* This is not sufficient for switching between fragments. So instead we make
* the content part of the tab host 0dp high (it is not shown) and the
* TabManager supplies its own dummy view to show as the tab content. It listens
* to changes in tabs, and takes care of switch to the correct fragment shown in
* a separate content area whenever the selected tab changes.
