exoPlayer controls using keyboard & dpad

[shaunsantacruz]

Current behavior

Android exoplayer controls are not focusable using a keyboard or dpad directional inputs.

Note: Pressing pause/play on a remote does cause the control panel to focus on the play/pause button, which you can then use the left/right to focus other control items, but there's no state_focused feedback for which imagebutton is currently focused.

Reproduction steps

Using a keyboard or dpad, pressing down does not show the control panel.

Expected behavior

Using a keyboard or dpad, pressing down shows the control panel and focuses on the play/pause button. Once the play/pause is focused, pressing left/right focuses the other control items with some sort of visual feedback. I suggest an opacity change maybe?

Could someone please take a look? It seems like a quick enhancement. I looked into fixing it myself but it would be better left to someone with knowledge of best practices. Thanks!
