How to get the url of image from a json file

Use Jsoup to solve this problem in easiest

http://www.jsoup.org/cookbook/introduction/parsing-a-document/

Use this code

   ArrayList<HashMap<String, String>> searchList = new ArrayList<HashMap<String, String>>();
  XMLParser parser = new XMLParser();
  String xml = parser.getXmlFromUrl(URL); // getting XML from URL
  Document doc = parser.getDomElement(xml); // getting DOM element
  NodeList nl = doc.getElementsByTagName(KEY_PRODUCT);
  for (int i = 0; i < nl.getLength(); i++) {
  Cursor cousor_image = null;
  HashMap<String, String> map = new HashMap<String, String>();
  Element e = (Element) nl.item(i);
      map.put(KEY_PRODUCT_ID, parser.getValue(e, KEY_PRODUCT_ID));
      searchList.add(map);
      Element elm = (Element) n3.item(0);

This is code define im XMLparser classes

    DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        xml = EntityUtils.toString(httpEntity);
        Log.i("XML Parser", "xml=" + xml);

Below code will help to collect the bitmap to image

   public void DisplayImage(String url, ImageView imageView) {
    imageViews.put(imageView, url);
    Bitmap bitmap = memoryCache.get(url);
    if (bitmap != null){
        imageView.setImageBitmap(bitmap);

    }

    else {
        queuePhoto(url, imageView);
        imageView.setImageResource(stub_id);
    }
}

And finally memorycache class

     import java.lang.ref.SoftReference;
     import java.util.Collections;
     import java.util.HashMap;
     import java.util.Map;
     import android.graphics.Bitmap;

     public class MemoryCache {
private Map<String, SoftReference<Bitmap>> cache = Collections
        .synchronizedMap(new HashMap<String, SoftReference<Bitmap>>());

public Bitmap get(String id) {
    if (!cache.containsKey(id))
        return null;
    SoftReference<Bitmap> ref = cache.get(id);
    return ref.get();
}

public void put(String id, Bitmap bitmap) {
    cache.put(id, new SoftReference<Bitmap>(bitmap));
}

public void clear() {
    cache.clear();
}

}
