Question

in my app i am trying to form a grid view from the xml file that been stored in web.

Following is my code

grid = (GridView)findViewById(R.id.gridView1);
imageXMLfn();
grid.setAdapter(new ImageAdapter(this));

private void imageXMLfn() 
    {
        try
        {
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            factory.setIgnoringComments(true);
            factory.setCoalescing(true); 
            factory.setNamespaceAware(false); 
            factory.setValidating(false);

            DocumentBuilder parser = factory.newDocumentBuilder();             
            URL url = new URL(UserManual.IMAGE_URL);
            Log.e("ViewImage3",""+UserManual.IMAGE_URL);

            Document document= parser.parse(new InputSource(url.openStream()));            
            NodeList sections = document.getElementsByTagName("application");
            numSections = sections.getLength();
            for (int i = 0; i < numSections; i++) 
            {
                Element section = (Element) sections.item(i); 
                if(section.hasChildNodes()==true)
                {
                    NodeList section1=section.getChildNodes();
                    for(int j=0;j<section1.getLength();j++)
                    {
                        if(section1.item(j).hasChildNodes()==true)
                        {
                             for(int k=0;k<section1.item(j).getChildNodes().getLength();k++)
                             {                  
                                 xmlvalue=String.valueOf(section1.item(j).getChildNodes().item(k).getNodeValue()).trim(); 
                                 arl.add(xmlvalue);
                             }
                         }
                     }
                  }
               }
            } 
            catch(Exception e)
            {   
                System.out.println(e);
                Log.e("ViewImage Error1",e.getMessage());
            }

            Iterator<String> itr = arl.listIterator();
            int z=0,x=0,increment=0;
              while (itr.hasNext()) 
              {
                id = itr.next();
                img = img+id;
                z++;
              }           
    }


public class ImageAdapter extends BaseAdapter 
    {
        private Context myContext;

        private String[] myRemoteImages = {id};

        public ImageAdapter(Context c)
        { 
            this.myContext = c; 
        }
}

Either i am getting only the first image stored in that url or else i am not getting any other images

Following is the link from which i am trying to get the images

Your code is not complete, so it’s a bit difficult to give a definite answer but in the while loop at the end if imageXMLfn you’re assigning id = it.next(). The image adapter than uses only id which is set to the last value in the iterator. Supposing that arl is a field in your class of type ArrayList<String> it probably can be solved by:

public class ImageAdapter extends BaseAdapter 
{
    private Context myContext;

    private String[] myRemoteImages = arl.toArray(new String[arl.size()]);

    public ImageAdapter(Context c)
    { 
        this.myContext = c; 
    }
}

However, your code is really incomplete in this regard, so I’m not sure whether this will work out.
