Problems with D-pad navigation

[joharei]

I'm using the library in an Android TV app, so navigation with D-pad is a requirement for me. When I press down in a list, the focusing works correctly until I reach the last displayed row. Pressing down from there does nothing, and onFocusSearchFailed() is called in the layout manager.

I've worked around this by subclassing the layout manager and scrolling a little when the focus search fails:

override fun onFocusSearchFailed(focused: View, focusDirection: Int,
                                 recycler: RecyclerView.Recycler, state: RecyclerView.State): View? {
    // Need to be called in order to layout new row
    scrollVerticallyBy(when (focusDirection) {
        View.FOCUS_DOWN -> 10
        View.FOCUS_UP -> -10
        else -> 0
    }, recycler, state)

    return super.onFocusSearchFailed(focused, focusDirection, recycler, state)
}

But there is probably a better way to do this.

Thanks for the nice library!
