I want to scroll to the bottom of a recycler view on click of a button, how do I do this?
回答1:
You have to make use of LayoutManager for that. Follow the below steps.
1). First of all, declare LayoutManager in your Activity/Fragment. For example, I have taken LinearLayoutManager
private LinearLayoutManager mLinearLayoutManager;
2). Initialise the LinearLayoutManager and set that to your RecyclerView
mLinearLayoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(mLinearLayoutManager);
3). On your Button onClick, do this to scroll to the bottom of your RecyclerView.
mLinearLayoutManager.scrollToPosition(yourList.size() - 1); // yourList is the ArrayList that you are passing to your RecyclerView Adapter.
Hope this will help..!!

You can use scrollToPosition() with the index of the last position.
