是否可以将 ConstraintLayout 放在 ScrollView 中? [英] Is it possible to put a ConstraintLayout inside a ScrollView?

问题描述

最近，在 Android Studio 2.2 中，有一个新的 ConstraintLayout 使设计更容易，但与 RelativeLayout 和 Linearlayout 不同，我不能使用 ScrollView 包围 ConstraintLayout.这可能吗?如果是，怎么办?

So recently, with Android Studio 2.2 there's a new ConstraintLayout that makes designing a lot easier, but unlike RelativeLayout and Linearlayout, I can't use a ScrollView to surround ConstraintLayout. Is this possible? If so, how?

即

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:layout_editor_absoluteX="0dp"
        tools:layout_editor_absoluteY="0dp">
        
        <android.support.constraint.ConstraintLayout
            android:id="@+id/constraintLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            tools:layout_editor_absoluteX="0dp"
            tools:layout_editor_absoluteY="0dp">
            
            <!-- Have whatever children you want inside -->
            
        </android.support.constraint.ConstraintLayout>
        
</ScrollView>

目前更常用的是将 ScrollView 的 ConstraintLayout 高度设置为 wrap_content，效果很好，别忘了 fillViewPort，而且 Scroll 和 Nested 都只支持一个直接子级.

Currently, it is more usual to use the ScrollView with the ConstraintLayout height set to wrap_content, it works very well, don't forget the fillViewPort and that both Scroll and Nested support only one direct child.
