I still have this strange problem. ConstraintLayout only works when it is on alpha-7, when I change it to 1.0.2, the latest version shows nothing
The desired layout should look like this:
However, I get this: "on a real HTC one M9 - CM 12.1.1"
** "Show Layout Boundaries" is turned on so you can see that there is nothing on the device.
** I also tried "Show Layout Update" and it shows nothing.
In the inspector wizard, enter the username, field "Password" and "Login" and show:
XML layout:

repositories { jcenter(); } dependencies { compile 'com.android.support.constraint:constraint-layout:1.0.2' }
Things I tried:
Invalidity and restart of Android studio.
I tried on the emulator.
I tried the Huawei device.
I tried on HTC one device M9.
Returning to Alpha 7 works great.
