android - Is there a RecyclerView equivalent to ListView's transcriptMode alwaysScroll?

Question

With ListView, I could easily implement an auto-scrolling chat view by setting:

android:transcriptMode="alwaysScroll"

in its XML. Is there an equivalent in RecyclerView?

Answer 1

RecyclerView doesn't seem to have that option. You have to manually scroll. Do something like....

notifyItemInserted(int posn);
recyclerView.smoothScrollToPosition(la.getItemCount()); // <= use this.

Also void notifyItemInserted(int posn); is final. So you can't Override that to always scroll there either.

You need to make a method where you can call something similar to the above code as bundles.

Also keep in mind smooth scroll is kinda buggy. If you have many elements(e.g. 1000 elements) and you want to scroll a long distance, the scroll takes forever. There's a tutorial I found that addresses this issue and explains how you can fix that. http://blog.stylingandroid.com/scrolling-recyclerview-part-1/
