How to set thickness of circular indeterminate progress bar android?

问题

I have two nested circular indeterminate progress bars but I cannot set their thickness to an equal size. I have tried to customize it using shapes. However, that removes the default behaviour of the circular indeterminate progress. I customize like this and it made thickness equal but not getting default behaviour.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/progress">
        <rotate android:toDegrees="360">
            <shape
                android:shape="ring"
                android:thickness="4dp">
                <solid android:color="@color/white" />
            </shape>
        </rotate>
    </item>
</layer-list>

<ProgressBar
      android:id="@+id/download_progress4"
      android:layout_width="85dp"
      android:layout_height="85dp"
      android:layout_gravity="center"
      android:indeterminate="true"
      android:indeterminateDrawable="@style/ProgressThem" />

I want like this with default behaviour of circular indeterminate progress bar

android:innerRadiusRatio="3"
android:thicknessRatio="20.0

                android:thickness="4dp"
                android:innerRadiusRatio="3"
                android:thicknessRatio="20.0">
