滚动未启用

Question

我设计了一个注册屏幕，其中有一个 Scroll view ，但 Scroll view 不起作用。

我无法找到 Scroll 无法正常工作的原因，请帮帮我。

以下是代码供参考：

Answer 1

试试这样，在Linear layout里面添加，它会一直滚动到页尾。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

     <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

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

// Your xml Code Put Here

        </LinearLayout>
    </ScrollView>
</Relativelayout>

Answer 2

解决办法可以把ScrollView改成：

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fillViewport="true"
    >

那么你也应该改变嵌套的布局高度
