我想用通知消息创建广播 AlarmManager(重复).我从 Pickers 传递我的日历对象.如果我不重新启动我的设备，它会正常工作.但是，当我重新启动设备时，如您所知，我的日历对象将为空.重新启动后如何管理重复的闹钟以及如何保留我的日历计划?谢谢你的想法.

i want to create broadcast AlarmManager(repeating) with Notification message.i pass my calender object from Pickers. If i don't reboot my device it works normally. However, when i reboot my device,as you know my calander object will be null. How can i manage my repeating alarm after rebooting and how can i hold my Calendar schedules? Thanks for your ideas.

public class MyReceiver extends BroadcastReceiver { private static final int PERIOD = 10000; final public static String ALARM_ID = "AlarmId"; final public static String NOTIFICATION_ID = "NotificationId"; @Override public void onReceive(Context ctxt, Intent i) { } static 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); }

推荐答案

您需要使用 BroadcastReceiver 并将其设置为响应 BOOT_COMPLETED 消息.例如

You need to use a BroadcastReceiver and set it to respond to BOOT_COMPLETED messages. For example

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>

处理代码中的消息

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闹钟时间表.

This will reset your alarm schedule on boot.
