处理来自Firebase Android的通知

我试图了解Firebase。我成功地收到了它的通知。但是，当我点击通知时，如何打开另一个活动

这是我的代码：

public class MyFirebaseMessagingService extends FirebaseMessagingService {

private static final String TAG = "MyFirebaseMsgService";

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    Log.d("msg", "onMessageReceived: " + remoteMessage.getData().get("message"));
    NotificationCompat.Builder builder = new  NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle("test")
            .setContentText(remoteMessage.getData().get("message"));
    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    manager.notify(0, builder.build());



}

这是关于通知的事，与firebase无关

您需要定义通知的操作

您需要定义通知的操作

您需要使用NotificationManager构建挂起的内容和通知

Intent intent = new Intent(this, MyActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.your_icon)
        .setContentTitle("Notification Title")
        .setContentText(messageBody)
        .setAutoCancel(true)
        .setContentIntent(pendingIntent);

NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());

正如托森所建议的，如果您正在从Firebase控制台发送推送通知，您需要将有效负载放入

键，您需要构建一个挂起的内容并使用NotificationManager进行通知

Intent intent = new Intent(this, MyActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.your_icon)
        .setContentTitle("Notification Title")
        .setContentText(messageBody)
        .setAutoCancel(true)
        .setContentIntent(pendingIntent);

NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());
