How to fetch multiple images from url using Drawable in android?

private Drawable LoadImageFromWebOperations(String url) {
        try {
            InputStream is = (InputStream) new URL(url).getContent();
            Drawable d = Drawable.createFromStream(is, "icon");
            return d;
        } catch (Exception e) {
            System.out.println("Exc=" + e);
            return null;
        }
    }

I'm using this function to return drawable image but I'm not getting how to bind list of images to gridview..

Please help me.

Try looking into this [Link](https://github.com/nostra13/Android-Universal-Image-Loader). It does a lot of work out of the box for you — Abhay Kumar, Dec 01 '12 at 07:15

Simply give url to "imgaeUrl" field

URL url = new URL(imageUrl);
HttpURLConnection connection  = (HttpURLConnection) url.openConnection();

InputStream is = connection.getInputStream();
Bitmap img = BitmapFactory.decodeStream(is);  

imageView.setImageBitmap(img );

and set imageview

for(int i=0; i hm = imageList.get(1); drawable.add(LoadImageFromWebOperations(hm.get(TAG_IMAGE))); Toast.makeText(getApplicationContext(), hm.get(TAG_IMAGE), Toast.LENGTH_LONG).show(); } – shivani patel Dec 01 '12 at 07:26
