如果单击推送通知，则在 WebView 中加载特定 URL 页面

Question

我是 Android Studio 的新手，对此有疑问。

所以我有一个使用 Webview 的 android 应用程序。我还实现了 FCM 推送通知。 当我点击通知时，它直接打开主页。如果我想在点击通知时打开应用中的特定页面怎么办？

这里是主要活动

class MainActivity : Activity() {
    private val URL = "https://thelink.pl"
    lateinit var webView: WebView
    private var notificationId: Int = 0;

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        this.requestWindowFeature(Window.FEATURE_NO_TITLE)
        webView = createView()
        setContentView(webView)

        firebaseInstanceToken() //get token
        subscibeToTopics("androidUsers")
    }

这是我的 FCM 服务

 // [START receive_message]
    override fun onMessageReceived(remoteMessage: RemoteMessage) {
        //check if message contains a data payload
        remoteMessage
                .data.isNotEmpty().let {
            Log.d("isData", "Message data payload: " + remoteMessage.data)
                    theMessageBody = remoteMessage.data.get("body").toString()
                    theMessageTitle = remoteMessage.data.get("title").toString()
                    theMessageDetail_ = remoteMessage.data.get("messageDetail").toString()
                    sendNotification(theMessageBody, theMessageTitle, theMessageDetail_)
        }

        //check if the message contains a notification payload
        remoteMessage
                .notification?.let {
                    theMessageBody = it.body!!
                    theMessageTitle = it.title!!
                    sendNotification(theMessageBody, theMessageTitle, theMessageDetail_)
        }
    }

感谢任何帮助..谢谢

您是否通过 FCM 发送了特定页面？然后使用意图发送。

就我而言，

private void sendNotification(String messageBody) {
        Dlog.e("messageBody = " + messageBody);

        try {
            JSONObject jsonBody = new JSONObject(messageBody);

            int pushType = jsonBody.getJSONObject("data").getInt("pushType");
            String pushTitle = jsonBody.getString("title");
            String textBody = "";
            String contentText = "";
            PendingIntent pendingIntent = null;



                String push_title = jsonBody.getString("title");
                String boardContent = jsonBody.getJSONObject("data").getString("boardContent");
                String boardUrl = jsonBody.getJSONObject("data").getString("boardUrl");

                textBody = boardContent;
                contentText = boardContent;

                if (boardUrl.equals("")){
                    Intent intent = new Intent(this, SplashActivity.class);
                    pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
                }else {
                    Intent intent = new Intent(this, PushWebViewActivity.class);
                    intent.putExtra("push_title", push_title);
                    intent.putExtra("boardUrl", boardUrl);
                    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
                    pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
                }


            Bitmap icon2 = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);

            NotificationCompat.BigTextStyle bigText = new NotificationCompat.BigTextStyle();
            bigText.bigText(textBody);

            NotificationCompat.Builder notificationBuilder;
            NotificationManager notificationManager =
                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);


            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                NotificationChannel mChannel = new NotificationChannel("channel", "channel_nm", NotificationManager.IMPORTANCE_HIGH);
                mChannel.setVibrationPattern(new long[]{500, 500, 500, 500});
                mChannel.setLightColor(ContextCompat.getColor(getApplicationContext(), R.color.colorPrimary));
                AudioAttributes att = new AudioAttributes.Builder()
                        .setUsage(AudioAttributes.USAGE_NOTIFICATION)
                        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                        .build();
                mChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
                mChannel.enableVibration(true);
                mChannel.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION), att);
                notificationManager.createNotificationChannel(mChannel);
                notificationBuilder = new NotificationCompat.Builder(getApplicationContext(), mChannel.getId());
            } else {
                notificationBuilder = new NotificationCompat.Builder(getApplicationContext());
            }
            notificationBuilder
                    .setLargeIcon(icon2)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle(pushTitle)
                    .setContentText(contentText)
                    .setStyle(bigText)
                    .setLights(ContextCompat.getColor(getApplicationContext(), R.color.colorPrimary), 3000, 3000)
                    .setVibrate(new long[]{500, 500, 500, 500})
                    .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                    .setAutoCancel(true)
                    .setPriority(NotificationCompat.PRIORITY_MAX)
                    .setContentIntent(pendingIntent);


            int random_num = (int) ((new Date().getTime() / 1000L) % Integer.MAX_VALUE);
            notificationManager.notify(random_num, notificationBuilder.build());
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }

我从 FCM 获取 url 并发送到页面和 webView 加载 url
