你需要註冊一個BroadcastReceiver爲Intent.ACTION_SCREEN_OFF

因此，創建廣播接收器

這是你處理screen_off意圖。

private BroadcastReceiver receiver = new BroadcastReceiver() { 
public void onReceive(final Context context, final Intent intent) { 

    /* 
    * dispatch screen_off 
     * to handler method 
    */ 

    String iAction = intent.getAction(); 

    if (iAction.equals(Intent.ACTION_SCREEN_OFF)) 
    handleScreenAction(iAction); 

} 

}; 

現在過濾器註冊接收器。

static void registerReciever() { 
    IntentFilter myFilter = new IntentFilter(); 
    // Catch screen off event 
    myFilter.addAction(Intent.ACTION_SCREEN_OFF); 
    registerReceiver(receiver, myFilter); 
}
