是否可以将ConstraintLayout放入ScrollView中？

Question

是否可以将ConstraintLayout放入ScrollView中？

Set*_*ter 80 user-interface android android-layout android-constraintlayout

所以最近,与Android Studio 2.2中有一个新的ConstraintLayout,使设计轻松了很多,但不像RelativeLayout并且Linearlayout,我不能使用ScrollView包围ConstraintLayot.这可能吗？如果是这样,怎么样？

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>

尝试添加android:fillViewport="true"到ScrollView.

在这里找到解决方案:LinearLayout不在ScrollView中扩展

NestedScrollView与viewport一起使用true对我有用

<android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true">

        <android.support.constraint.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="700dp">

        </android.support.constraint.ConstraintLayout>

</android.support.v4.widget.NestedScrollView>

ScrollViews中存在ConstraintLayout的错误,并且已修复.谷歌修复了Android Studio 2.2 Preview 2中的错误(constraintlayout 1.0.0-alpha2).

检查此链接是否有新更新(预览2):在ScrollView和RecycleView中正常工作

看起来他们没有解决它.它仍然无法在生产版本中使用 (7认同)
可以确认.即使在2.3.3中也不固定. (3认同)

不要忘记，如果您将某些视图的底部约束到约束布局的底部。Scrollview 无法滚动。

NestedScrollView与使用android:fillViewport="true"

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <!--Edit your stuff-->

    </android.support.constraint.ConstraintLayout>

</android.support.v4.widget.NestedScrollView>

设置ScrollView layout_height为a wrap_content然后它将正常工作.以下是可以帮助某人的例子.我用于compile 'com.android.support.constraint:constraint-layout:1.0.2'约束布局.

为什么ScrollView内部和外部有ConstraintLayout？ScrollView应该是内部带有ConstraintLayout的根元素吗？ (2认同)

尝试为您的约束布局提供一些填充底部，如下所示

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/top"
        android:fillViewport="true">

        <android.support.constraint.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingBottom="100dp">
        </android.support.constraint.ConstraintLayout>

任何将以下属性设置为

滚动视图：：android:fillViewport="true"

约束布局： android:layout_height="wrap_content"

并且它仍然不起作用然后确保您没有将内部可滚动布局（RecycleView）底部约束设置为父级的底部。

添加以下代码行：

android:nestedScrollingEnabled="false"
android:layout_height="wrap_content"
