ScrollView 中的 ViewPager [英] ViewPager in ScrollView

问题描述

我需要在 ScrollView 中有一个 ViewPager 但 ViewPager 在 ScrollView 中时不会出现，当我不使用 ScrollView 时一切正常.

I need to have a ViewPager inside a ScrollView but ViewPager just does not appear when it's in ScrollView, everything is ok when i don't use ScrollView.

我在 stackoverflow 或其他网站上看到了一些这样的问题，并且所有这些问题都已得到回答，您必须将 android:fillViewport="true" 放入您的滚动视图解决这个问题，但是这个解决方案对我不起作用，即使我的 ScrollView<中有 android:fillViewport="true" 仍然没有出现 ViewPager/代码>.

I've seen a couple questions like this being asked here on stackoverflow or on other sites and all of them have been answered that you have to put android:fillViewport="true" to your scrollview to fix the problem, but this solution doesnt work for me, ViewPager still does not appear even if i have android:fillViewport="true" in my ScrollView.

我猜想在 android api 中发生了一些变化，这个解决方案不再起作用了，有谁知道我怎么可能让 ViewPager 出现在 ScrollView?

I guess something got changed in the android api's or something and this solution doesn't work anymore, does anyone know how i could possibly make a ViewPager appear in a ScrollView?

更新:一个工作的 ScrollView 布局 XML:

UPDATE: A working ScrollView layout XML:

<ScrollView
    android:id="@+id/scrollView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fillViewport="true">


    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical">

            <android.support.v4.view.ViewPager
                android:id="@+id/itemsViewPager2"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" >
            </android.support.v4.view.ViewPager>
    </LinearLayout>
 </ScrollView>

推荐答案

我过去也遇到过类似的问题.View-Pager 必须有一个设定的高度(它不能包装内容).由于 ViewPager 加载单独的页面，而不是一次加载，它不会知道包装内容"的实际含义.将 layout_height 设置为 fill_parent 或设置 dp 允许 ViewPager 静态设置它的高度并在其他布局中做出相应的反应.

I ran into a similar problem in the past. A View-Pager must have a set height (it cannot wrap-content). Since a ViewPager loads separate pages, and not all at once, it won't know what 'wrap-content' actually means. Setting the layout_height to fill_parent or a set dp allows the ViewPager to statically set it's height and react more accordingly within other layouts.
