Question

我的应用程序当前正在接收来自Firebase控制台的文本，图片和两者作为推送通知。我也希望将来自我的Firebase控制台的通知发送给应用用户。点击通知后，用户将被重定向到特定的网址，即www.facebook.com。如何在以下代码中执行此操作？ Kindly see the image thats what i want

        // here in onMessageReceived whether the app is in the foreground or background. Data messages are the type
        // traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app
        // is in the foreground. When the app is in the background an automatically generated notification is displayed.
        // When the user taps on the notification they are returned to the app. Messages containing both notification

这是我在我的应用中实现的用于推送数据链接的代码

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;

    }
}}

这是MainActivity在我的WebView或其他浏览器中打开链接，并通过意图打开你的需求。

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WebView中的链接和加载URL

    WebView webView = (WebView) findViewById(R.id.webView);
    Intent i = getIntent();
    String url = i.getStringExtra("link");
    webView.loadUrl(url);
