我必须显示demo link

中的图片

这是数据有效载荷数据

"image":"http:\/\/demo.ivdisplays.net\/broadcast\/school_admin\/notification

我必须在推送通知中的以下链接中显示图像，就像电子商务应用程序一样。

试试这个，会起作用

NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder nBuilder = new NotificationCompat.Builder(this);

Bitmap bitmap = getBitmapFromURL(url);

                            NotificationCompat.BigPictureStyle s = new NotificationCompat.BigPictureStyle().bigPicture(bitmap);
                            s.setSummaryText("Image");
                            nBuilder.setStyle(s);
                          nBuilder.setSmallIcon(R.mipmap.ic_launcher);

创建方法getBitmapFromURL

public Bitmap getBitmapFromURL(String strURL) {
    try {
        URL url = new URL(strURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

mNotificationManager.notify(0, nBuilder.build());

如何在android推送通知中显示链接中的图像？
