Java – Android TV RecyclerView sets the next focus of its project

I

work on android TV, I have two Horizontal Recyclerviews in our fragment, it scrolls well when I scroll the first Recyclerview to the right using D-pad, and when I reach the last focus item of its Recycler View, the autofocus drops to the second Recycler View item.

How can this be prevented?

It may be late, but for anyone still looking for a solution:

You should write your own logic when searching for the next focus, if the last View is provided as the next focus item at the end of the list, or you can modify the logic as needed. For example:

override fun onInterceptFocusSearch(focused: View?, direction: Int): View? {
    val position = getPosition(focused)
    val count = itemCount
    lastKnownPosition = position
    return if (position == count - 1 && direction == View.FOCUS_RIGHT) {
        focused
    } else {
        super.onInterceptFocusSearch(focused, direction)
    }
}

And this method becomes part of the layout manager.
