Using tabs 
Before you can use Material tabs, you need to add a dependency to the Material Components for Android library. For more information, go to the Getting started page.
Basic usage 

A TabLayout can be added to a layout:
xml
<com.google.android.material.tabs.TabLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    ...
</com.google.android.material.tabs.TabLayout>TabItems can then be added as children of the TabLayout and adjusted as needed:
xml
<com.google.android.material.tabs.TabLayout
    ...>
    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/text_label_1"
        />
    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/text_label_2"
        />
    ...
</com.google.android.material.tabs.TabLayout>Observe changes to tab selections:
kt
tabLayout.addOnTabSelectedListener(object : TabLayout.OnTabSelectedListener {
    override fun onTabSelected(tab: TabLayout.Tab?) {
        // Handle tab select
    }
    override fun onTabReselected(tab: TabLayout.Tab?) {
        // Handle tab reselect
    }
    override fun onTabUnselected(tab: TabLayout.Tab?) {
        // Handle tab unselect
    }
})API and source code:
TabLayoutTabItem
Making tabs accessible 
The Android tab components support screen reader descriptions for tabs and badges. While optional, we strongly encourage their use.
Content descriptions 
Adding a content description to the entire TabLayout can be done in XML with the android:contentDescription attribute or programmatically:
kt
tabLayout.contentDescription = contentDescriptionContent descriptions can also be added to individual tabs:
kt
val tab = tabLayout.getTabAt(index)
tab?.contentDescription = contentDescriptionBadgeDrawable also has a number of content description setters for different badge states:
kt
val badge = tab.getOrCreateBadge()
// For badges with a number
badge.setContentDescriptionNumberless(contentDescription)
badge.setContentDescriptionQuantityStringsResource(R.string.content_description)
badge.setContentDescriptionExceedsMaxBadgeNumberStringResource(R.string.content_description)
// For badges with a text
badge.setContentDescriptionForText(contentDescription)Using tabs with ViewPager 
A TabLayout can be set up with a ViewPager in order to:
- Dynamically create 
TabItems based on the number of pages, their titles, etc. - Synchronize the selected tab and tab indicator position with page swipes
 
First, your PagerAdapter (or subclass) needs to override the getPageTitle function in order to set the tab text label:
kt
class Adapter : PagerAdapter() {
    ...
    override fun getPageTitle(position: Int): CharSequence? {
        // Return tab text label for position
    }
}After the adapter has been set on the ViewPager, synchronize the TabLayout:
kt
tabLayout.setupWithViewPager(viewPager)Further customization of the dynamically-created TabItems (such as setting icons) needs to be done separately:
kt
val tab = tabLayout.getTabAt(index)
tab?.icon = drawableUsing tabs with ViewPager2 
Setting up a TabLayout with a ViewPager2 relies on the same concepts as doing so with a ViewPager, but the implementation is different. Everything is handled by the TabLayoutMediator class:
kt
TabLayoutMediator(tabLayout, viewPager2) { tab, position ->
    when (position) {
        0 -> {
            tab.text = textLabel1
            tab.icon = drawable1
        }
        1 -> {
            tab.text = textLabel2
            tab.icon = drawable2
        }
        ...
    }
}.attach()Adding badges to tabs 

Tabs support badging with the BadgeDrawable class:
kt
// Get badge from tab (or create one if none exists)
val badge = tab.getOrCreateBadge()
// Customize badge
badge.number = number
// Remove badge from tab
tab.removeBadge()Types 
There are two types of tabs: 1. Fixed tabs, 2. Scrollable tabs

Fixed tabs 
Fixed tabs display all tabs on one screen, with each tab at a fixed width. The width of each tab is determined by dividing the number of tabs by the screen width. They don’t scroll to reveal more tabs; the visible tab set represents the only tabs available.
Fixed tabs example 
The following example shows a row of fixed tabs.

In the layout:
xml
<com.google.android.material.tabs.TabLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabMode="fixed">
    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/tab_1"
        android:icon="@drawable/ic_favorite_24dp"
        />
    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/tab_2"
        android:icon="@drawable/ic_music_24dp"
        />
    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/tab_3"
        android:icon="@drawable/ic_search_24dp"
        />
</com.google.android.material.tabs.TabLayout>Scrollable tabs 
Scrollable tabs are displayed without fixed widths. They are scrollable, such that some tabs will remain off-screen until scrolled.
Scrollable tabs example 
The following example shows a row of scrollable tabs.

In the layout:
xml
<com.google.android.material.tabs.TabLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabMode="scrollable"
    app:tabContentStart="56dp">
    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/tab_1"
        />
    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/tab_2"
        />
    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/tab_3"
        />
    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/tab_4"
        />
    <com.google.android.material.tabs.TabItem
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/tab_5"
        />
    ...
</com.google.android.material.tabs.TabLayout>Anatomy and key properties

- Container
 - Active icon (optional if there’s a label)
 - Active text label (optional if there’s an icon)
 - Active tab indicator
 - Inactive icon (optional if there’s a label)
 - Inactive text label (optional if there’s an icon)
 - Tab item

Theming tabs 
Tabs support Material Theming which can customize color and typography.
Tabs theming example 
API and source code:
TabLayoutTabItem
The following example shows a row of scrollable tabs with Material Theming.

Implementing tabs theming 
Use theme attributes and styles in res/values/styles.xml which applies to all tabs and affects other components:
xml
<style name="Theme.App" parent="Theme.Material3.*">
    ...
    <item name="colorPrimary">@color/shrine_pink_900</item>
    <item name="colorSurface">@color/shrine_pink_light</item>
    <item name="colorOnSurface">@color/shrine_pink_900</item>
    <item name="textAppearanceLabelLarge">@style/TextAppearance.App.LabelLarge</item>
</style>
<style name="TextAppearance.App.LabelLarge" parent="TextAppearance.Material3.LabelLarge">
    <item name="fontFamily">@font/rubik</item>
    <item name="android:fontFamily">@font/rubik</item>
</style>Use default style theme attributes, styles and theme overlays, which apply to all tabs but do not affect other components:
xml
<style name="Theme.App" parent="Theme.Material3.*">
    ...
    <item name="tabStyle">@style/Widget.App.LabelLarge</item>
</style>
<style name="Widget.App.TabLayout" parent="Widget.Material3.TabLayout">
    <item name="materialThemeOverlay">@style/ThemeOverlay.App.TabLayout</item>
    <item name="tabTextAppearance">@style/TextAppearance.App.LabelLarge</item>
</style>
<style name="ThemeOverlay.App.TabLayout" parent="">
    <item name="colorPrimary">@color/shrine_pink_900</item>
    <item name="colorSurface">@color/shrine_pink_light</item>
    <item name="colorOnSurface">@color/shrine_pink_900</item>
</style>Use the style in the layout, which affects only these tabs:
xml
<com.google.android.material.tabs.TabLayout
    ...
    style="@style/Widget.App.TabLayout"
    />
