Question

I need to rotate my image in my on touch listener when the user touches it. I am rotating a dial graphic, so it needs to rotate around its center point. Does anyone have an example?

Answer 1

I’d refer to the actual android documentation for animation here: http://developer.android.com/guide/topics/resources/animation-resource.html

As for setting up the rotation in an xml, it will look something like:

<set android:interpolator="@anim/linear_interpolator">
    <rotate 
       android:fromDegrees="180"
       android:toDegrees="0"
       android:pivotX="50%"
       android:pivotY="50%"
       android:repeatCount="0"
       android:duration="1000">
    </rotate>
</set>

That is for a 180 rotation.
