val itemPositionToFocus = 0 // for example the first item
val viewHolder = mRecyclerView.findViewHolderForLayoutPosition(itemPositionToFocus)
viewHolder.itemView.requestFocus()

If you are looking for how to scroll to that 10th and 30th item then below solution is for you.

recyclerView.getLayoutManager().scrollToPosition(position)

Here position is, in which position you want to scroll.

For highlight that item you can change text format like bold or color of that item of recycler view.

If you want to highlight a certain items, then pass another arraylist containing ids to be highlighted to your adapter. And create a function usually through an interface that updates that list and reloads all the items in a different manner. and for scroll use smoothScrollToPosition(position).

You can use the RecyclerView directly for that.

Scroll to item:

  • with animation
recyclerView.smoothScrollToPosition(itemPosition)
  • without animation
recyclerView.scrollToPosition(itemPosition)
