* Provide CheckBox for selected items
Newer API's highlight the background using the "activated" state. Older
APIs need this to be implemented differently, so there are now checkboxes
on the left of the list view items to provide this functionality.
* Clean up IDE warnings
Diamond operator for generics, remove unused imports and unused method.
* Adapter class created for installed apps
Cleaned up the code to do with binding views to the adapter in this view.
Previously it made quite a few assumptions about the structure of the layout,
e.g. "layout.getParent().getParent() is a LinearLayout", which would cause
crashes if the layout changed slightly.
* Cleaned up text alignment styles for API < 17.
API v17 has a textAlignment style, wherease previous verisons rely on
the "gravity" property. This change includes gravity="center" where there
was previously only textAlignment="center".
* Fragments get added properly on 2.3 device.
For some reason, when adding the fragment to android.R.id.content, it
wouldn't work on my 2.3 device. This change includes a (almost) empty
activity layout with a single FrameLayout. The fragments are added to
this rather than "content", and it works better. It is not perfect - it
still adds the fargments behind the action bar, and so the action bar
appears blue. But at least they are there :)
* Added translatable strings where constants were used before.
Not related to v2.3 support, but stil important for a stable release,
that is fully translated.
Bug in the code which decides which apps to select for swapping.
Due to the way in which Adapters and ListViews work together to provide
"header" and "footer" functionalities for lists, there is a mismatch between
the index in our original adapter, and the actual index on the list. It is
up to us to maintain this correctly, which was not done, hence the off by
one error.
This was present in the old local repo implementation, and the skeleton
code for implementing it was copied to the swap fragment. The only change
neccesary was to add a search button to the menu and make it have a
SearchView as its action view.
Shows an expandable notification on devices that support it (4.1+
I believe). The support library does most of the job of handling
incompatibilities between platforms.
