To make the layout interactive and to look good, we need to modify the default of certain widgets. Here is the simple customisation of the progress bar:-

Step 1:- Create a drawable xml say customised_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="360">
           <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="@color/white"
                  android:endColor="@color/white"
                  android:angle="0"/>
            </shape>
        </rotate>

Step 2:- Add the above customised drawable in your progress bar.

<ProgressBar
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:background="@drawable/customised_progress" />
