In the below example code I have created a Custom Circle Progress bar. Here first I have added Progress bar layout within activity_main.xml then I have created a new circular_progressbar.xml file in a drawable folder. In circular_progress bar.xml I have used rotate XML this rotate allows our form to rotate from 0 to 360 degrees. And I have also used shape.xml for creating a stylish progress bar, In shape.xml I have used these attributes- color, innerRadius, shape, useLevel and thickness.

For the ring you must set the following parameters:-

android:innerRadiusRatio – For using an inner radius of the ring

android:thicknessRatio – For using thickness of the ring

android:useLevel="true" – Indicates whether the progress bar level affects .

Step(1) activity_main.xml layout-

 <ProgressBar
        android:background="@color/center"
        android:indeterminate="true"
        android:layout_gravity="center"
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="120dp"
        android:layout_height="120dp"
        android:layout_centerInParent="true"
        android:indeterminateDrawable="@drawable/circular_progressbar" />

Step(2)-Created circular_progressbar.xml in drawable folder-
 

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="360">
    <shape
    android:innerRadiusRatio="4"
    android:shape="ring"
    android:useLevel="true"
    android:thickness="2dp">
    <solid android:color="@color/colorPrimaryDark"/>
    </shape>
</rotate>
