TabLayout

public class TabLayout
extends HorizontalScrollView

java.lang.Object
   ↳ android.view.View
     ↳ android.view.ViewGroup
       ↳ android.widget.FrameLayout
         ↳ android.widget.HorizontalScrollView
           ↳ com.google.android.material.tabs.TabLayout

TabLayout provides a horizontal layout to display tabs.

Population of the tabs to display is done through TabLayout.Tab instances. You create tabs via newTab(). From there you can change the tab's label or icon via setText(int) and setIcon(int) respectively. To display the tab, you need to add it to the layout via one of the addTab(Tab) methods. For example: 

 TabLayout tabLayout = ...;
 tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
 tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
 tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));
You should add a listener via addOnTabSelectedListener(OnTabSelectedListener) to be notified when any tab's selection state has been changed.

You can also add items to TabLayout in your layout through the use of TabItem. An example usage is like so: 

 <com.google.android.material.tabs.TabLayout
         android:layout_height="wrap_content"
         android:layout_width="match_parent">

     <com.google.android.material.tabs.TabItem
             android:text="@string/tab_text"/>

     <com.google.android.material.tabs.TabItem
             android:icon="@drawable/ic_android"/>

 </com.google.android.material.tabs.TabLayout>

ViewPager integration

If you're using a ViewPager together with this layout, you can call setupWithViewPager(ViewPager) to link the two together. This layout will be automatically populated from the PagerAdapter's page titles.

This view also supports being used as part of a ViewPager's decor, and can be added directly to the ViewPager in a layout resource file like so: 

 <androidx.viewpager.widget.ViewPager
     android:layout_width="match_parent"
     android:layout_height="match_parent">

     <com.google.android.material.tabs.TabLayout
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:layout_gravity="top" />

 </androidx.viewpager.widget.ViewPager>

void setTabMode (int mode)

Set the behavior mode for the Tabs in this layout. The valid input options are:

  • MODE_FIXED: Fixed tabs display all tabs concurrently and are best used with content that benefits from quick pivots between tabs.
  • MODE_SCROLLABLE: Scrollable tabs display a subset of tabs at any given moment, and can contain longer tab labels and a larger number of tabs. They are best used for browsing contexts in touch interfaces when users don’t need to directly compare the tab labels. This mode is commonly used with a ViewPager.

Parameters
mode int: one of MODE_FIXED or MODE_SCROLLABLE.

setupWithViewPager

void setupWithViewPager (ViewPager viewPager)

The one-stop shop for setting up this TabLayout with a ViewPager.

This is the same as calling setupWithViewPager(ViewPager, boolean) with auto-refresh enabled.

Parameters
viewPager ViewPager: the ViewPager to link to, or null to clear any previous link

setupWithViewPager

void setupWithViewPager (ViewPager viewPager, 
                boolean autoRefresh)

The one-stop shop for setting up this TabLayout with a ViewPager.

This method will link the given ViewPager and this TabLayout together so that changes in one are automatically reflected in the other. This includes scroll state changes and clicks. The tabs displayed in this layout will be populated from the ViewPager adapter's page titles.

If autoRefresh is true, any changes in the PagerAdapter will trigger this layout to re-populate itself from the adapter's titles.

If the given ViewPager is non-null, it needs to already have a PagerAdapter set.

Parameters
viewPager ViewPager: the ViewPager to link to, or null to clear any previous link
autoRefresh boolean: whether this layout should refresh its contents if the given ViewPager's content changes
