带水平滚动的 FragmentTabHost [英] FragmentTabHost with horizontal scroll

问题描述

我正在尝试构建 FragmentTabHost 并使其水平滚动.我一直在寻找解决方案但找不到任何东西，所有帖子都是关于普通 TabHost 的.

I am trying to build a FragmentTabHost and make it horizontal Scrollable. I've been searching for a solution but couldn't find anything, all posts are about normal TabHost.

我正在使用 FragmentTabHost

我的布局是:

<android.support.v4.app.FragmentTabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:tag="trip_entry_tab"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />
    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_weight="0"/>
    <FrameLayout
        android:id="@+id/realtabcontent"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"/>
</LinearLayout>

已经尝试将 tabwidget 嵌套到水平滚动视图中(这是我在其他帖子中可以找到的解决方案，但始终用于 TabHost 而不是用于 FragmentTabHost)，但没有任何变化:

Already tried to nest the tabwidget into an horizontal scroll view (this is the solution I could find in other posts, but always for TabHost and not for FragmentTabHost), but nothing changes:

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

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

我的标签刚刚缩小了，这真的不好看.有人让片段标签主机可滚动吗?

My tabs just got shrinked and that is really not nice looking. Has somebody make it to get a fragment tab host scrollable?

谢谢

推荐答案

根据我的经验，FragmentTabHost 不太关心 xml 定义，事情必须以编程方式进行.我通过从 xml 中删除 Horizo​​ntalScrollView 并将其添加到我的 onCreate 中为 FragmentActivity 使其工作.

Based on my experience, the FragmentTabHost doesn't care much about the xml definitions, things must be made programmatically. I got it working by leaving out the HorizontalScrollView from the xml and adding it in my onCreate for the FragmentActivity.

xml:

<android.support.v4.app.FragmentTabHost xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@android:id/tabhost"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

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

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal" />

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_weight="0" />

        <FrameLayout
            android:id="@+id/realtabcontent"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1" />
    </LinearLayout>

</android.support.v4.app.FragmentTabHost>

然后在添加选项卡后的 onCreate 中(也以编程方式):

Then in the onCreate after adding the tabs (also programmatically):

TabWidget tw = (TabWidget) findViewById(android.R.id.tabs);
LinearLayout ll = (LinearLayout) tw.getParent();
HorizontalScrollView hs = new HorizontalScrollView(this);
hs.setLayoutParams(new FrameLayout.LayoutParams(
    FrameLayout.LayoutParams.MATCH_PARENT,
    FrameLayout.LayoutParams.WRAP_CONTENT));
ll.addView(hs, 0);
ll.removeView(tw);
hs.addView(tw);
hs.setHorizontalScrollBarEnabled(false);

不知道这是否是最优雅的解决方案，但它似乎工作正常.

Don't know if this is the most elegant solution but it seems to work OK.
