RecyclerView stackFromBottom
Making it a little explicit:
final LinearLayoutManager layoutManager = new LinearLayoutManager(mActivity); layoutManager.setStackFromEnd(true); recyclerView.setLayoutManager(layoutManager);
Thanks to tyczj's comment I figured it out. In RecyclerView instead of stackFromBottom you have to use stackFromEnd https://developer.android.com/reference/android/support/v7/widget/LinearLayoutManager.html#setStackFromEnd(boolean)
