Android: How to compare resource of an image with R.drawable.imagename?

Question

I am working on a sample application in which I need to get the resource of an image view in a onClick listener and compare that with the image source that I know exists. If the resources are the same, I want to launch another intent. The problem I am facing right now is to access that ImageView (and hence its resource Id integer) to compare to the drawable resource.

@Override
// should int be final ??
public View getView(final 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.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) { 
// This is not working and I need to find a way to solve this >>
                if (((ImageView)v).getResources().getInteger(0) == R.drawable.imageToCompare)
                {
                    // do nothing
                }
                else
                {
                    // do something         
                }

You can't get a drawable id from an ImageView. But if you set it from code, you can also store it somewhere, for example in the tag field. Take a look at the similar question: Who I compare an background Image resource TextView with a R.drawable.bg_image for switch.
