How to scroll to the bottom of a RecyclerView? scrollToPosition doesn't work

Question

I'd like to scroll to the bottom of the RecyclerView list after loading the activity.

GENERIC_MESSAGE_LIST = (ArrayList) intent.getExtras().getParcelableArrayList(ConversationsAdapter.EXTRA_MESSAGE);

conversationView = (RecyclerView) findViewById(R.id.list_messages);

conversationView.setHasFixedSize(true);

conversationViewLayoutManager = new LinearLayoutManager(this);

conversationView.setLayoutManager(conversationViewLayoutManager);

conversationViewAdapter = new ConversationAdapter(GENERIC_MESSAGE_LIST, this);

conversationView.setAdapter(conversationViewAdapter);

conversationView.scrollTo(...)

throws an exception about being not supported in RecyclerView, and

conversationView.scrollToPosition(...)

doesn't seem to do anything.

After the above block of code, I added

conversationView.scrollToPosition(GENERIC_MESSAGE_LIST.size() + 1)

which doesn't work. There are 30 elements in

GENERIC_MESSAGE_LIST

.

Answer 1

Just set setStackFromEnd=true or setReverseLayout=true so that LLM will layout items from end.

Sample:

final LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
linearLayoutManager.setReverseLayout(true);
_listView.setLayoutManager(linearLayoutManager);

See documentation for details.
