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

问题

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>

In android studio 2.2 update, it includes scrolling in design and blueprint mode by default. click on design mode in the preview pane and try to scroll your screen it will start scrolling. There is another option of blueprint in that mode it shows you the blueprint of the design and by doing same for this will help you scroll in blueprint mode also.

Put the Scroll view outside of the Constraint layout. Then use this [Red mark] to drag the view and it will make a custom device editor to you. When you have done, change back to the device editor [Beside rotation icon]...

回答3:

In latest android studio 2.2.2 version with constraint-layout:1.0.0-beta1 you can scroll blueprint

for better working, after updating constraint-layout please restart android studio (invalidate caches)

回答4:

Not yet.

Maybe try to have a separate file to edit the content instead, and use an include in the file where you have the ScrollView?

回答5:

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.

beta1 version has been released. I doubt this is fixed, but check it out.

You can ask for a bugfix for this here: http://tools.android.com/feedback

PS: you are trying to scroll using the mouse scroll wheel, right? hehe just checking... I say that because just recently I figured out I could scroll in the design mode using the mouse wheel.. duhh haha. I never tried in blueprint mode though.
