    Hi Guys,
    I am working on an app that connects with a device via bluetooth and receives data in terms for Hexadecimal and converts it. I have to display this converted data in the app in terms of an traditional Ammeter, the one with amperes as measures and a red shifting/moving hand.
    So please help me how can I create or get this kind of Ammeter ?

    Thanks,
    Vishal

    With a graphics program - maybe something like Paint.net. there's no "meter" you can call in Android, you have to design it yourself. (Whether you use software to display a single picture of a pointer at different angles, or keep a few hundred pictures of pointers at different angles, and display the correct one for the moment, is up to you. Many pointers is easier, but a lot more data, calculating the display for a given value is more code, but just enough data for one pointer. Or you could even use code to display a red or black line, and not use a graphic for the pointer at all.)
