Is it possible to put a ConstraintLayout inside a ScrollView?
AndroidAndroid LayoutUser InterfaceAndroid ConstraintlayoutAndroid Problem Overview
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?
i.e.
<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>
Android Solutions
Solution 1 - Android
Try adding android:fillViewport="true"
to the ScrollView.
Found the solution here: https://stackoverflow.com/questions/2599837/linearlayout-not-expanding-inside-a-scrollview
Solution 2 - Android
There was a bug with ConstraintLayout inside ScrollViews and it has been fixed. google has fixed the bug in Android Studio 2.2 Preview 2 (constraintlayout 1.0.0-alpha2).
Check this link for new update (Preview 2): works properly inside ScrollView and RecycleView

Edit - 09/16/20:
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.
Solution 3 - Android
use NestedScrollView
with viewport true is working good for me
<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>
Solution 4 - Android
Don't forget that If you constraint some view's bottom to constraint layout's bottom.Scrollview could not scroll.
Solution 5 - Android
Set ScrollView
layout_height
as a wrap_content
then it will work fine. Below are example which may help someone.
I have used compile 'com.android.support.constraint:constraint-layout:1.0.2'
for constraint layout.

Solution 6 - Android
Try giving some padding bottom to your constraint layout like below
<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>
</ScrollView>
Solution 7 - Android
Anyone who has set below property to
ScrollView:: android:fillViewport="true"
constraint layout: android:layout_height="wrap_content"
And it's still not working then make sure then you have not set the Inner scrollable layout (RecycleView) bottom constraint to bottom of the parent.
Add below lines of code:
android:nestedScrollingEnabled="false"
android:layout_height="wrap_content"
Make sure to remove below constraint:
app:layout_constraintBottom_toBottomOf="parent"
Full code
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<androidx.constraintlayout.widget.ConstraintLayout
android:id="@+id/selectHubLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context=".ui.hubs.SelectHubFragment">
<include
android:id="@+id/include"
layout="@layout/signup_hub_selection_details"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/rv_HubSelection"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:nestedScrollingEnabled="false"
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="1.0"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/include" />
</androidx.constraintlayout.widget.ConstraintLayout>
Solution 8 - Android
Use NestedScrollView
with 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>
Solution 9 - Android
Since the actual ScrollView
is encapsulated in a CoordinatorLayout
with a Toolbar
...
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
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">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
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="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<include layout="@layout/list"/>
</android.support.design.widget.CoordinatorLayout>
... I had to define android:layout_marginTop="?attr/actionBarSize"
to make the scrolling working:
<?xml version="1.0" encoding="utf-8"?>
<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="wrap_content"
android:layout_marginTop="?attr/actionBarSize">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<!-- UI elements here -->
</android.support.constraint.ConstraintLayout>
</ScrollView>
Above also works with NestedScrollView
instead of ScrollView
.
Defining android:fillViewport="true"
is not needed for me.
Solution 10 - Android
I've spent 2 days attempting to convert layouts to ConstraintLayout
in the so-called "stable" release Android Studio 2.2 and I've not got ScrollView
to work in the designer. I'm not going to start down the route of adding constraints in XML for Views
that are further down the scroll. After all this is supposed to be a visual design tool.
And the number of rendering errors, stack overflows and theme issues I've had has led me to conclude that the whole ConstraintLayout
implementation is still riddled with bugs. Unless you are developing simple layouts then I'd leave it well alone until it's had a few more iterations at least.
That's 2 days I'm not going to get back.
Solution 11 - Android
I had NestedScrollView inside ConstraintLayout, and this NestedScrollView has one ConstraintLayout.
If you're facing issue with NestedScrollView
,
add android:fillViewport="true"
to NestedScrollView, worked.
Solution 12 - Android
PROBLEM:
I had a problem with ConstraintLayout and ScrollView when i wanted to include it in another layout.
DECISION:
The solution to my problem was to use dataBinding.
Solution 13 - Android
Don't forget about tools:context=".YouClassName"
property in ScrollView
.
It is what was causing my application to crash.
