使用 CoordinatorLayout 时，我的 ScrollView 大小不正确 [英] When using the CoordinatorLayout my ScrollView has an incorrect size

问题描述

我在布局中使用 ScrollView，并尝试使用新的 CoordinatorLayout 来自设计支持库.

I'm using a ScrollView in a layout, and am attempting to use the new CoordinatorLayout from the design support library.

我的布局文件如下所示:

My layout file looks like this:

<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

  <ScrollView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      app:layout_behavior="@string/appbar_scrolling_view_behavior">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
      ...
    </LinearLayout>
  </ScrollView>
  <android.support.design.widget.AppBarLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content">
    <android.support.v7.widget.Toolbar ... />
  </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

测试时，滚动视图仅占据屏幕的一部分.出了什么问题?

When testing this the scrollview only occupies part of the screen. What went wrong?

推荐答案

标准的 ScrollView 只能用作父级.您需要将 ScrollView 更改为 android.support.v4.widget.NestedScrollView.

The standard ScrollView is only meant to be used as a parent. You need to change the ScrollView to a android.support.v4.widget.NestedScrollView.

一个例子可以在AppBarLayout.

An example can be seen in the reference documentation for AppBarLayout.
