我通过AlarmManager调用broadcastReceiver它对我来说很好.

但

这次我需要什么

我想创建多个AlarmManager,它调用相同的broadcastReceiver类.

这个过程的方法是什么？

解决方法:

您可以通过使用与所使用的PendingIntent不同的请求代码设置警报来实现.确保每个警报都有唯一的请求代码.然后用一个广播接收器接收它们.

要记住的另一件事是,如果设备重新启动,则待处理的意图不再存在.因此,您必须使用另一个接收器来确定设备是否重新启动.您必须保存唯一的请求代码,然后当设备重新启动时,您必须使用相同的请求代码恢复警报.希望能帮助到你.

广播接收器

package com.your.package;import androID.content.broadcastReceiver;import androID.content.Context;import androID.content.Intent;import androID.util.Log;public class AlarmReceiver extends broadcastReceiver {    @OverrIDe    public voID onReceive(Context context, Intent intent) {        String Noti_Title = intent.getExtras().getString("Title");        String Noti_message = intent.getExtras().getString("notes");        int Noti_code = intent.getExtras().getInt("code");        Log.d("AlarmRecIEver", Noti_Title + " " + Noti_message);        Intent myIntent = new Intent(context, NotificationService.class);        myIntent.putExtra("Title", Noti_Title);        myIntent.putExtra("notes", Noti_message);        myIntent.putExtra("code", Noti_code);        context.startService(myIntent);    }}

服务：

package com.your.package;import androID.app.Notification;import androID.app.notificationmanager;import androID.app.PendingIntent;import androID.app.Service;import androID.content.Intent;import androID.media.ringtone;import androID.media.ringtoneManager;import androID.net.Uri;import androID.os.IBinder;public class NotificationService extends Service {    private notificationmanager mManager;    @OverrIDe    public IBinder onBind(Intent arg0) {        // Todo auto-generated method stub        return null;    }    @OverrIDe    public voID onCreate() {        super.onCreate();    }    @SuppressWarnings({ "static-access", "deprecation" })    @OverrIDe    public voID onStart(Intent intent, int startID) {        super.onStart(intent, startID);        String Noti_Title = intent.getExtras().getString("Title");        String Noti_message = intent.getExtras().getString("notes");        int Noti_Code = intent.getExtras().getInt("code");        mManager = (notificationmanager) this.getApplicationContext().getSystemService(this.getApplicationContext().NOTIFICATION_SERVICE);        Intent intent1 = new Intent(this.getApplicationContext(), MainActivity.class);        Notification notification = new Notification(R.drawable.ic_launcher , Noti_Title , System.currentTimeMillis());        intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_top | Intent.FLAG_ACTIVITY_CLEAR_top);        PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this.getApplicationContext(), 0, intent1, PendingIntent.FLAG_UPDATE_CURRENT);        notification.flags |= Notification.FLAG_auto_CANCEL;        notification.setLatestEventInfo(this.getApplicationContext(),Noti_Title , Noti_message , pendingNotificationIntent);        notification.vibrate = new long[] { 100L, 100L, 200L, 500L };        mManager.notify(Noti_Code , notification);        try {            Uri notification_uri = ringtoneManager.getDefaultUri(ringtoneManager.TYPE_NOTIFICATION);            ringtone r = ringtoneManager.getringtone(getApplicationContext(), notification_uri);            r.play();        } catch (Exception e) {}    }    @OverrIDe    public voID onDestroy() {        // Todo auto-generated method stub        super.onDestroy();    }}

用法：

public voID SetAlarm(Calendar calendar, int reqCode) {        String datename = IDea.getText().toString();        String dateNote = note.getText().toString();        Log.d("SetAlarm Texts", "Date : " + datename + " Note: " + dateNote);        Intent myIntent = new Intent(mActivity, AlarmReceiver.class);        myIntent.putExtra("Title", "Her : " + datename);        myIntent.putExtra("notes", dateNote);        myIntent.putExtra("code", reqCode);        PendingIntent pendingIntent = PendingIntent.getbroadcast(mActivity,                reqCode, myIntent, 0);        AlarmManager alarmManager = (AlarmManager) mActivity                .getSystemService(Context.ALARM_SERVICE);        alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(),                pendingIntent);    }
