Constraintlayout 1.0.2 Shows Nothing

I'm still having this weird problem. ConstraintLayout only works when it's on 'alpha-7', when I change it to '1.0.2' the latest version it shows nothing Desired layout should look

Solution 1:

After a year of waiting for a real explanation of what is going on and what happened after 'Alpha-7', I "Kindaaa~"figured it out.

The Short Answer

Activities with ConstraintLayout will do fine. however if you are adding a fragment on top, then make sure to make the activity background transparent.
