CameraView - match_parent issue - Urgent!

[Wang-Jong]

First of all, I say this is a great library.
With the help of this, I can easily implement a custom camera view in my application.
Here is my problem.

I'd like to show a full-screen preview window.
When camera view height is set wrap_content, it works well.
But when it is match_parent, the taken picture is different from what it is shown in the preview window.
It's pushed a little to the left.
I did everything I can. I set adjustViewBounds to true, aspectRatio to 16:9, but it doesn't work.

Can anybody help me fix this issue?
Any suggestion will be appreciated.

I need your help.
