Android 1.6的TabHost一个片段内 [英] Android 1.6 TabHost inside a Fragment

问题描述

在演示 Support4Demos - API 4+支持演示中，标签和TabsPager例子都扩展FragmentActivity。每个选项卡的内容本身就是一个片段。没有真正的突破，TabActivity使用了同样的方式，而不采用片段。

In the demo Support4Demos - API 4+ Support Demos , the Tabs and TabsPager examples both extend FragmentActivity. Each tab content is itself a Fragment. No real breakthrough, TabActivity was used the same way without the introduction of Fragment.

现在假设我的活动里面，屏幕部分是名为WidgetFragment片段。这怎么可能WidgetFragment含有一个TabHost？可视化包含在活动内的迷你TabHost。 我试图插入内片段的TabHost不是FragmentActivity无微不至。

Now suppose inside my Activity , a screen portion is a Fragment named WidgetFragment. How is it possible for WidgetFragment to contain a TabHost ? Visualize a mini TabHost contained inside an Activity. I tried every possible way to insert a TabHost inside a Fragment not a FragmentActivity.

推荐答案

在普遍接受的做法，标签适应整个屏幕。 大多数人（包括我）不知道该标签可以放在任何地方像一个简单的观点，ListView控件。 关键是要包括你的TabHost在另一个布局。当您创建TabHost，始终保持这些ID： tabhost，标签，tabcontent

In generally accepted practices, Tabs fit the whole screen. Most people (including me) are unaware the tabs can be placed anywhere like a simple view, ListView. The trick is to include your TabHost inside another layout. When you create the TabHost, always keep these id : tabhost , tabs , tabcontent

在主布局，包括您的tabhost.xml。在这里，我中心TabHost中间

In your main layout, include your tabhost.xml . Here I center the TabHost in the middle

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">
    <!-- Fill whatever you need -->     
    <FrameLayout
        android:id="@+id/widget_fragment"
        android:layout_centerVertical="true" android:layout_centerHorizontal="true"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content">
        <include layout="@layout/tabhost" />
    </FrameLayout> 
</LinearLayout>

在Support4Demos的标签和TabsPager例子看看好了，TabHost仍由FragmentActivity管理。每个选项卡的内容是一个片段。与TabActivity，它可能无法在任何地方有一个标签

Look well at the Tabs and TabsPager examples in Support4Demos , the TabHost is still managed by FragmentActivity. Each tab content is a fragment. With TabActivity, it may not be possible to have a tab anywhere
