Took a while to figure out, but the problem was that the support
libraries ListFragment would only ever use getActivity() when
creating widgets. What we really needed was the ability to use
an alternative context, namely a ContextThemeWrapper. If this is
passed to the constructor of a widget, it is themed appropriately.
To make it work, we now create our own list view in onCreateView()
(which is really a copy of the code from the android list_content.xml
file anyway). There are also some workarounds for a bug in the
support library with regards to using your own view.
The back button will take you back through each step of the swap
process now, and remove the swap Activity completely if you press
back from the first screen. Also, when the WiFi QR code is shown,
the local repo manager actually starts the relevant service.
The Fragments and an Activity which tie all of the swap views together
has begun. The first bit of implementation is to get the current
wifi network displayed, which worked out alright.
This commit contains a lot of theme related stuff, particularly
involving taking assets from carries mockups and making them suitable
to use as drawables. The process for doing this is a story for another
day, but I'll document it and put it on the wiki in the future. carrie
showed me a script that a mate of hers used on another project, and
I've adapted it a little to make it work nicely here (note - it isn't
in this commit).
The button is blue, and always shown with associated text in the
ActionBar. This required a custom drawable which was set as the
background in the styles.xml.
