How to change color in circular progress bar?

For API 21 and Higher. Simply set the indeterminateTint property. Like:

android:indeterminateTint="@android:color/holo_orange_dark"

To support pre-API 21 devices:

mProgressSpin.getIndeterminateDrawable()
                .setColorFilter(ContextCompat.getColor(this, R.color.colorPrimary), PorterDuff.Mode.SRC_IN );

1.First Create an xml file in drawable folder under resource

named "progress.xml"

<?xml version="1.0" encoding="utf-8"?>
<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="3"
        android:shape="ring"
        android:thicknessRatio="8"
        android:useLevel="false" >

    <size
        android:height="76dip"
        android:width="76dip" />

    <gradient
        android:angle="0"
        android:endColor="color/pink"
        android:startColor="@android:color/transparent"
        android:type="sweep"
        android:useLevel="false" />

    </shape>

</rotate>

2.then make a progresss bar using the folloing snippet

<ProgressBar
    style="?android:attr/progressBarStyleLarge"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/relativeLayout1"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="20dp"
    android:indeterminate="true"
    android:indeterminateDrawable="@drawable/progress" />

In the res/drawable folder, put this:

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="#447a29" 
        android:endColor="#00ffffff"
        android:angle="0"/>

    </shape>

</rotate> 

Set startColor and endColor as per your choice .

Now set that progress.xml in ProgressBar's backgound .

Like this

<ProgressBar
  android:id="@+id/ProgressBar01" 
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:indeterminateDrawable="@drawable/progress"
 />
