    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-->

    add in code to progress.xml

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

    add in code to progress.xml

    <?xml version="1.0" encoding="utf-8"?>
        <rotate xmlns:android="http://schemas.android.com/apk/res/android"
            android:pivotX="50%"
            android:pivotY="50%"
            android:fromDegrees="0"
            android:toDegrees="1440">
        
            <shape
                android:shape="ring"
                android:innerRadiusRatio="3"
                android:thicknessRatio="8"
                android:useLevel="false">
        
                <size
                    android:width="76dip"
                    android:height="76dip" />
        
                <gradient
                    android:type="sweep"
                    android:useLevel="false"
                    android:startColor="#FF0000"
                    android:endColor="#00ffffff"
                    android:angle="0"/>
        
            </shape>
        
        </rotate>

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

    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.
