Answer 1

Use Space Decoration Class For That

public class SpacesItemDecoration extends RecyclerView.ItemDecoration {
    private int space;

    public SpacesItemDecoration(int space) {
        this.space = space;
    }

    @Override
    public void getItemOffsets(Rect outRect, View view,
                               RecyclerView parent, RecyclerView.State state) {
        outRect.left = space;
        outRect.right = space;
        outRect.bottom = space;

        // Add top margin only for the first item to avoid double space between items
        if (parent.getChildLayoutPosition(view) == 0) {
            outRect.top = space;
        } else {
            outRect.top = 0;
        }
    }
}

Your Activity Where You Set Your Adapter

int spacing = getResources().getDimensionPixelSize(R.dimen.spacing);

  recyclerview.addItemDecoration(new SpacesItemDecoration(spacing));

Specify in dimen.xml
