  <p>I want to open a new activity on thumb image onclick. It works fine when First Select item. If I click thumb image without selecting item it getting old value</p>
  
  <pre><code>Here is my updated listview adapter
   public View getView(int position, View convertView, ViewGroup parent) {
          View vi=convertView;
          if(convertView==null)
              vi = inflater.inflate(R.layout.list_item, null);
  
          TextView name = (TextView)vi.findViewById(R.id.name); // name
          TextView desc = (TextView)vi.findViewById(R.id.desciption); // collection
          TextView cost = (TextView)vi.findViewById(R.id.cost); // cost
          TextView category = (TextView)vi.findViewById(R.id.txtcategory); // cost
          TextView spec = (TextView)vi.findViewById(R.id.txtspec); // cost
          TextView largeimg = (TextView)vi.findViewById(R.id.txtlargeimage); // cost
  
          ImageView thumb_image=(ImageView)vi.findViewById(R.id.ivcatalouge); // thumb image
  
         thumb_image.setOnClickListener(new OnClickListener(){
  
          @Override
          public void onClick(View v) {
              // TODO Auto-generated method stub
  
              TextView c = (TextView) v.findViewById(R.id.txtlargeimage);
  
               Intent i=new Intent();
                  i.setClass(mCtx, FrmShowSingleImage.class);
                  i.putExtra("largeimage", c.getText());
                  mCtx.startActivity(i);
  
          }});
  
          HashMap&lt;String, String&gt; song = new HashMap&lt;String, String&gt;();
          song = data.get(position);
  
          // Setting all values in listview
          name.setText(song.get(FrmShowCatlogue.KEY_MODEL));
          desc.setText(song.get(FrmShowCatlogue.KEY_COLLECTION));
          cost.setText(song.get( FrmShowCatlogue.KEY_MRP));
          category.setText(song.get( FrmShowCatlogue.KEY_CATEGORY));
          spec.setText(song.get( FrmShowCatlogue.KEY_SPEC));
          largeimg.setText(song.get( FrmShowCatlogue.KEY_LARGE));
          largeimg.setVisibility(View.GONE);
                  try 
          {
              String filename=song.get(FrmShowCatlogue.KEY_IMAGES.toString());
              filename="thumbs/" + filename;
              // get input stream
              InputStream ims = mCtx.getAssets().open(filename);
              // load image as Drawable
              Drawable d = Drawable.createFromStream(ims, null);
              // set image to ImageView
              thumb_image.setImageDrawable(d);
          }
          catch(IOException ex) 
          {
  
              //thumb_image.setVisibility(View.GONE);
          }
  
          return vi;
      }

  <p>Now I am getting null pointer exception on thumb click.
  I have removed thumb_image onclick from SetOnItemClickListener of listview</p>
