android - AndroidTV raw particular focusing

Question

I have the next UI:

When user uses D-pad in recyclerview I want to focus "Part 1" by default and if button down pressed. But if user pressed button right when current focus is in "Part 1" focus must be changed to "Part 2" (and to "Part 1" if left arrow button pressed and current focus is in Part 2).

My current logic is default - when clicking button down all item / adapter raw is focused.

</LinearLayout>

What should I change to achieve expected result?

I've tried some combinations of

android:focusableInTouchMode=""
android:focusable=""

but with no result.

</LinearLayout>

But still all LinearLayout "LL"(all raw) is selected (instead of only "LLPart1"). Right and left arrows do nothing.

Use requestFocus for default focused view and use nextFocusUp/Down/Left/Right for each view
