Vertical (rotated) label in Android

Question

I need 2 ways of showing vertical label in Android:

1. Horizontal label turned 90 degrees counterclockwise (letters on the side)
2. Horizontal label with l

Answer 1

Tried both of the VerticalTextView classes in the approved answer, and they worked reasonably well.

But no matter what I tried, I was unable to position those VerticalTextViews in the center of the containing layout (a RelativeLayout which is part of an item inflated for a RecyclerView).

FWIW, after looking around, I found yoog568's VerticalTextView class on GitHub:

https://github.com/yoog568/VerticalTextView/blob/master/src/com/yoog/widget/VerticalTextView.java

which I was able to position as desired. You also need to include the following attributes definition in your project:
