java - 创建具有不同 Intent 的多个通知

Question

我将尝试每次使用不同的参数创建多个本地通知，这是我创建通知的代码:

 public void setNotficition(int Time,String ProdName,String ProdDesc,String ProdID){
    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

    Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
    notificationIntent.addCategory("android.intent.category.DEFAULT");
    notificationIntent.putExtra("ProdName",ProdName);
    notificationIntent.putExtra("ProdDesc",ProdDesc);
    notificationIntent.putExtra("ProdID",ProdID);

    PendingIntent broadcast = PendingIntent.getBroadcast(this, 100, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Calendar cal = Calendar.getInstance();
    cal.add(Calendar.SECOND, Time);
    alarmManager.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),broadcast);
}

这是我的 BroadcastReceiver 代码:

    @Override
public void onReceive(Context context, Intent intent) {
    String ProdName= intent.getStringExtra("ProdName");
    String ProdDesc= intent.getStringExtra("ProdDesc");
    String ProdID= intent.getStringExtra("ProdID");

    int ID = Integer.parseInt(ProdID);
    Intent notificationIntent = new Intent(context, NotificationActivity.class);

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
    stackBuilder.addParentStack(NotificationActivity.class);
    stackBuilder.addNextIntent(notificationIntent);

    PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(context);

        Notification notification = builder.setContentTitle(ProdName)
                .setContentText(ProdDesc)
                .setTicker("New Message Alert!")
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentIntent(pendingIntent).build();
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify((int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE), notification);
}

每次接听最后一个电话

通知id在您的应用程序中应该是唯一的。

If a notification with the same id has already been posted by your application and has not yet been canceled, it will be replaced by the updated information.

NotificationManager notiManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);    
notiManager.notify(UNIQUE_ID, notification);

如果您使用PendingIntent.getBroadcast()方法，请为不同的通知使用不同的requestCode:

Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
notificationIntent.addCategory("android.intent.category.DEFAULT");
notificationIntent.putExtra("ProdName",ProdName);
notificationIntent.putExtra("ProdDesc",ProdDesc);
notificationIntent.putExtra("ProdID",ProdID);

PendingIntent broadcast = PendingIntent.getBroadcast(this, REQUEST_CODE, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

希望这会有所帮助!
