Material-ViewPagerIndicator

A super easy-to-use page indicator for the Android Support Library v4's ViewPager widget with Material Design ink animations.

Demo

A demo app with examples is available on Google Play. The source for the demo is the app module in this project.

Usage

ViewPagerIndicator is a @ViewPager.DecorView (like Support-Design's TabLayout and Support-v4's PagerTabStrip and PagerTitleStrip) widgets.

Usage is simple - just add it as a child view of your ViewPager!

XML

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

    <!-- Add as a direct child of your ViewPager -->
    <com.itsronald.widget.ViewPagerIndicator
        android:id="@+id/view_pager_indicator"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|center_horizontal"
        android:gravity="center_vertical"/>

 </androidx.viewpager.widget.ViewPager>

Programatically

Or in code...

import androidx.viewpager.widget.ViewPager;
import android.view.Gravity;
import android.view.ViewGroup.LayoutParams;

import com.itsronald.widget.ViewPagerIndicator;

...

ViewPager viewPager = ...;

final ViewPager.LayoutParams layoutParams = new ViewPager.LayoutParams();
layoutParams.width = LayoutParams.MATCH_PARENT;
layoutParams.height = LayoutParams.WRAP_CONTENT;
layoutParams.gravity = Gravity.BOTTOM;

final ViewPagerIndicator viewPagerIndicator = new ViewPagerIndicator(context);
viewPager.addView(viewPagerIndicator, layoutParams);
