广播意图过滤器生成的 Android 推送通知将替换为旧通知

Question

当我放置消息时，我正在处理一个项目，然后我使用广播将其作为通知发送给另一个用户，但是当我再次发送新消息时，请替换为旧通知而不是创建新通知

以下是我用于生成通知的代码

NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
inboxStyle.addLine(message);
Notification notification;
notification = mBuilder.setSmallIcon(icon).setTicker(title).setWhen(0)
        .setAutoCancel(true)
        .setContentTitle(title)
        .setContentIntent(resultPendingIntent)
        .setSound(alarmSound)
        .setStyle(inboxStyle)
        .setColor(color)
        .setSmallIcon(setNotificationIcon(mBuilder))
        .setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
        .setContentText(message)
        .build();
NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(Config.NOTIFICATION_ID, notification);

广播代码

public class IncomingReceiver extends BroadcastReceiver {
    public static final String CUSTOM_INTENT = "jason.wei.custom.intent.action.TEST";
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(CUSTOM_INTENT)) {
            String message = intent.getStringExtra("message");
            String chat_id = intent.getStringExtra("chat_id");
            String username = intent.getStringExtra("username");
            String chatType = intent.getStringExtra("chatType");
            MyFirebaseMessagingService mMyFirebaseMessagingService = new MyFirebaseMessagingService();
            Log.e("CHATID BROADCADST",chat_id);
            Intent mIntent1;
            if(chatType.equalsIgnoreCase("group")){
                mIntent1=new Intent(context,ActivityChatMyGroup.class);
            }else {
                mIntent1=new Intent(context,ActivityChat.class);
            }
            Bundle mBundle=new Bundle();
            mBundle.putString("name",username);
            mIntent1.putExtras(mBundle);
            mMyFirebaseMessagingService.showChatNotificationMessage(context, chat_id, username, message, mIntent1);
        }
    }
}

>每次显示通知时，都应递增Config.NOTIFICATION_ID。如果两个通知具有相同的通知 ID，则将替换以前的通知。

维护一个变量(静态或基于首选项等(并在您的方法中递增它

//偏好

int notificationId = PreferenceManager.getDefaultSharedPreferences(context).getInt("Notification_ID", 0);
notificationId++;
PreferenceManager.getDefaultSharedPreferences (context).edit().putInt("Notification_ID", notificationId).apply();

然后使用此变量

notificationManager.notify(notificationId, notification);
