction())) { 
 
     Log.e("scrennOn", "I'm comming!"); 
 
    } 
 
    }
