How to enable horizontal scroll in tab like Google Play?

问题

I'm referencing a great demo here regarding material design. It has tabs, but when I add too many the tab items get squished (see screenshot). How can I make it scroll horizontally?

I believe below is the layout I should make the change, but I combed the docs and can't seem to get it, pls help!

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_scrollFlags="scroll|enterAlways" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

    </android.support.design.widget.AppBarLayout>

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"
        android:layout_margin="@dimen/fab_margin"
        android:src="@drawable/ic_done" />

</android.support.design.widget.CoordinatorLayout>

回答1:

TabLayout has a method setTabMode() which can be either MODE_FIXED (default) or MODE_SCROLLABLE which is what you need.

You can also define this in XML with app:tabMode="scrollable".

回答2:

You can add this app:tabMode="scrollable" to your android.support.design.widget.TabLayout

回答3:

SlidingTabLayout and SlidingTabStrip classes is what are you looking for You need to copy these classes from google developers site, add sliding tab layout in xml, and in set viewpager for sliding tab layout in java. Hope it'll help.
