Alexander Doerflinger	d3912b3f16	Added GameSelection + Logic Now First screen is a game selection screen, second screen is the settings screen where characters, karts, etc can be found.	2017-08-18 14:18:09 +02:00
Alexander Doerflinger	e906031de4	Prepared usage of images (fully working with http-uri)	2017-08-17 16:17:47 +02:00
Alexander Doerflinger	4a6e8d9576	Changed VersionCode	2017-08-17 13:15:29 +02:00
Alexander Doerflinger	cdfb9a946d	Fixed an issue where only characters were writte to db Updates where not delivered / written into db. Problem was that onCheckedChangeListener did not fire. Now we simply switched the assigneing of ChangeListener andonClickListener and everything works fine.	2017-08-17 13:14:06 +02:00
Alexander Doerflinger	7f161a7442	Added Update functionality to toggle availability	2017-08-17 13:03:44 +02:00
Alexander Doerflinger	2b4515c284	Added CustomCursorAdapters for each PagerType Functional -> Still update and toggle availability need to be implemented.	2017-08-17 12:28:36 +02:00
Alexander Doerflinger	a9fa61bac4	Reached Clean State, NO FUNCTIONALITY ADDED Only applied some checkstyle and reformated code. Also modified some warnings	2017-08-17 11:07:25 +02:00
Alexander Doerflinger	2ffb854927	Fully Functional Database loading Adapter needs to be replaced with custom adapter. Click needs to be implemented as well.	2017-08-16 16:20:52 +02:00
Alexander Doerflinger	8bf84bf936	Backup for local changes	2017-08-16 12:48:58 +02:00
Alexander Doerflinger	a25a12b8c7	[INTERMEDIATE STATE] Pager implementation started Seems not to work at all. We need to have a further look into this. At least it is somehow not crashing anymore...	2017-08-10 16:54:55 +02:00
Alexander Doerflinger	9494c081d1	Added Generic and Specific Fragments Generic Fragment Layout was defined Specific Laout Object wer integrated including all object specific handling FragmentObjects can now be added to ListViews. Possible clean solution would be to have a PagingAdapter for each object type.	2017-08-10 10:11:29 +02:00
Alexander Doerflinger	8967107045	Fixed some general warnings.	2017-08-09 16:24:19 +02:00
Alexander Doerflinger	8e5791d35e	Added support for game and onlyAvailable when retireving data From now on, it is possible for the API to retrieve only object which are assigned to a specific game or only objects that are available or both. This might (pretty sure it is) needed in the future	2017-08-09 16:18:33 +02:00
Alexander Doerflinger	05076a01f1	Added "GetAll" Functions to Database handler These functions return all items of a single kind. We need to think of if we should handle more logic within sqlite queries (eg. more specific like get all characters of this game) or if we would like to handle this on apps side.	2017-08-09 15:28:22 +02:00
