    return mThumbIds.length;
}

            imageView = new ImageView(mContext);
            imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(8, 8, 8, 8);
            imageView.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Intent intent = new Intent(mContext,HeroData.class);
                    intent.putExtra("imageID", position);

You can keep your drawable resourses in another place, for example you can do it in resources, as string-array 

<resources>

<string-array name="thumbs_imgs">
    <item>@drawable/pic1</item>
    <item>@drawable/pic2</item>
    <item>@drawable/pic3</item>
</string-array>

</resources>

and then get by index drawable what you need

TypedArray imgs = getResources().obtainTypedArray(R.array.thumbs_imgs);
//get resourceid by index
mImgView1.setImageResource(imgs.getResourceId(i, -1));

Use Like this...

gridView.setOnItemClickListener(new OnItemClickListener()   
    {

        public void onItemClick(AdapterView<?> parent, View v,int position, long id) 

        {

            Intent i = new Intent(getApplicationContext(), HeroData.class);



            i.putExtra("imageID", position);

             startActivity(i);


        }
    });

Since you are sending resources, you can send the resource id instead of the index it has in the array. Something like this:

intent.putExtra("imageID", mThumbIds[position]);
mContext.startActivity(intent);

And in your activity:

Bundle bdl = getIntent().getExtras();
int imageRes = bdl.getInt("imageID");
ImageView image = (ImageView) findViewById(R.id.imageview);
image.setImageResource(imageRes);

Hope that helps.
