Question

我使用闹钟管理器使用按钮点击启动服务。它也在工作。我这样做了：

    Intent scheduleSMS = new Intent(SMSProjectDatabase.this,SendSMS.class);
    PendingIntent pendingIntent = PendingIntent.getService(SMSProjectDatabase.this,0, scheduleSMS,0);
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

    Calendar calendar = Calendar.getInstance();

    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.add(Calendar.SECOND,(int)GeneralUtil.calculateTimeDifference(getApplicationContext()));
    Log.i("SMS is scheduled after ",""+GeneralUtil.calculateTimeDifference(getApplicationContext()));

    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

此处SendSMS是一项由警报管理器启动的服务。但这不是我想在我的代码中启动服务的方式。我想使用Alarmmanager触发Broadcastreceiver的广播。然后Broadcastreceiver为我启动服务。

我的BroadCast接收器

公共类MyReceiver扩展了BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    //here i want to start the service through the alarm manager

}

}

但我不知道我该怎么做。请为我解决这个问题提供合适的解决方案。

Answer 1

您可以使用registerReceiver（）函数。但是你希望警报管理器触发广播。广播接收器用于在向应用程序广播某些内容时接收广播。

Answer 2

您只需在Service

内使用AlarmManager将您的内容用于调用onReceive()即可

@Override
public void onReceive(Context arg0, Intent arg1) {
  // To get AlarmManager instance working you can use Context arg0
  AlarmManager alarmManager = (AlarmManager) 
                                           arg0.getSystemService(ALARM_SERVICE); 
  // put your stuff to start Service using AlarmManager
}

通过广播接收器自动启动服务
