Is it possible to scroll a ScrollView with a ConstraintLayout in Blueprint Mode?


So I have been developing this layout using a ConstraintLayout inside a ScrollView. It works fine, but now I have hit a problem. I have to expand the layout outside the screen. I can scroll in Design mode, but I cannot add anything without it getting stuck to the top. The constraints are for earlier objects, not the current one I'm adding.

I can add constraints in Blueprint mode, but it looks like I cannot scroll the ScrollView in blueprint mode. Is this even possible? Using Android Studio 2.2(release) and constraint-layout:1.0.0-alpha8

I tried doing it like in Design mode, but it doesn't scroll. Any ideas?

Scrolling normally with ConstraintLayout causes the constraints to stay in the same location.

EDIT:

Updated to alpha9 but still does not solve it

EDIT 2:

beta1 does not work either. AS 2.2.2.

EDIT 3:

Sample layout:

<Button
    android:text="Button"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/sampleButton"
 />

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:ignore="HardcodedText">

    <android.support.constraint.ConstraintLayout

        android:orientation="vertical" android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <!-- ETC constraints -->
    </android.support.constraint.ConstraintLayout>
</ScrollView>


Solution

  • As of ConstraintLayout 1.0.1 scrolling scrolls the constraints. Meaning it is possible to scroll a ConstraintLayout in blueprint mode and it functions as expected. It works at Android Studio 2.3.2 and up (I haven't older versions).

    Now when scrolling, both the visible view, the border, and constraints move along with the drawn button.
