get visible item in RecyclerView

Question

How can I get a current item in RecycerView? In my use-case RV item takes all screen space, so there is only one item at a time. I've tried to google before, but nothing helpful was found.

The whole use case:

1. UI. The bottom navigation has a button that should call a certain method (let's say a foo() method) in fragment

2. this foo() method should get a visible item from the adapter and call a specific method in a presenter.

Answer 1

use this in your code

    LinearLayoutManager mLayoutManager;
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);

and get your visible item using below code

mLayoutManager.findFirstVisibleItemPosition();

Answer 2

You could also use an OnItemClickListener on your RecyclerView's ListAdapter to determine the current item. In that case the item needs to be clicked though.
