Implementation

Android Dial Picker, a circular custom view that works just like a rotating dial. DialView is highly customizable via xml or code. You can set direction(left,top,right,bottom), max/min ranges, interval values and colours. These custom attributes can be added and styled via XML as well as programatically.
As the dial rotates, the current value gets updated and is displayed on the screen.
