推荐答案

您需要一个子容器为的LinearLayout ， TableLayout 或 RelativeLayout的在滚动型是这样的：

You need a child container as LinearLayout, TableLayout or RelativeLayout in your ScrollView like this:

<ScrollView 
    ... >

    <LinearLayout
        ... >

        <!-- Your views: TextView, LinearLayout, etc. -->

    </LinearLayout>

</ScrollView>

根据参考：

一个滚动型是一个的FrameLayout，这意味着你应该把一个孩子在里面包含的全部内容以滚动

A ScrollView is a FrameLayout, meaning you should place one child in it containing the entire contents to scroll
