This library has now been deprecated by the new Android Support Design Library. Please see the full component for a sample: https://components.xamarin.com/view/xamandroidsupportdesign

Interactive paging indicator widget, compatible with the ViewPager from the Android Support Library.

This library requires Support v7 AppCompat Version 23

Must set Compile with API 23 in VS or XS

You must add Mono.Android.Export.dll to your References

Build status:

Ported from: https://github.com/jpardogo/PagerSlidingTabStrip

For a working implementation of this project see the Sample/ folder.

1. Download the NuGet Package: https://www.nuget.org/packages/Refractored.PagerSlidingTabStrip/

Or add the library as a project.

2. Include the PagerSlidingTabStrip widget in your layout. This should usually be placed above the ViewPager it represents.

   <com.refractored.PagerSlidingTabStrip android:id="@+id/tabs" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" />

3. In your OnCreate method (or OnCreateView for a fragment), bind the widget to the ViewPager.

   // Initialize the ViewPager and set an adapter
   var pager =  FindViewById<ViewPager>(Resource.Id.pager);
   pager.Adapter = new TestAdapter(SupportFragmentManager);
   
   // Bind the tabs to the ViewPager
   var tabs = FindViewById<PagerSlidingTabStrip>(Resource.Id.tabs);
   tabs.SetViewPager(pager);
   

4. If your adapter implements the interface CustomTabProvider you can pass your custom tab view/s. In case the view returned contains the id Resource.Id.psts_tab_title, this view should be a TextView and will be used to place the title. If you don't want the library to manage your TextView title for the tab, use a different id than Resource.Id.psts_tab_title in your tab layout.

   If your adapter doesn't impelement the interface CustomTabProvider the default tab will be used (That's a TextView with id Resource.Id.psts_tab_title).

5. (Optional) If you use implement IOnPageChangeListener with your view pager you should set it in the widget rather than on the pager directly.

   // continued from above
   tabs.SetOnPageChangeListener(pageChangeListener);
   

From theme:

• android:textColorPrimary value (from your theme) will be applied automatically to tab's text color (Selected tab with 255 alpha and non selected tabs with 150 alpha), underlineColor, dividerColor, and indicatorColor, if the values are not defined on the xml layout.

Notes about some of the native attr:

• android:textSize Tab text size
• android:textColor Non selected tabs text color. If you DO define textColor It will be apply to NON selected tabs and NO ALPHA will be applied to them, the colour you define is the one you will see. If you want to define a half transparent color in textColor, you can pass #80FFFFFF (That's an example for half transparent white)
• android:paddingLeft or android:paddingRight layout padding. If you apply both, they should be balanded.

Custom attr:

• pstsIndicatorColor Color of the sliding indicator. textPrimaryColor will be it's default color value.
• pstsUnderlineColor Color of the full-width line on the bottom of the view. textPrimaryColor will be it's default color value.
• pstsUnderlineHeight Height of the full-width line on the bottom of the view.
• pstsTextAlpha Set the text alpha transparency for non selected tabs. Range 0..255. 150 is it's default value. It WON'T be use if textColor is defined in the layout. If textColor is NOT defined, It will be applied to the non selected tabs.
• pstsTextColorSelected Set selected tab text color. textPrimaryColor will be it's default color value.
• pstsTextStyle Set the text style, default bold.
• pstsTextSelectedStyle Set the text style of the selected tab, default bold.
• pstsTextAllCaps If true, all tab titles will be upper case, default true.
• pstsDividerColor Color of the dividers between tabs. textPrimaryColor will be it's default color value.
• pstsDividerPadding Top and bottom padding of the dividers.
• pstsDividerWidth Stroke width of divider line, defaults to 0.
• pstsIndicatorHeightHeight of the sliding indicator.
• pstsTabPaddingLeftRight Left and right padding of each tab.
• pstsScrollOffset Scroll offset of the selected tab.
• pstsTabBackground Background drawable of each tab, should be a StateListDrawable.
• pstsShouldExpand If set to true, each tab is given the same weight, default false.
• pstsPaddingMiddle If true, the tabs start at the middle of the view (Like Newsstand google app).

Almost all attributes have their respective getters and setters to change them at runtime , open an issue if you miss any.
