问题描述
您需要使用BroadcastReceiver并将其设置为响应BOOT_COMPLETED消息。例如
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。
解决方法
我想创建带有通知消息的广播AlarmManager（重复）。我从Pickers中传递日历对象。如果我不重启设备，它将正常工作。但是，当我重新启动设备时，您知道我的calander对象将为null。重新启动后如何管理重复警报以及如何保留日历时间表？感谢您的想法。
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,i,PendingIntent.FLAG_UPDATE_CURRENT);
alarManager.setRepeating(AlarmManager.RTC,c.getTimeInMillis(),PERIOD,pi);
}
