According to this link:

The rotation speed of the indeterminate progress bar is fixed at one revolution every 4 seconds, changing the duration attribute in the drawable XML has no effect. If you prefer to speed it up, you can change the toDegrees attribute to multiples of 360:

  • 720 makes one turn in 2 seconds
  • 1080 makes one turn in 1.33 seconds
  • 1440 makes one turn in 1 second

In addition, you can just use indeterminateDuration for the ProgressBar.

Setting duration and/or repeat count did not help me with an indeterminate ProgressBar animation. I had to increase the toDegrees to have it make additional loops:

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:drawable="@drawable/ic_indeterminate_progress"
    android:duration="1"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="1080" /> <!--1080 is 3 loops instead of 1 in same amt of time-->

Set the duration and repeatCount that you want the animation to run.
