View Pager

Allows swiping between fragments.

 <?xml version="1.0" encoding="utf-8"?> 
    <LinearLayout xmlns:android=
     "http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 
    <android.support.v4.view.ViewPager  xmlns:android=
    "http://schemas.android.com/apk/res/android" 
        android:id="@+id/pager" 
        android:layout_width="match_parent" 
        android:layout_height="match_parent" /> 

    </LinearLayout>

class MainActivity : BaseActivity() { 
      override val tag = "Main activity" 
      override fun getLayout() = R.layout.activity_main 
      override fun getActivityTitle() = R.string.app_name 

      override fun onCreate(savedInstanceState: Bundle?) { 
        super.onCreate(savedInstanceState) 
        pager.adapter = ViewPagerAdapter(supportFragmentManager) 
    } 

    private class ViewPagerAdapter(manager: FragmentManager) :  
    FragmentStatePagerAdapter(manager) { 
      override fun getItem(position: Int): Fragment { 
        return ItemsFragment() 
      } 

      override fun getCount(): Int { 
        return 5 
    } 
  } 
}
