Video descriptions can be very long. Some of them are
basically walls of text with couple of lines at top or bottom.
They are also not scrolled within TextView itself, - instead
NewPipe expects user to scroll their containing ViewGroup.
This renders all builtin MovementMethod implementations useless.
This commit adds a new MovementMethod, that uses requestRectangleOnScreen
to intelligently re-position the TextView within it's scrollable container.
* Move all focus-related work arouns to NewPipeRecyclerView
* Try to pass focus within closer parents first
* Do small arrow scroll if there are not more focusables in move direction
FocusFinder has glitches when some of target Views have different size.
Fortunately LayoutManager can redefine focus search strategy to override
the default behavior.
* Hide player controls when back is pressed (only on TV devices)
* Do not hide control after click unless in touch mode
* Show player controls on dpad usage
* Notably increase control hide timeout when not in touch mode
GridLayoutManager is buggy - https://issuetracker.google.com/issues/37067220:
it randomly loses or incorrectly assigns focus when being scrolled via
direction-based navigation. This commit reimplements onFocusSearchFailed()
on top of scrollBy() to work around that problem.
Ordinary touch-based navigation should not be affected.
