NumberProgressBar

I decided to do this because I was really tired of android original progress bar. So, I made some change, added more color style for this. And also you can contribute more color style, or new idea to me. I made some predesign style. You can use them via style property. You can get more beautiful color from kular, and you can also contribute your color style to NumberProgressBar! There are several attributes you can set, the reached area and unreached area, the text area, the bar, and the distance between reached area and unreached area.
