match_parent width does not work in RecyclerView

Question

My RecyclerView and item has match_parent width but the result is :

Answer 1

I was using a FrameLayout with MATCH_PARENT for width and was seeing the same behavior with a RecyclerView + LinearLayoutManager. None of the above changes worked for me until I did the following in the onCreateViewHolder callback:

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    // create a new view
    View v = LayoutInflater.from(parent.getContext())
                           .inflate(R.layout.note_layout, parent, false);
    v.setLayoutParams(new RecyclerView.LayoutParams(
          ((RecyclerView) parent).getLayoutManager().getWidth(),
          context.getResources()
                 .getDimensionPixelSize(R.dimen.note_item_height)));

    return new ViewHolder(v);
}

Clearly looks like a bug in (I'm guessing) the RecyclerView implementation.
