How to solve:

Solution:

  1. Add a custom style in res/layout/values/styles.xml

You can find some examples here.

<style name="StyledIndicators" parent="@android:style/Theme.Light">
    <item name="vpiCirclePageIndicatorStyle">@style/CustomCirclePageIndicator</item>
</style>

<style name="CustomCirclePageIndicator">
    <item name="fillColor">#000000</item>
    <item name="strokeColor">#000000</item>
    <item name="strokeWidth">1dp</item>
    <item name="radius">6dp</item>
    <item name="centered">true</item>
</style>
  1. Add new style as a theme in your activity, “StyledIndicators”:

    <activity
        android:name=".YourActivity"
        android:theme="@style/StyledIndicators" >
    </activity>
    
  2. After that just need to change to theme to the one that comes with the project, choose Manifest Themes – StyledIndicators.

enter image description here

styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="android:Theme.Light.NoTitleBar">
    <item name="vpiCirclePageIndicatorStyle">@style/CustomCirclePageIndicator</item>
</style>
<style name="CustomCirclePageIndicator">
    <item name="fillColor">#FF888888</item>
    <item name="strokeColor">#FF000000</item>
    <item name="strokeWidth">2dp</item>
    <item name="radius">10dp</item>
    <item name="centered">true</item>
</style>
</resources>

Now in your Manifest File.
Add theme attribute under

<application
    android:icon="@drawable/icon"
    android:label="ViewPagerIndicator Sample"
    android:theme="@style/AppTheme" >

Dont forget to add

  android:theme="@style/AppTheme"

###

The activity using ViewPagerIndicator needs to have the appropriate styles in its theme.

In this sample project, I demonstrate setting up a custom theme with the requisite vpiTabPageIndicatorStyle:

<?xml version="1.0" encoding="utf-8"?>
<resources>

        <style name="AppTheme" parent="@style/Theme.Sherlock.Light">
                <item name="vpiTabPageIndicatorStyle">@style/TabStyle</item>
        </style>

        <style name="TabStyle" parent="Widget.TabPageIndicator">
                <item name="android:textColor">#FF33AA33</item>
                <item name="android:textSize">14sp</item>
                <item name="android:textStyle">italic</item>
                <item name="android:paddingLeft">16dp</item>
                <item name="android:paddingRight">16dp</item>
                <item name="android:fadingEdge">horizontal</item>
                <item name="android:fadingEdgeLength">8dp</item>
        </style>

</resources>

The same basic approach should work for vpiCirclePageIndicatorStyle, and I would imagine that the sample code that accompanies ViewPagerIndicator has an example of this.

###

To apply the custom style to the circle page indicator add the style attribute directly in your xml layout.

 <com.viewpagerindicator.CirclePageIndicator
        android:id="@+id/indicator"
        style="@style/CustomCirclePageIndicator"
        android:layout_height="wrap_content"
        android:padding="5dp"
        android:layout_width="fill_parent"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="20dp"/>
