Implement ViewPager2 to swipe on the Current Played Track/ Album Cover

[heinrich27]

Hi,

I'd suggest to integrate/use the Androidx ViewPager2 View in the player screen for the Album Cover and the Currently Played Track in the Navbar. Why? This allows a more smooth Navigation between Songs (Next & Previous) and also supports Swiping. You can also make a nicer transition when a new song is played.

Examples from my Test App:




Whats the ViewPager2?
Thats Androids Carousel View/Widget, that allows to display a "list" of ViewHolders/Layouts. Its implemented pretty similar to how ListViews are created.

Some notes about Implementing the ViewPager2: (i used it in a Player I've been working on)
- The ViewPager2s Listener has to respect a couple conditions inside the OnPageSelected Method:
   - call the Skip Method/Play Method only when the User swiped. (I have a boolean that is set to true when the Pagers page is updated from Code, because a new song is played etc., and set to false in the OnPageSelected, and Skip/Play/Prev is only called if that boolean was false)
   - the adapter might just take a similar dataset as the Playlist Views.

ViewPager2 is useless, the bottleneck is track loading performance, player cannot load tracks and its album arts fastly.
