当我设置 AlarmManager 时立即触发警报我在下面的代码中做错了什么

Question

Alaram 经理 Class

我使用 alaramManager.setRepeating 每次间隔一段时间后重复一次

public class AlarmService {

Long time;
AlarmManager alarmManager;
PendingIntent pendingIntent;
Context context;

public AlarmService(Context context){
    this.context = context;
}

public AlarmService(Context context, Long time) {
    this.time = time * 60000;
    Log.e("time",this.time+" AlaramService");
    this.context = context;
}

public void setAlarm() {
    alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    Intent i = new Intent(context, ReminderBroadcastReceiver.class);
    pendingIntent = PendingIntent.getBroadcast(context, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
    alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis(), time, pendingIntent);

    Log.e("time",time+" setAlarm");

}

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

}

将 AlarmManager 设置为在特定时间后调用

Long time = Long.valueOf(settingsData.getInterval().split(" ")[0]);
                AlarmService alarmService = new AlarmService(Setting.this,time);
                alarmService.cancelAlarm();
                alarmService.setAlarm();

用于通知的 ReminderBroadcastService

public class ReminderBroadcastReceiver extends BroadcastReceiver {


@Override
public void onReceive(final Context context, Intent intent) {
    Toast.makeText(context, "Received", Toast.LENGTH_SHORT).show();

    NotificationService notificationService = new NotificationService(context);
    notificationService.callNotification();
}

Answer 1

您正在通过 System.currentTimeMillis()

alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis(), time, pendingIntent);

用于设置闹钟功能的闹钟时间。这就是它立即触发的原因。传递未来的时间而不是像现在一样设置第二天的闹钟

alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis()+86400000L, time, pendingIntent);
