Constraint Layout gives error in default template in Android Studio 2.3

Question

I've updated Android Studio 2.3, after that I am getting default ConstrainLayout as template xml.

But in that I have RelativeLayout as Child Layout and I getting following warning.

This view is not constrained, it only has designtime positions, so it will jump to (0,0) unless you add constraints.

The layout editor allows you to place widgets anywhere on the canvas, and it records the current position with design time attributes (such as layout_editor_absoluteX.) These attributes are not applied at runtime, so if you push your layout on a device, the widgets may appear in a different location than shown in the editor. To fix this, make sure a widget has both horizontal and vertical constraints by dragging from the edge connections.

                android:layout_centerHorizontal="true"
                android:layout_centerVertical="true" />

        </RelativeLayout>

    </android.support.constraint.ConstraintLayout>
</layout>

Getting warning on RelativeLayout, What should I do?

Answer 1

Go to Design, right-click on relative layout and select Constraint layout-->Infer Constraints

Answer 2

Drag the object to connect to the walls...Create connections between walls and object

Look at the image example
