A lightweight, plug-and-play indefinite pager indicator for RecyclerViews & ViewPagers.
From now on, all the new updates will be published in jitpack.io.
To use the IndefinitePagerIndicator, simply add the gradle dependency to your module's build.gradle
file:
implementation 'com.github.rbro112:Android-Indefinite-Pager-Indicator:Tag'
or
implementation 'com.github.wching:Android-Indefinite-Pager-Indicator:Tag'
both of them work 😃
Min SDK supported is version 16 - Jelly Bean.
Attaching the indicator to a RecyclerView / Viewpager / Viewpager2 takes only one line of code. After this, the Indefinite Pager Indicator will handle everything else.
- Add the IndefinitePagerIndicator view to your XML file
<com.rbrooks.indefinitepagerindicator.IndefinitePagerIndicator
android:id="@+id/recyclerview_pager_indicator"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
...
/>
- Find the view in your activity, fragment, etc.
findViewById(R.id.recyclerview_pager_indicator);
- Attach the RecyclerView to your IndefinitePagerIndicator
indefinitePagerIndicator.attachToRecyclerView(recyclerView);
That's it! The IndefinitePagerIndicator will handle updating as your RecyclerView does.
- 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"
...
/>
- Find the view in your activity, fragment, etc.
findViewById(R.id.viewpager_pager_indicator);
- 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.
A sample application is included in the repository. To view the sample:
- Clone the repository locally
git clone git@github.com:rbro112/Android-Indefinite-Pager-Indicator.git
- Build and run the sample module.
To customize the IndefinitePagerIndicator, modify any of the following attributes in the XML code (or set them programmatically) for your IndefinitePagerIndicator view.
If you would like to help, submit a PR! We have the following features pending:
-
"Instagram" style -- Selected dot starts at the left of the view rather than starting in the center.
-
Support for padding.
-
Support for small drawables.
