| 18 | For list items that contain secondary actions (in this case, 'delete'), |
| 19 | it's important to use dividers to distinguish the primary touch target from |
| 20 | the secondary action. This is done using android:showDividers and its |
| 21 | related attributes. |
| 22 | |
| 23 | The android:dividerPadding attribute insets the divider line by the given |
| 24 | amount on each side (in this case, top and bottom). Divider padding helps |
| 25 | establish visual hierarchy when several dividers are used in a screen. In |
| 26 | this case, the padding helps separate this vertical divider from horizontal |
| 27 | list item separators in the main ListView, and establishes a stronger |
| 28 | relationship between the delete action and the primary target to its left. |

| 40 | Any view or view group can become interactive by simply setting the |
| 41 | android:clickable and android:focusable attributes to true. |
| 42 | |
| 43 | When doing this, make sure to provide adequate touch feedback by also |
| 44 | setting the view background to ?android:selectableItemBackground. When |
| 45 | using the Holo theme, this drawable is transparent by default, but |
| 46 | changes to a translucent color overlay when the view is pressed or |
| 47 | focused. |

| 76 | When using the Holo theme, setting a Button or ImageButton to |
| 77 | ?android:borderlessButtonStyle removes its border and sets the |
