在Android的唤醒/休眠活动启动 [英] Start Activity on wake up/sleep in Android

问题描述

我想让它启动时，Android设备被唤醒计数，当Android设备被设置为休眠停止一个定时器。我什么也没找到，一个活动可能如何被触发
通过唤醒/休眠。

我希望你能帮助我与我的问题。

解决方案

我用一个BroadcastReceiver像timonvlad说，但ACTION_SCREEN_ON和ACTION_SCREEN_OFF不能用XM​​L被称为

所以我创建了一个服务。该服务在XML中进行注册，然后我用这个code

  OnOffReceiver延伸服务{public类@覆盖
公众的IBinder onBind（意向为arg0）{
    // TODO自动生成方法存根
    返回null;
}@覆盖
公众诠释onStartCommand（意向意图，诠释标志诠释startId）{
    registerReceiver（新广播接收器（）{        公共无效的onReceive（上下文的背景下，意图意图）{
                        //这发生在屏幕关闭
          }
        }，新的IntentFilter（Intent.ACTION_SCREEN_OFF））;
    registerReceiver（新广播接收器（）{          公共无效的onReceive（上下文的背景下，意图意图）{
                          //出现这种情况，当屏幕开启和屏幕锁停用
          }
        }，新的IntentFilter（Intent.ACTION_USER_ preSENT））;    返回START_STICKY;
}@覆盖
公共无效的onDestroy（）{
    super.onDestroy（）;
}
}
 

I want to make an timer which starts counting when the Android device is woken up and stops when the Android device is set to sleep. I found nothing, how a activity could be triggered by wake up/sleep.

I hope you can help me with my problem

解决方案

I used a BroadcastReceiver like timonvlad said but ACTION_SCREEN_ON and ACTION_SCREEN_OFF could not be called by XML so I created an service. The service has to be registered in the XML then I used this code

public class OnOffReceiver extends Service {

@Override
public IBinder onBind(Intent arg0) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    registerReceiver(new BroadcastReceiver() {

        public void onReceive(Context context, Intent intent) {
                        //This happens when the screen is switched off
          }
        }, new IntentFilter(Intent.ACTION_SCREEN_OFF));


    registerReceiver(new BroadcastReceiver() {

          public void onReceive(Context context, Intent intent) {
                          //This happens when the screen is turned on and screen lock deactivated
          }
        }, new IntentFilter(Intent.ACTION_USER_PRESENT));

    return START_STICKY;
}

@Override
public void onDestroy() {
    super.onDestroy();
}
}
