嗨朋友我需要每天早上6点开始服务，并且需要每天早上8点停止服务，请任何人帮助我如何实现这一目标..

Answer 1

是的，您可以在AlarmManager

的帮助下完成此操作

public class AlarmReceiver extends BroadcastReceiver
{


@Override
public void onReceive(Context context, Intent intent)
{

    Toast.makeText(context, "Alarm Receiver", Toast.LENGTH_LONG).show();


}



public void setAlarm(Context context, Calendar cal1,String name)
{

    AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(context, AlarmReceiver.class);
     intent.putExtra("name", name);

    PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);

    final Calendar c = Calendar.getInstance();

    long interval = cal1.getTimeInMillis() - c.getTimeInMillis();
    Toast.makeText(context, "Interval=" + interval, Toast.LENGTH_LONG).show();

    Log.d("debug", "" + interval);
    Log.d("debug", "Current miliseconds =" + c.getTimeInMillis());

    am.set(AlarmManager.RTC, cal1.getTimeInMillis(), pi);

}

public void CancelAlarm(Context context)
{
    Intent intent = new Intent(context, AlarmReceiver.class);
    PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0);
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    alarmManager.cancel(sender);
}   
}

这是班级

您可以使用此类直接设置闹钟（不要忘记在AndroidManifest.xml中包含接收器）

希望这会对你有所帮助

创建 BroadcastReceiver

public class MyReceiver extends BroadcastReceiver {

  public void onReceive(Context context, Intent intent) {
            final String action = intent.getAction();

            if (action.equals(Intent.ACTION_TIME_CHANGED) ||
                action.equals(Intent.ACTION_TIMEZONE_CHANGED))
            {
                // get the current time here and start/stop your sevice depend on the time
            }
        }
}
