android - 当我点击在后台运行的通知时，它总是调用 MainActivity ，我如何调用我的 WebVIew

Question

当我点击在后台运行的通知时，它总是调用 MainActivity，当我在应用程序中单击时，我从 Firebase Cloud Messing 发送了 url，它可以打开我创建的 WebView，但如果我在关闭应用程序时单击它，它总是调用 MainActivity。没有任何错误，我认为它不会调用任何 if-clause 。请帮忙，对不起我的英语。

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    public MyFirebaseMessagingService() {
        super();
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);


        if (remoteMessage.getData().size() <= 0){

            String title = remoteMessage.getNotification().getTitle();
            String body = remoteMessage.getNotification().getBody();

            MessageHelper.displayMessage(getApplicationContext(), title, body);
        }

        if(remoteMessage.getData().size() > 0){

            String title = remoteMessage.getNotification().getTitle();
            String body = remoteMessage.getNotification().getBody();
            String url = remoteMessage.getData().get("url");

            MessageHelper.displayNotification(getApplicationContext(), title, body, url);
        }
    }

}

公共(public)类 MessageHelper {

public static void displayMessage(Context context, String title, String body){

    Intent intent = new Intent(context, NewsFragment.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

    PendingIntent pendingIntent = PendingIntent.getActivity(
            context,
            0,
            intent,
            PendingIntent.FLAG_UPDATE_CURRENT
    );

    NotificationCompat.Builder builder =
            new NotificationCompat.Builder(context, MainActivity.CHANNEL_ID)
                    .setSmallIcon(R.drawable.ic_notifications)
                    .setContentTitle(title)

您必须读取传入的 Intent OnCreate()

Intent read_int = getIntent();
Log.d("INTENT", read_int.toUri(0));

然后您可以分解传入的 Uri 请求:

String uri = read_int.getStringExtra("uri");   // your data sent over FCM

然后是条件，你想启动什么 Activity :

if(uri != null){
   Intent openWV = new Intent(CurrentActivity.this, MyWebViewActivity.class);
   openWV.putExtra("open_url", uri);   // optional parameters
   CurrentActivity.this.startActivity(openWV);
}
