To use the IndefinitePagerIndicator, simply add the gradle dependency to your module17;s build.gradle file:

compile 'com.ryanjeffreybrooks:indefinitepagerindicator:1.0.2'

Getting Started

Attaching the indicator to a RecyclerView or Viewpager takes only one line of code. After this, the Indefinite Pager Indicator will handle everything else.

RecyclerView

  1. Add the IndefinitePagerIndicator to your XML file
<com.rbrooks.indefinitepagerindicator.IndefinitePagerIndicator
        :id="@+id/recyclerview_pager_indicator"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ... 
        />
  1. Find the view in your activity, fragment, etc.
findViewById(R.id.recyclerview_pager_indicator);
  1. Attach the RecyclerView to your IndefinitePagerIndicator
indefinitePagerIndicator.attachToRecyclerView(recyclerView);

That’s it! The IndefinitePagerIndicator will handle updating as your RecyclerView does.

ViewPager

  1. Add the IndefinitePagerIndicator view to your XML file
<com.rbrooks.indefinitepagerindicator.IndefinitePagerIndicator
        android:id="@+id/viewpager_pager_indicator"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ... 
        />
  1. Find the view in your activity, fragment, etc.
findViewById(R.id.viewpager_pager_indicator);
  1. Attach the ViewPager to your IndefinitePagerIndicator
indefinitePagerIndicator.attachToViewPager(viewPager);

That’s it! The IndefinitePagerIndicator will handle updating as your ViewPager does.

The position of the ViewPager can also be changed programmatically with viewPager.setCurrentItem(position) and the IndefinitePagerIndicator will update successfully.

TODO:

Actively working on these. If you would like to help, submit a PR!

“Instagram” style — Selected dot starts at the left of the view rather than starting in the center.
