    <p>By default, <code>ListView</code> has a <code>Selector</code> that will play a <code>TransitionDrawable</code> when you longpress a list item. However, if your list item view has a solid background, then you won't be able to see the selector's longpress animation (or on any other states) , because it's covered up by the list item's background.</p> <p>If you want to see the selector's longpress animation/selected/pressed state, then the list item's has to have a transparent background when the item is selected/pressed/longpressed. You can do it by using a <a href="http://developer.android.com/reference/android/graphics/drawable/StateListDrawable.html">StateListDrawable</a> as your item's background instead of a solid color.</p> <p>Here is a sample of <a href="http://developer.android.com/reference/android/graphics/drawable/StateListDrawable.html">StateListDrawable</a> for that purpose:</p> <pre><code>public class ColorfulListItemDrawable extends StateListDrawable { private final PaintDrawable mColor; public ColorfulListItemDrawable(int color) { mColor = new PaintDrawable(color); initialize(); } private void initialize() { Drawable color = mColor; Drawable selected = new ColorDrawable(Color.TRANSPARENT); addState(new int[] {android.R.attr.state_pressed, android.R.attr.state_enabled, android.R.attr.state_window_focused}, selected); addState(new int[] {android.R.attr.state_pressed, android.R.attr.state_enabled, android.R.attr.state_window_focused,android.R.attr.state_selected}, selected); addState(new int[] {android.R.attr.state_enabled,android.R.attr.state_window_focused, android.R.attr.state_selected}, selected); addState(new int[] {}, color); } public void setColor(int color) { mColor.getPaint().setColor(color); mColor.invalidateSelf(); } } </code></pre>

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.
