@Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) { ... }
Drawable myIcon = getResources().getDrawable( R.drawable.button );
ColorFilter filter = new LightingColorFilter( Color.BLUE, Color.BLUE );
myIcon.setColorFilter(filter);

hop of those help? I have a gridview that has multi items (buttons) I bind background for each item in my adapter , You can set LayoutParams with fixed size to avoid resizing the view

around this issue If you have the two images already made, use a Button element in your GridView and set the Background element of your button to a state selector drawable. refer to this link for XML declarations on making your selector drawable example here . For your scenario you will have to create different selector XML files for each button.

I wish this help you I believe the issue is I was using a coordinator layout with the GridView. I have now seen prior posts explaining that the coordinator layout and Gridview dont work together. There were several workarounds presented but I could not figure out how to implement these with my particular project. I scrapped the coordinator layout and got the gridview to work properly. I did have an issue with trying to cast a uri to cursor in the cursor adapter which I changed to get it to work. I am still open to other solutions to get these to work together because the coordinator layout is smooth and more precise appearing.
