android - 想要使用 Activity android 运行和停止服务

Question

我想知道我是否可以这样做，我想实现一个服务，该服务将在 Activity 启动时调用并且应该定期运行，当我通过关闭或按下来停止 Activity 时服务应该停止并警报管理器在 Activity 重新启动之前不应调用服务。还有一件事我想发送一些关于哪些服务可以运行并将结果返回给 Activity 的数据。目前我正在这样做.....

class MyService extends Service{

}

class MyScheduler extends BroadCastReceiver{

//Here alarm manager and pending intent is initialized to repeat after regular intervals.

}

class MyActivity extends Activity{

 onCreate(){

    //here i am binding the service

 }

}

MyBrodcastReceiver 添加到 list 中

请帮助并建议如何去做？

Answer 1

开始:

this.startService(new Intent(this, MyService.class));

停止:

this.stopService(new Intent(this, MyService.class));

为了让间隔创建一个定期调用 BrodcastReceiver 的服务，如下例所示:

在您的服务中:

// An alarm for rising in special times to fire the pendingIntentPositioning
private AlarmManager alarmManagerPositioning;
// A PendingIntent for calling a receiver in special times
public PendingIntent pendingIntentPositioning;

@Override
        public void onCreate() {
            super.onCreate();

            alarmManagerPositioning = (AlarmManager) getSystemService
                    (Context.ALARM_SERVICE);

            Intent intentToFire = new Intent(
                    ReceiverPositioningAlarm.ACTION_REFRESH_SCHEDULE_ALARM);

            pendingIntentPositioning = PendingIntent.getBroadcast(
                    this, 0, intentToFire, 0);



        };


@Override
    public void onStart(Intent intent, int startId) {

            long interval = 10 * 60 * 1000;
            int alarmType = AlarmManager.ELAPSED_REALTIME_WAKEUP;
            long timetoRefresh = SystemClock.elapsedRealtime();
            alarmManagerPositioning.setRepeating(alarmType,
                    timetoRefresh, interval, pendingIntentPositioning);

    }
