Attention

I'm not going to support this anymore. Just use a better solution, e.g. this one Indefinite-Pager-Indicator

BubblePagerIndicator

A view pager indicator view to deal with a large amount of pages. Nice scale and transition animations are supported.

Usage

  1. Add jcenter() to repositories block in your gradle file.
  2. Add implementation 'com.shuhart.bubblepagerindicator:bubblepagerindicator:1.1.2' to your dependencies.
  3. Add BubblePageIndicator into your layouts or view hierarchy:
<com.shuhart.bubblepagerindicator.BubblePageIndicator
    android:id="@+id/indicator"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/pager"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="32dp"
    android:layout_marginTop="32dp"
    app:bpi_fillColor="@color/colorAccent"
    app:bpi_pageColor="@color/colorPrimary"
    app:bpi_radius="8dp"
    app:bpi_marginBetweenCircles="6dp"
    app:bpi_onSurfaceCount="@integer/default_bubble_indicator_on_surface_count"
    app:bpi_risingCount="@integer/default_bubble_indicator_rising_count"/>

  1. Attach indicator to the ViewPager instance:
pager = findViewById(R.id.pager);
indicator = findViewById(R.id.indicator);
adapter = new ViewPagerAdapter();
pager.setAdapter(adapter);
indicator.setViewPager(pager);

An adapter should be attached to the ViewPager before calling indicator.setViewPager(pager).

  1. You can customize the behavior in runtime: java indicator.setOnSurfaceCount(3); indicator.setRisingCount(2); // resolved color indicator.setFillColor(ContextCompat.getColor(this, R.color.colorAccent)); // resolved color indicator.setPageColor(ContextCompat.getColor(this, R.color.colorPrimary)); // in px indicator.setRadius(getResources().getDimensionPixelSize(R.dimen.default_bubble_indicator_radius)); // in px indicator.setMarginBetweenCircles(getResources().getDimensionPixelSize( R.dimen.default_bubble_indicator_circles_margin));

Customization

Attribute Description Default Value
bpi_pageColor Current page circle color. #FFFFFF
bpi_fillColor Circles color #000000
bpi_radius Normal circle radius. 3dp
bpi_marginBetweenCircles Margin between centers of circles. 3dp
bpi_onSurfaceCount A number of circles with full radius (bpi_radius) 5
bpi_risingCount A number of scaled circles. 2

Maximum number of circles visible to the user is bpi_onSurfaceCount + bpi_risingCount * 2 (Default is 9).
At the beginning only bpi_onSurfaceCount + bpi_risingCount (Default is 7) circles are visible.
Radius for a rising circle is scaled by power of 2 with some correction applied.
In every aspect the library is mimicking the Instagram indicator behavior.
