如何在标签页(如Google Play)中启用水平滚动? [英] How to enable horizontal scroll in tab like Google Play?

问题描述

我指的是关于材料设计的很棒的示例.它具有选项卡，但是当我添加太多选项卡时，这些选项卡将被压缩(请参见屏幕截图).如何使其水平滚动?

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?

我相信下面是我应该进行更改的布局，但是我整理了文档，似乎无法得到它，请帮助！

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>

推荐答案

TabLayout具有方法

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

您还可以使用app:tabMode="scrollable"用XML定义它.

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