            Intent pushNotification = new Intent(Config.PUSH_NOTIFICATION);
            pushNotification.putExtra("message", message);
            LocalBroadcastManager.getInstance(this).sendBroadcast(pushNotification);

            Intent resultIntent = new Intent(getApplicationContext(), Notification_Page.class);
            startActivity(resultIntent);
        } else {
            Intent resultIntent = new Intent(getApplicationContext(), Notification_Page.class);
            startActivity(resultIntent);
        }
    }

推荐答案

您可以在通知中设置待处理的意图.因此，首先创建一个待处理的意图:

You can set a pending intent in to your notification. So first create a pending intent:

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, Destination.class), 0);

然后将其添加到您的 NotificationBuilder 中，您可以在其中定义通知的标题，描述等，并使用以下参数:

Then add to your NotificationBuilder, where you define the title, description, etc.. of the notification, the following parameter:

builder.setContentIntent(contentIntent)

更新:

您的代码中已经有您的 NotificationCompatBuilder .

You have your NotificationCompatBuilder already in your code.

替换此:

NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.app_logo_a)
                .setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getNotification().getBody());

与此:

PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, Destination.class), PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.app_logo_a)
                .setContentTitle(remoteMessage.getData().get("title"))
                .setContentText(remoteMessage.getNotification().getBody())
                .setContentIntent(contentIntent);
