/**
|
|
* Since {@link FloatingActionButton} is possibly the worst widget supported by the framework, we
|
|
* need this class to work around several of it's bugs.
|
|
*
|
|
* <p>Current fixes:
|
|
*
|
|
* <ul>
|
|
* <li>Being able to trigger click events twice.
|
|
* <li>Banning setVisibility since 9 times out of 10, it just causes bad state.
|
|
* </ul>
|
|
*
|
|
* Planned fixes:
|
|
*
|
|
* <ul>
|
|
* <li>Animating on first show/hide
|
|
* <li>Being able to call show/hide rapidly and being in the proper state
|
|
* <li>Having a proper 48x48 touch target in mini mode
|
|
* </ul>
