How to make a custom progressbar in Android?

Question

What would be the best way to make somthing looking like this:

The text on it needs to be customizable, not only numbers, some strings too, depending on context.

From what I see it:

1. Create a custom View and within onDraw perform all the calculations and text alignment.
2. Style or extend a horizontal ProgressBar.

What do you think ?

Answer 1

Extend ProgressBar ... override onDraw()

The primary reason for this is that all of the primary methods are already there and the first rule of object-orientated programming is code-reuse means don't reinvent the wheel.
