android:indeterminateDrawableThe value is @android:drawable/progress_medium_white , locate the Progress_medium_white.xml in the drawable directory, open

<?xml version="1.0" encoding="utf-8"?><animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"    android:drawable="@drawable/spinner_white_48"    android:pivotX="50%"    android:pivotY="50%"    android:framesCount="12"    android:frameDuration="100" />
