Android HorizontalPaging Sample

This sample shows how to implement tabs, using Fragments and a ViewPager.

Introduction

This sample implements tabs using the deprecated ActionBar.TabListener. It uses ViewPager and FragmentPagerAdapter to handle swiping between tabs and displaying the selected tab content.

  1. Create an Activity that extends FragmentActivity, with a ViewPager for its layout.
  2. Implement ActionBar.TabListener interface.
  3. Create a class that extends FragmentPagerAdapter and override its getItem(int position), getCount() and getPageTitle(int position) methods.
  4. In the onCreate(Bundle savedInstanceState) method of your activity, set navigation mode to tabs for the ActionBar using setNavigationMode(ActionBar.NAVIGATION_MODE_TABS). Note: This is DEPRECATED as of Android Lollipop.
  5. Set your custom FragmentPagerAdapter on your ViewPager.
  6. Implement setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener()) on your ViewPager to know the selected tab, so you can update your ActionBar with setSelectedNavigationItem(position).

Pre-requisites

  • Android SDK 27
  • Android Build Tools v27.0.2
