When you return a boolean in an event handler method, it determines whether the event is consumed or not.

• If you return true from an ACTION_DOWN event, you are interested in the rest of the events in that gesture. A "gesture" in this case means all events until the final ACTION_UP or ACTION_CANCEL.
• If you return false from an ACTION_DOWN, you do not want the event and other views will have the opportunity to handle it. If you have overlapping views this can be a sibling view. If not it will bubble up to the parent.

In general,

• Any time you return true you tell Android that you want to keep consuming the Gesture
• Any time you return false you tell Android to give another View the opportunity to handle the event.

HOWEVER, none of this applies to a ListView. For a list view, you need to call super.onTouch
