问题描述

我的应用程序目前正在接收文本，图像和Firebase控制台的推送通知。我也想将URL从我的Firebase控制台发送到应用用户。单击通知用户将被重定向到特定的URL，即www.facebook.com。如何在以下代码中执行此操作？
请看这张图片是我想要的

这是我在我的应用程序中实现的用于推送链接数据的代码 
 
 
  public class MyFirebaseMessagingService扩展了FirebaseMessagingService {
位图位图; 
 @Override 
 public void onMessageReceived（RemoteMessage remoteMessage）{
 String message = remoteMessage.getData（）。get（message）; 
 // imageUri将包含要显示的图像的URL，通知
 String imageUri = remoteMessage.getData（）。get（image）; 
 String link = remoteMessage.getData（）。get（link）; 
 
 //从接收到的URL获取位图图像
 bitmap = getBitmapfromUrl（imageUri）; 
 sendNotification（消息，位图，链接）; 
 
}

 *创建并显示包含收到的FCM消息的简单通知。

 private void sendNotification（String messageBody，Bitmap image，String link）{
 Intent intent = new Intent（this，MainActivity.class）; 
 intent.addFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP）; 
 intent.putExtra（LINK，link）; 
 PendingIntent pendingIntent = PendingIntent.getActivity（this，0 / * Request code * /，intent，
 PendingIntent.FLAG_ONE_SHOT）; 
 Uri defaultSoundUri = RingtoneManager.getDefaultUri（RingtoneManager.TYPE_NOTIFICATION）; 
 NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder（this）

 .setContentIntent（pendingIntent）; 
 NotificationManager notificationManager = 
（NotificationManager）getSystemService（Context.NOTIFICATION_SERVICE）; 
 
 notificationManager.notify（0 / *通知的ID * /，notificationBuilder.build（））; 
 
 public Bitmap getBitmapfromUrl（String imageUrl）{
 try {
 URL url = new URL（imageUrl）;

这是MainActivity打开链接在我的WebView或其他浏览器depand您的要求通过意图。
  if（getIntent（）。getExtras（）！= null ）{
 if（getIntent（）。getStringExtra（LINK）！= null）{
 Intent i = new Intent（this，WebViewActivity.class）; 
 i.putExtra（link，getIntent（）。getStringExtra（LINK））; 
 MainActivity.this.startActivity（i）; 
 finish（）; 
}} 
  
现在在WebViewActivity中获取链接并在WebView中加载url 
  WebView webView =（WebView）findViewById（R.id.webView）; 
 Intent i = getIntent（）; 
 String url = i.getStringExtra（link）; 
 webView.loadUrl（url）; 
  
 
My application is currently receiving Text , Image and both as a push notification from Firebase console. I want to send URL too as a notification from my Firebase console to the app user.On clicking the notification user shall be redirected to the specific url i.e. www.facebook.com .How can i do this in following code?
Kindly see the image thats what i want



Image From firebase notification console

            return null;

        }
    }
}



 解决方案 
This is the code that i have implemented in my app for pushing link with data
public class MyFirebaseMessagingService extends FirebaseMessagingService {
Bitmap bitmap;
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    String message = remoteMessage.getData().get("message");
    //imageUri will contain URL of the image to be displayed with Notification
    String imageUri = remoteMessage.getData().get("image");
    String link=remoteMessage.getData().get("link");

    //To get a Bitmap image from the URL received
    bitmap = getBitmapfromUrl(imageUri);
    sendNotification(message, bitmap,link);

}


/**
 * Create and show a simple notification containing the received FCM message.
 */

private void sendNotification(String messageBody, Bitmap image, String link) {
    Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("LINK",link);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setLargeIcon(image)/*Notification icon image*/
            .setSmallIcon(R.drawable.icon)
            .setContentTitle(messageBody)
            .setStyle(new NotificationCompat.BigPictureStyle()
                    .bigPicture(image))/*Notification with Image*/
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);
    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
public Bitmap getBitmapfromUrl(String imageUrl) {
    try {
        URL url = new URL(imageUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap bitmap = BitmapFactory.decodeStream(input);
        return bitmap;

    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        return null;

    }
}}

And this is MainActivity to open link in my WebView or other browser depand on your requirement through intents.
if (getIntent().getExtras() != null) {
        if (getIntent().getStringExtra("LINK")!=null) {
            Intent i=new Intent(this,WebViewActivity.class);
            i.putExtra("link",getIntent().getStringExtra("LINK"));
            MainActivity.this.startActivity(i);
            finish();
        }}

Now in WebViewActivity get link and load url in WebView
    WebView webView = (WebView) findViewById(R.id.webView);
    Intent i = getIntent();
    String url = i.getStringExtra("link");
    webView.loadUrl(url);
