The LoyaltyCardEditActivity assumes on many places that an empty string
means it doesn't know a value yet. This patch ensures that the
BarcodeSelectorActivity returns a special string so that the
LoyaltyCardEditActivity can distinguish explicitly picking no barcode
from a not yet populated field.
This is mostly the work of Android Studio's
Refactor > Migrate to AndroidX...
option. That mostly worked. The two places which were manually updated
were:
- The reference to AppBarLayout$ScrollingViewBehavior in
loyalty_card_edit_activity.xml
- The suggested constraintlayout version, 2.0.0-beta4 caused build
issues that 1.1.3 avoids
This adds config options for the colors used for the store text
and background when displaying the store name in the single
card view or the thumbnail for the card list.
This changes the layout when viewing a single card. The new layout
will have a colored area at the top which displays the first letter
of the company, and after that the barcode. The note will be displayed
on the card list screen and is presently omitted here.
As this layout is experimental, the layout for editing a card is
not yet updated. To achieve this the card viewing activity is split
into two separate classes, where one handles viewing and one handles
editing. When the view layout finalizes the edit icon can be updated
as time allows.
