How to scroll horizontal RecyclerView programmatically?

Question

I have a horizontal RecyclerView and two button (Next,Previous) as shown in the image below.

so i need to move to the next item or position by use these buttons , i know about method called scrollTo but i don't know how does it work

Answer 1

I found the answer:

case R.id.next:
    mRecyclerView.getLayoutManager().scrollToPosition(linearLayoutManager.findLastVisibleItemPosition() + 1);
    break;
case R.id.pre:
    mRecyclerView.getLayoutManager().scrollToPosition(linearLayoutManager.findFirstVisibleItemPosition() - 1);
    break;

Answer 2

RecyclerViews have a methods which they expose for scrolling to a certain position:

Snap scroll to a given position:

mRecyclerView.scrollToPosition(int position)

Smooth scroll to a given position:

mRecyclerView.smoothScrollToPosition(int position)

For these methods to work, the LayoutManager of the RecyclerView needs to have implemented these methods, and LinearLayoutManager does implement these in a basic manner, so you should be good to go.
