I'm updating this CL as I go to fix all the issue we can find. * Icon lists items now use correct icons, and are rearranged to be consistent. * Removed HTML comments that were interfering with the Liquid templates. * Added the benefits list to the docsite-index. * Capitalized "Design" in Material Design. * Spec links in icon list now use consistent labels. * URLs, headings and page titles are now internally consistent within the platform.

# TabLayout
|
|
|
|
`TabLayout` provides a horizontal layout to display tabs. The layout handles
|
|
interactions for a group of tabs including:
|
|
|
|
- scrolling behavior,
|
|
- (swipe) gestures,
|
|
- tab selection,
|
|
- animations,
|
|
- and alignment.
|
|
|
|
The Android Developers site provides [detailed documentation](https://developer.android.com/reference/android/support/design/widget/TabLayout.html)
|
|
on implementing TabLayout.

## Usage
|
|
|
|
The Material Design guidelines for individual tabs is done in the tabs
|
|
themselves; the TabLayout displays groups of these tabs and controls how they
|
|
interact with each other.
|
|
|
|
A TabLayout is a single row of tabs and can be fixed or scrollable. For a fixed
|
|
layout, the maximum number of tabs is limited by the size and number of the tabs
|
|
and the screen size. Fixed tabs have equal width, based on the widest tab text.
|
|
|
|
A tab layout should be used above the content associated with the respective
|
|
tabs and lets the user quickly change between content views. These content views
|
|
are often held in a
|
|
[ViewPager](https://developer.android.com/reference/android/support/v4/view/ViewPager.html).
|
|
|
|
Use [setupWithViewPager(ViewPager)](https://developer.android.com/reference/android/support/design/widget/TabLayout.html#setupWithViewPager(android.support.v4.view.ViewPager))
|
|
to link a TabLayout with a ViewPager. The
|
|
individual tabs in the TabLayout will be automatically populated with the page
|
|
titles from the PagerAdapter.
|
|
|
|
Alternatively, you can add a TabLayout to a ViewPager in XML:
|
|
|
|
```xml
|
|
<android.support.v4.view.ViewPager
|
|
android:layout_width="match_parent"
|
|
android:layout_height="match_parent">
|
|
|
|
<android.support.design.widget.TabLayout
|
|
android:layout_width="match_parent"
|
|
android:layout_height="wrap_content"
|
|
android:layout_gravity="top" />
|
|
|
|
</android.support.v4.view.ViewPager>
|
|
```
