Question

任何人都可以告诉我如何在Android应用程序中创建一个从当前时间开始的警报，它会在特定时间内每10分钟重复一次？

例如，根据不同情况，警报应重复的时间是2小时，另一种情况可能只是1:30小时，依此类推。

有没有办法做到这一点？

实际上我使用了从网上拿来的代码，如下所示：

public class MyAlarmService扩展Service {

@Override
    public void onCreate() {

        // TODO Auto-generated method stub

    }

    @Override
    public IBinder onBind(Intent intent) {

        // TODO Auto-generated method stub

        Toast.makeText(this, "MyAlarmService.onBind()", Toast.LENGTH_LONG)
                .show();

        return null;

    }

    @Override
    public void onDestroy() {

        // TODO Auto-generated method stub

        super.onDestroy();

        Toast.makeText(this, "MyAlarmService.onDestroy()", Toast.LENGTH_LONG)
                .show();

    }

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

        // TODO Auto-generated method stub

        super.onStart(intent, startId);

        Toast.makeText(this, "...", Toast.LENGTH_LONG)
        .show();

    }

    @Override
    public boolean onUnbind(Intent intent) {

        // TODO Auto-generated method stub

        Toast.makeText(this, "MyAlarmService.onUnbind()", Toast.LENGTH_LONG)
                .show();

        return super.onUnbind(intent);

    }

}

您可以使用BroadcastReceiver和PendingIntent。首先声明一个BroadcastReceiver：

public class EventAlarmReceiver extends BroadcastReceiver {

private long alarmTime;

@Override
public void onReceive(Context context, Intent intent1) {

    //declare the new time for the alarm, you can use a time stamp, for example in the next hour
    alarmTime = Calendar.getInstance().getTimeInMillis()+(60*60000); 

            //set an intent to the Receiver
    Intent intent = new Intent(context, EventAlarmReceiver.class);

             //set an PendingIntent to the Intent
    PendingIntent pendingIntent = PendingIntent.getBroadcast(
                getApplicationContext(), 234324243, intent, 0);

            //add to the System Alarm Manager
    AlarmManager alarmManager = (AlarmManager) getSystemService(Activity.ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC, alarmTime, pendingIntent);
}

}

并在活动中启动闹钟：

Intent intent = new Intent(context, EventAlarmReceiver.class);

        PendingIntent pendingIntent = PendingIntent.getBroadcast(
                getApplicationContext(), 234324243, intent, 0);

        AlarmManager alarmManager = (AlarmManager)   getSystemService(Activity.ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC, time, pendingIntent);
