Create a new selector (see 
http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList)
for the item, and then configuring the colour/background values
depending on state. By state, I mean, your item could be
'Checkable' (i.e. only a single item in the whole GridView can be
checked at a time) and then when it's tapped, set it to checked, and
the appropriate value in the selector would be chosen. Alternatively,
you could use the item's .setEnabled() method and do something
similar.

You may also need to be aware of the android:duplicateParentState
attribute.
