@Override
public void onClick(View v) {
// TODO Auto-generated method stub
try{
imageUrls=strimgview.get(pos).split("\\|\\|");
i=imageUrls.length;
if((i<=1))
{
i++;
ImageView imageView =(ImageView) v.findViewById(R.id.npTupleImage);
imageView.setBackgroundResource(R.drawable.logo);
// imageLoader.displayImage(imageUrls[i], imageView, options);
// Log.d("imageUrlnew ",imageUrls[i]);
Log.d("imageUrlnew ",i+" "+imageUrls.length);
}
}
catch(Exception e)
