RecyclerView: Set scroll position so that item appears at the bottom of the view

Question

I have a RecyclerView with a LinearLayoutManager that is backed by an adapter with items of different height. Is there a way to tell the RecyclerView to set the scroll position so that item X appears (more or less) exactly at the bottom of the screen?

I tried LinearLayoutManager.scrollToPosition() but this will position the item at the top of the view.

DIdn't scrollToPosition() work? Not sure about the bottom of the screen. — Malith Lakshan, May 24 '16 at 13:25
`scrollToPosition()` will position the item at the top of the view. I want the opposite. — Kirill Rakhman, May 24 '16 at 13:26

MyAdapter mAdapter;
RecyclerView recyclerView;
List<ItemData> data = new ArrayList<>();
LinearLayoutManager llm = new LinearLayoutManager(this);

try this in OnCreate method

recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(llm);
llm.setStackFromEnd(true);
mAdapter = new MyAdapter(data, getApplication());
recyclerView.setAdapter(mAdapter);

and when you insert an item try this

mAdapter.notifyItemInserted(data.size() - 1);
llm.scrollToPosition(data.size() - 1);

Try this in mainActivity.class

 rv_journey.setAdapter(ca);
            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    scrollList();
                }
            }, 500);

Here is my scroll Method

private void scrollList(){
        rv_journey.post(new Runnable() {
            @Override
            public void run() {
                // Call smooth scroll
                rv_journey.smoothScrollToPosition(Index);
            }
        });
    }

Set index from Adapter class which extend RecyclerView.Adapter Where You need to scroll...

if (Condition) {
                        mainActivity.Index=position+1;

                    }
                }

Happy Coding...
