Question

I am using JSON to retrieve user data and I am also getting the image URL but how can I show the image instead of the URL? Currently it only shows the URL from the image.

Here is the code:

StringBuilder tweetResultBuilder = new StringBuilder();
            try {
                //get JSONObject from result
                JSONObject resultObject = new JSONObject(result);
                //get JSONArray contained within the JSONObject retrieved - "results"
                JSONArray tweetArray = resultObject.getJSONArray("results");
                //loop through each item in the tweet array
                for (int t=0; t<tweetArray.length(); t++) {
                    //each item is a JSONObject
                    JSONObject tweetObject = tweetArray.getJSONObject(t);
                //get the username and text content for each tweet
                tweetResultBuilder.append(tweetObject.getString("from_user")+": ");

           tweetResultBuilder.append(tweetObject.get("profile_image_url")+"\n");

                tweetResultBuilder.append(tweetObject.get("text")+"\n\n");
            }
        }

You should download and cashe you image first.
Please read this article Displaying Bitmaps Efficiently, and check Sample application

The shorter way to display image from url:

new DownloadImageTask((ImageView) findViewById(R.id.imageView1))
                .execute("http://java.sogeti.nl/JavaBlog/wp-content/uploads/2009/04/android_icon_256.png");




private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
    ImageView bmImage;

    public DownloadImageTask(ImageView bmImage) {
        this.bmImage = bmImage;
    }

    protected Bitmap doInBackground(String... urls) {
        String urldisplay = urls[0];
        Bitmap mIcon11 = null;
        try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);
        } catch (Exception e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return mIcon11;
    }

    protected void onPostExecute(Bitmap result) {
        bmImage.setImageBitmap(result);
    }
}
