I’m using a RotateAnimation to rotate an image that I’m using as a custom cyclical spinner in Android. Here’s my rotate_indefinitely.xml file, which I placed in res/anim/:
<?xml version="1.0" encoding="UTF-8"?>
<rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:repeatCount="infinite"
android:duration="1200" />
When I apply this to my ImageView using AndroidUtils.loadAnimation(), it works great!
spinner.startAnimation(
AnimationUtils.loadAnimation(activity, R.anim.rotate_indefinitely) );
The one problem is that the image rotation seems to pause at the top of every cycle.
In other words, the image rotates 360 degrees, pauses briefly, then rotates 360 degrees again, etc.
I suspect that the problem is that the animation is using a default interpolator like android:iterpolator="@android:anim/accelerate_interpolator" (AccelerateInterpolator), but I don’t know how to tell it not to interpolate the animation.
How can I turn off interpolation (if that is indeed the problem) to make my animation cycle smoothly?
