Android%20Arsenal-CircularBarPager-brightgreen.svg?style=flat)

A Lollipop material design styled CircularBarPager library (API 10+).

To include in your project, add this to your build.gradle file:

   //CircularBarPager
   compile 'com.github.orangegangsters:library:1.3.4@aar'
   //CirclePageIndicator
   compile 'com.viewpagerindicator:library:2.4.1@aar'
   //Animations and progress value easing
   compile 'com.daimajia.easing:library:2.1@aar'

Starting from version 1.3.10, we are moving to a new package name (we skipped from 1.3.4 to 1.3.10):

   //CircularBarPager
   compile 'com.github.omadahealth:library:1.3.11@aar'
   //CirclePageIndicator
   compile 'com.viewpagerindicator:library:2.4.1@aar'
   //Animations and progress value easing
   compile 'com.daimajia.easing:library:2.1@aar'

Usage

Look at the example app for a live example on how to use the library.

Preparing dependencies

In order to use the CirclePageIndicator by Square, you need to add a repo to your main build.gradle file:

allprojects {
    repositories {
        maven { url 'http://dl.bintray.com/populov/maven/' }
        jcenter()
    }
}

In XML:

<com.github.omadahealth.circularbarpager.library.CircularBarPager
        android:id="@+id/circularBarPager"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:paddingLeft="30dp"
        android:paddingRight="30dp"
        android:layout_centerInParent="true"
        style="@style/CircularBarPagerStyle"/>

In styles.xml

 <style name="CircularBarPagerStyle">
        <item name="android:layout_height">match_parent</item>
        <item name="android:layout_width">match_parent</item>

        <item name="progress_arc_max">100</item>
        <item name="arc_progress">0</item>



        <item name="progress_arc_clockwise_outline_width">0.75dp</item>
        <item name="progress_arc_counter_clockwise_outline_width">0.75dp</item>
        <item name="progress_arc_clockwise_width">8dp</item>
        <item name="progress_arc_counter_clockwise_width">8dp</item>
        
        <item name="progress_start_line_enabled">true</item>
        <item name="progress_pager_on_click_enabled">true</item>
        <item name="progress_pager_fill_circle_color">#00000000</item>
</style>

Customization

You can change several attributes in the XML file:

app:arc_progress [integer def:0 0-100] –> The default arc progress when start up
app:progress_arc_max [integer def:100 0-100] –> The maximum arc progress
app:progress_arc_clockwise_color [color hex] –> The main color in clockwise mode
app:progress_arc_clockwise_outline_color [color hex] –> The outline color in clockwise mode
app:progress_arc_counter_clockwise_color [color hex] –> The outline color in counter-clockwise mode
app:progress_arc_counter_clockwise_outline_color [color hex] –> The outline color in counter-clockwise mode
app:progress_arc_clockwise_width [integer dp] –> The width size of the main color in clockwise mode
app:progress_arc_clockwise_outline_width [integer dp] –> The width size of the outline color in clockwise mode
app:progress_arc_counter_clockwise_width [integer dp] –> The width size of the color in counter-clockwise mode
app:progress_arc_counter_clockwise_outline_width [integer dp] –> The width size of the outline color in counter-clockwise mode
app:progress_pager_on_click_enabled [boolean] –> The boolean that enables or disables the click enabled (on click, changes page)
app:progress_start_line_enabled [boolean] –> The boolean that enables the line that displays the starting position of the pager
app:progress_pager_on_click_enabled [boolean] –> The boolean that enables the user to change pages with a click as well as a slide
app:progress_pager_fill_circle_color [color hex] –> The color to fill the circle, transparent as default
app:progress_pager_fill_mode [enum int] –> The mode to fill the circle, “default_mode” or “pie_mode”

You can access every components programmatically by getting the CircularBarPager object:

CircularBarPager mCircularBarPager = (CircularBarPager) findViewById(R.id.circularBarPager);
CircularBar circularBar = mCircularBarPager.getCircularBar();
ViewPager viewPager = mCircularBarPager.getViewPager();
CirclePageIndicator circlePageIndicator = mCircularBarPager.getCirclePageIndicator();

Credits

We used ViewPagerIndicator from JakeWharton (https://github.com/JakeWharton/ViewPagerIndicator) for the page indicator at the bottom of the CircularBarPager
We used AnimationEasingFunctions from daimajia (https://github.com/daimajia/AnimationEasingFunctions) to also use beautiful animations on API 10+
