Pager (especially for ViewPager) indicator in two styles: circle & fraction.

Demo

circle fraction

Dependency

implementation 'me.liangfei:pagerindicator:0.0.2'

Usage

Two attributes are provided:

  • app:indicator_type = [fraction | circle].
  • app:indicator_spacing works only for the circle type indicator.

Step 1: add PageIndicator to the bottom of the ViewPager.

<merge xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <androidx.viewpager.widget.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <me.liangfei.indicator.PagerIndicator
        android:id="@+id/indicator"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="20dp"
        android:layout_marginLeft="20dp"
        android:layout_marginStart="20dp"
        android:gravity="bottom|center_horizontal"
        app:indicator_spacing="5dp"
        app:indicator_type="fraction" />
</merge>

Step 2: pass the ViewPager instance to the PagerIndicator instance.

val pageIndicator = findViewById(R.id.indicator);
pageIndicator.setViewPager(pager);

You can just take PageIndicator as a normal view to make your layout, because it extends LinearLayout.

Check the app module for more details.
