Quick start

Just add this dependency into your build.gradle

Call this

pagerBullet.invalidateBullets();

when

pagerAdapter.notifyDataSetChanged();

Profit!

Customization

Text indicator

This library can show dots or text indicator, when ViewPager contains a lot of pages. You can set limit of pages, when you want to show text indicator (default value is 20).

Just add

pagerBullet.setTextSeparatorOffset(5);

and you will see text instead of dots, when pages more than 5:

You can customize this text by override

 <string name="pager_bullet_separator" formatted="false">%s / %s</string>

or color

 <color name="pager_bullet_text_indicator">#ffffff</color>

Dot color:

 <color name="pager_bullet_active">#836556</color>
  <color name="pager_bullet_inactive">#219382</color>

pagerBullet.setIndicatorTintColorScheme(Color.WHITE, Color.BLUE);

Dot size:

 <dimen name="pager_bullet_indicator_active_dot_diameter">12dp</dimen>
  <dimen name="pager_bullet_indicator_inactive_dot_diameter">8dp</dimen>

Dot margin:

 <dimen name="pager_bullet_indicator_dot_margin">4dp</dimen>

Dot container height:

<dimen name="pager_bullet_indicator_height">52dp</dimen>

app:panelHeightInDp="52dp"

like this:

<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
