    <p>Just some points regarding your code:</p> <p>You're probably getting only the first item with an overlay because you search with <code>findViewById</code> on the parent, the <code>GridView</code> and not the row view <code>view</code>, so <code>findViewById</code> will return the first <code>ImageView</code> that it finds(which is on the first visible row). In order to show that overlay you have some options on how to do it depending on the code that you used in the adapter's <code>getView</code> methodif you want to only show one item with an overlay at the time(for example, when you click one item, the previous one that was clicked(if any) will deselect) or if you have the options to toggle the item(click-> overlay, another click -> without overlay). Without knowing the information above this is how I would do it:</p> <pre><code>public void onItemClick (AdapterView&lt;?&gt; parent, View view, int position, long id) { ImageView overlay = (ImageView) view.findViewById(R.id.ItemOverlayImage); if (!items.get(position).isSelected()) { // the item doesn't have an overlay overlay.setImageResource(R.drawable.overlay); // set the overlay items.setSelected(true); // set to true so the adapter knows it } else { // the item has the overlay so we remove it overlay.setImageResource(0); items.setSelected(false); set to false so the adapter knows it } } </code></pre> <p>So long as you use in the <code>getView</code> method the <code>isSelected</code> to set or not set the overlay you'll be ok. </p> <p>Also you should remove the <code>FrameLayout</code> that wraps the <code>RelativeLayout</code>, as you don't do anything with it(?!?).</p>

    1. COThanks, as soon as I started using the view and not the parent it worked just fine. I also removed the FrameLayout and the overlay looked find as well. I thought a FrameLayout was going to be necessary to stack the images on top of each other.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
