Shift recyclerview focus to last element in the list

Question

I am using recyclerview to display messages in a chat window. However, when a new message is being edited, the recycler view focus should be on the last element. I expect there would be some way to shift the focus of a recyclerview to last element instead of first.

Answer 2

Use can add any of the two lines on your LinearLayoutManager object to scroll your recyclerview to the bottom ...

llm.setStackFromEnd(true);

OR

llm.setReverseLayout(true);

Answer 3

Use

recyclerView.smoothScrollToPosition(position)
adapter.notifyDataSetChanged();

where position is the index of last element

recyclerView.getAdapter().getItemCount()-1

use this to get last element.

This worked for me .

Answer 4

There are 2 ways by which you can do.

1: When you are creating any LayoutManager for the RecyclerView, Make the last parameter in its constructor as true.

LinearLayoutManager layoutManager = new LinearLayoutManager(MainActivity.this,LinearLayoutManager.HORIZONTAL,true);

2: Simply tell the RecyclerView to scroll to the last position.

recyclerView.smoothScrollToPosition(lastPosition);

Answer 5

use layoutManager.setStackFromEnd(true); instead of this.

Sample

    LinearLayoutManager layoutManager = new LinearLayoutManager(this);
    RecyclerView recyclerView = findViewById(R.id.list);
    layoutManager.setStackFromEnd(true);
    recyclerView.setLayoutManager(layoutManager);

You can use app:stackFromEnd="true" in your recycler view XML code like:

 <android.support.v7.widget.RecyclerView
  android:id="@+id/message_list"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:layout_above="@id/message_input"
  android:layout_alignParentTop="true"
  app:stackFromEnd="true" />
