Question

我的应用正在执行人员活动识别，并通知用户他们是否不够活跃。我正在一个正在运行的前台服务中读取加速度计的数据。目前我正在尝试在用户休眠时启动和停止服务（例如，用户将睡眠时间间隔设置为晚上8点 - 早上8点），因此应该停止服务并在指定时间后重新开始服务。目前，以下代码不起作用，我不知道为什么。有什么建议吗？

注意：我知道，我将以某种方式使代码重用Calendar实例，这仅用于调试目的并使其首先运行。

Date startSleepingHours = mUser.getStartSleepingHours();
    Date stopSleepingHours = mUser.getStopSleepingHours();
    //Create alarm manager
    AlarmManager alarmMgr0 = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

    Calendar cur_cal = new GregorianCalendar();
    cur_cal.setTimeInMillis(System.currentTimeMillis());//set the current time and date for this calendar

    Calendar cal = new GregorianCalendar();
    cal.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR));
    cal.set(Calendar.HOUR_OF_DAY, startSleepingHours.getHours());
    cal.set(Calendar.MINUTE, startSleepingHours.getMinutes());
    cal.set(Calendar.SECOND, cur_cal.get(Calendar.SECOND));
    cal.set(Calendar.MILLISECOND, cur_cal.get(Calendar.MILLISECOND));
    cal.set(Calendar.DATE, cur_cal.get(Calendar.DATE));
    cal.set(Calendar.MONTH, cur_cal.get(Calendar.MONTH));

    Intent startServiceIntent = new Intent(ActiveMinutesActivity.this, IntentBroadcastedReceiver.class);
    Intent stopServiceIntent = new Intent(ActiveMinutesActivity.this, IntentBroadcastedReceiver.class);
    stopServiceIntent.putExtra("command", "STOP_SERVICE");

    PendingIntent stopServicePIntent = PendingIntent.getService(ActiveMinutesActivity.this, 0, stopServiceIntent, 0);

    PendingIntent startServicePIntent = PendingIntent.getService(ActiveMinutesActivity.this, 1, startServiceIntent, 0);

    AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 60 * 1000, stopServicePIntent);


    Calendar cal2 = new GregorianCalendar();
    cal2.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR));
    cal2.set(Calendar.HOUR_OF_DAY, stopSleepingHours.getHours());
    cal2.set(Calendar.MINUTE, stopSleepingHours.getMinutes());
    cal2.set(Calendar.SECOND, cur_cal.get(Calendar.SECOND));
    cal2.set(Calendar.MILLISECOND, cur_cal.get(Calendar.MILLISECOND));
    cal2.set(Calendar.DATE, cur_cal.get(Calendar.DATE));
    cal2.set(Calendar.MONTH, cur_cal.get(Calendar.MONTH));


    alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal2.getTimeInMillis(), 60 * 1000, startServicePIntent);

我的Receiver课程：

public class IntentBroadcastedReceiver extends BroadcastReceiver {
public IntentBroadcastedReceiver() {
}

@Override
public void onReceive(Context context, Intent intent) {
    if(intent.getExtras() != null){
        if(intent.getExtras().get("command").equals("STOP_SERVICE")){
            context.stopService(new Intent(context, ActiveMinutesService.class));
        }else {
            context.startService(new Intent(context, ActiveMinutesService.class));
        }
    }

}
}

您是否已将IntentBroadcastedReceiver定义为AndroidManifest.xml中的接收器？即：

<receiver android:name=".IntentBroadcastedReceiver "></receiver>

在特定时间安排服务的开始和停止
