具有Horizo​​ntalScrollView的FragmentTabHost

Question

我正在尝试将Horizo​​ntalScrollView添加到FragmentTabHost。我遵循了FragmentTabHost with horizontal scroll的“ Lor Giver”答案 但它对我不起作用。 像这样实现xml之后：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

<android.support.v4.app.FragmentTabHost
    android:id="@+id/tabHost"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentTop="true">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <HorizontalScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:fillViewport="true"
            android:scrollbars="none">

            <TabWidget
                android:id="@+id/tabs"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="bottom"/>
        </HorizontalScrollView>


        <FrameLayout
            android:id="@+id/tabHostContent"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginTop="48dp" />
    </LinearLayout>
</android.support.v4.app.FragmentTabHost>

并像这样设置它：

override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    val view = inflater!!.inflate(R.layout.home_tabs, container, false)
    viewContext = view.context
    tabHost = view.findViewById(R.id.tabHost)
    tabHost.setup(view.context, fragmentManager, R.id.tabHostContent)
    tabHost.addTab(tabHost.newTabSpec("home").setIndicator(context!!.getString(R.string.TAB_EMERGENCY)), EmergencyFragment::class.java, null)
    tabHost.addTab(tabHost.newTabSpec("friends").setIndicator(context.getString(R.string.TAB_PRIVATE)), PrivateFragment::class.java, null)
    tabHost.addTab(tabHost.newTabSpec("organizations").setIndicator(context!!.getString(R.string.ORGANIZATIONS)), OrganizationsFragment::class.java, null)
    tabHost.tabWidget.dividerDrawable = null
    tabHost.tabWidget.isStripEnabled = false
    changeStyleOfSelectedTab()
    tabHost.setOnTabChangedListener {
        changeStyleOfSelectedTab()
        (activity as MainActivity).tabChangedByClick(currentTab)
    }
    return view
}

我的标签没有水平滚动。最后一个标题（“组织”）刚刚包装好自己（屏幕上不合适）。 添加

之后

tabHost.tabWidget.getChildAt(i).findViewById<TextView>(android.R.id.title).setSingleLine(true)

对于每个选项卡，组织TITLE开始在其选项卡内滚动。我在做什么错了？
