我通过BroadcastReceiver
拨打AlarmManager
并且它对我来说很好。
但是
这次我需要什么
I want to create multiple AlarmManager which call the same BroadcastReceiver Class.
这个过程的方法是什么?

您可以通过使用不同的请求代码为所使用的PendingIntent
设置闹钟来实现此目的。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。希望它有所帮助。
编辑:
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);
}
