Try this ::

This blog post has a good example on that. It shows you how to do the adapter: http://mihaifonoage.blogspot.com/2009/09/displaying-images-from-sd-card-in.html However I would be extending a CursorAdapter instead of a BaseAdapter.

To get the image from the specific folder refer this link.

Hope this helps you :)

i got it but in the second link it showing an error that cannot instantiate the type Image adapter in the line................adapter = new ImageAdapter(this, bmpArray, fileName); gridView = (GridView)findViewById(R.id.grid_view); gridView.setAdapter(adapter); – apcdgworks Jan 07 '13 at 06:56
Instead of "this",Pass the "YourActivityName.this". – AndroidLearner Jan 07 '13 at 07:00
