创建具有不同意图的多通知

Question

我每次都会尝试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);
}

每次接最后一个电话

Answer 1

您可以通过每次更改通知 ID 创建多个通知。

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

getBroadcast 调用的第二个参数是 "notification id"（即您的情况下的 100）。如果生成多个通知，只需使用不同的不同通知 ID。

希望对你有所帮助:-)

Answer 2

通知已创建并链接到一个 ID，此 ID 可用于修改或更新现有通知，无论您是要更改意图还是仅更改堆栈的行为。

Answer 3

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，请对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);

希望对您有所帮助！
