Setting Custom Adapters To Grid Views

In my main activity I have a spinner which contains three categories(All,Horizontal and Vertical), below that there is a gridView. I have some images in resource folder which are f

Solution 1:

You don't need three gridViews and three adapters. One is enough. When changing category from spinner , refresh the list allid, vid, hid (used in Adapter to display gridview) and then notifyDataSetChanged() on the adapter.

EDIT: try this:
