GridView with images from xml file in the web

I'm trying to show some images which URLs are in an XML file that you can find it on the web. I've tried the gridview and it worked, I've tried to show an image from the XML file and it worked, but when I put both together, it doesn't work!! I don't know the reason. Any help please?

The code is:

package com.examples.xmlparser;

import java.io.InputStream;
import java.net.URL;
import java.util.List;

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

               ImageView imgView =(ImageView)findViewById(R.id.ImageView01);

                       /* Get the XMLReader of the SAXParser we created. */
                       XMLReader xr = sp.getXMLReader();

                       ExampleHandler myExampleHandler = new ExampleHandler();
                       xr.setContentHandler(myExampleHandler);

                       /* Parse the xml-data from our URL. */
                       xr.parse(new InputSource(url.openStream()));
                       /* Parsing has finished. */

                       /* Our ExampleHandler now provides the parsed data to us. */
                       ParsedExampleDataSet parsedExampleDataSet =  myExampleHandler.getParsedData();

                       listPicName=parsedExampleDataSet.getlistPicName();
                       /* Set the result to be displayed in our GUI. */
                //       tv.setText(parsedExampleDataSet.toString());

                       }


                     //  imgView.setImageDrawable(LoadImageFromWebOperations(10));
                       GridView gridview = (GridView) findViewById(R.id.gridview);
                       gridview.setAdapter(new ImageAdapter(this));

               } catch (Exception e) {

                     //  tv.setText("Error: " + e.getMessage());

       public class ImageAdapter extends BaseAdapter {
         private Context mContext;

         public ImageAdapter(Context c) {
             mContext = c;
         }

         public int getCount() {
             return 0; //mThumbIds.length;
         }

         public Object getItem(int position) {
             return null;
         }

         public long getItemId(int position) {
             return 0;
         }


         // create a new ImageView for each item referenced by the Adapter
         public View getView(int position, View convertView, ViewGroup parent) {
             ImageView imageView;
                if (convertView == null) {  // if it's not recycled, initialize some attributes
                    imageView = new ImageView(mContext);
                    imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
                    imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
                    imageView.setPadding(8, 8, 8, 8);
                } else {
                    imageView = (ImageView) convertView;
                }
                //imageView.setImageResource(mThumbIds[position]);
                //Drawable d=LoadImageFromWebOperations(position);
                imageView.setImageDrawable(pictures.get(position));
                //Drawable d=LoadImageFromWebOperations(position);
                //imageView.setBackgroundDrawable(d); 
             return imageView;
         }


     }




       private Drawable LoadImageFromWebOperations(int position)
    {
        String path=("http://94.23.207.167/websiteIphone/Admin/content/Santa/Santa/3_1.jpg");
     //   path=path.concat(listPicName.get(position));

           Toast.makeText(XMLParser.this, "" +path, Toast.LENGTH_LONG).show();
           Log.w("MIERDA","MIERDA");

         try{
             InputStream is = (InputStream) new URL(path).getContent();
             Drawable d = Drawable.createFromStream(is, "src name");
             Log.w("CREADO","CREADO");
             return d;
         }catch (Exception e) {
             System.out.println("Exc="+e);
             return null;
         }
  }


}

The XML file is:

GridView xmlns:android="http://schemas.android.com/apk/res/android" 

    android:id="@+id/gridview"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:columnWidth="90dp"

    android:numColumns="auto_fit"

    android:verticalSpacing="10dp"

    android:horizontalSpacing="10dp"

    android:stretchMode="columnWidth"

    android:gravity="center"

/>

I think, you have to replace your code :

public int getCount() {
             return 0; //mThumbIds.length;
         }

with this code :

public int getCount() { 
    return pictures.size(); 

        } 

Because, as the size of the pictures(List) is zero in your code, the remaining part of your code will not get executed.
