重新启动后重复警报管理器

您需要使用

BroadcastReceiver

BOOT_COMPLETED

在清单中注册您的

BroadcastReceiver

<receiver android:name=".MyBootReceiver">    <intent-filter>        <action android:name="android.intent.action.BOOT_COMPLETED" />    </intent-filter></receiver>

在代码中处理消息

MyBootReceiver.java

public class MyBootReceiver extends BroadcastReceiver {    private static final String TAG = "MyBootReceiver";    public void onReceive(Context context, Intent intent) {        Log.d(TAG, "onReceive");        Calendar cal = this.getMyCalendar();        this.scheduleAlarms(context, cal);    }    private Calendar getMyCalendar() {        // get your calendar object    }    private void scheduleAlarms(Context ctxt, Calendar c) {        AlarmManager alarManager = (AlarmManager) ctxt.getSystemService(Context.ALARM_SERVICE);        //notification servise          Intent i = new Intent(ctxt, ScheduledService.class);        i.putExtra(ALARM_ID, 1);        i.putExtra(NOTIFICATION_ID, 1);        PendingIntent pi = PendingIntent.getService(ctxt, 0, i, PendingIntent.FLAG_UPDATE_CURRENT);        alarManager.setRepeating(AlarmManager.RTC,c.getTimeInMillis(),PERIOD, pi);    }}

这将在启动时重置您的警报计划。
