Android ViewPager with bottom dots

Quick start

1) Just add this dependency into your build.gradle

 repositories {
     mavenCentral()
     maven { url "https://jitpack.io" }
 }

and:

 implementation 'com.github.robohorse:PagerBullet:Tag'

2) Replace your default ViewPager by com.robohorse.pagerbullet.PagerBullet

3) Call this

pagerBullet.invalidateBullets();

when

pagerAdapter.notifyDataSetChanged();

4) 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>

or

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>

or

   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"
    android:layout_height="match_parent">

    <com.robohorse.pagerbullet.PagerBullet
        android:id="@+id/pagerBullet"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:panelHeightInDp="52dp" />

</FrameLayout>
