Question

I am trying to modify this example:

http://developer.android.com/resources/tutorials/views/hello-gridview.html

But instead of displaying images that are resources, I want to display Drawables that I currently am storing in a List.

Can anyone instruct me on how I would modify

 private Integer[] mThumbIds = {
         R.drawable.sample_2, R.drawable.sample_3,
         R.drawable.sample_4, R.drawable.sample_5,
         R.drawable.sample_6, R.drawable.sample_7,
         R.drawable.sample_0, R.drawable.sample_1,
         R.drawable.sample_2, R.drawable.sample_3,
         R.drawable.sample_4, R.drawable.sample_5,
         R.drawable.sample_6, R.drawable.sample_7,
         R.drawable.sample_0, R.drawable.sample_1,
         R.drawable.sample_2, R.drawable.sample_3,
         R.drawable.sample_4, R.drawable.sample_5,
         R.drawable.sample_6, R.drawable.sample_7
 };

To display my drawable items instead?

Thanks!

You only have to change a few minor things. In ‘imageView.setImageResource(mThumbIds[position]);’ you have to replace the array accessor by mThumbIds.get(position) and ‘mThumbIds.length’ becomes ‘mThumbIds.size()’.

This is untested, but I think that is all you need.
