Is it possible to put a ConstraintLayout inside a ScrollView?

Try adding android:fillViewport="true" to the ScrollView.

Found the solution here: LinearLayout not expanding inside a ScrollView

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

Solution 1:

The solution was to use android:fillViewport="true" on theScrollView

Solution 2:

Use NestedScrollView instead of ScrollView with android:fillViewport="true"

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.

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>
