How to display image from Url in android?

Hello I have set properdata and my code is working but dont know what wrong images not display in gridview it only display black darkable images. Here is my code:

String response=sb.toString();
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        InputSource is1 = new InputSource();
        is1.setCharacterStream(new StringReader(response));
        Document doc = db.parse(is1);
        Element root = doc.getDocumentElement();

        NodeList nodes = root.getElementsByTagName("Photo");
        for (int i = 0; i < nodes.getLength(); i++) 
        {
            Element element = (Element) nodes.item(i);

            if(trmap.containsKey(strPhotoId))
            {

                trmap.clear();
            }
            if(trmapother.containsKey(strphotoidother))
            {
                trmapother.clear();
            }

            NodeList ProfilePhoto = element.getElementsByTagName("ProfilePhoto");
            Element line1 = (Element) ProfilePhoto.item(0);
            photoimg= getCharacterDataFromElement(line1);

            NodeList Count = element.getElementsByTagName("Count");
            Element line2 = (Element) Count.item(0);
            strCount= getCharacterDataFromElement(line2);

            for(int k=0; k<Integer.parseInt(strCount); k++)

Your code is so lengthy, I can't read all but, I can suggest you to try using this code just pass the URL and

    Drawable drawable_from_url(String url, String src_name) throws java.net.MalformedURLException, java.io.IOException      {         
return Drawable.createFromStream(((java.io.InputStream)new java.net.URL(url).awagetContent()), src_name);    
 } 

---

Just use the following method to draw image from url:

Drawable drawable_from_url(String url, String src_name) throws java.net.MalformedURLException, java.io.IOException

{
    return Drawable.createFromStream(((java.io.InputStream)new java.net.URL(url).awagetContent()), src_name);
}

Just pass the string url to the method(and for src_name any string ) and it will return you a drawable object, then use setBckgroundDrawable() method of the imageview to set the background of the image.
