Shift recyclerview focus to last element in the list

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.

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 simply use below code. Here recyclerView.getBottom() defines the position to be focus

recyclerView.smoothScrollToPosition(recyclerView.getBottom());

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);

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" />

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 .

use recyclerView.smoothScrollToPosition(position);

position is your index of last item inserted. This will move your the RecyclerView focus on the last element.

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);
