Question

I am working on an app in which i have to spin a object like in “Spin The Bottle” app.

Rotation has been started using RotateAnimation but problem is that is stops every time at same position. I want to stop it randomly. Please help me.

Thanks in Advance

How are you calling the function?

The documentation here: http://developer.android.com/reference/android/view/animation/RotateAnimation.html

shows a few different constructors… one taking a start angle and a stop angle. All you need to do is use a random number function to generate the stop angle and pass that in:

    RotateAnimation(0, randomNumber);

Of course if you want it to start from the previous position you just need to keep that number in a separate variable and pass it in as the first parameter.
