A simple customizable indicator for ViewPagers
Installation:
1) Add the following to the main project gradle file:
    allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }
2) Add this to the module gradle file:
    dependencies {
            compile 'com.github.ravindu1024:android-viewpager-indicator:1.0.1'
    }
Usage:
1) add using xml:
    <com.ravindu1024.indicatorlib.ViewPagerIndicator
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal|center_vertical"
        android:id="@+id/pager_indicator"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"/>
2) Then in code:
    ViewPagerIndicator indicator = (ViewPagerIndicator) findViewById(R.id.pager_indicator);
    indicator.setPager(pager);  //pager - the target ViewPager
NOTE: Changes to the ViewPager pages at runtime will be automatically handled when you call notifyDataSetChanged().
