Android application: portrait phone, but viewing a landscape camera

Question

I am new to java and android development. I am developing an application with a camera view in a frameLayout window. My application is intended for orientation in portrait orientation, but the window is in landscape mode, as shown in the figure>. As usual, viewing the default camera in the landscape, so I do camera.setDisplayOrientation (90); to rotate it.

My problem is that when I rotate the image in portrait mode in the landscape window, it is distorted (Pinched). can any1 help me solve this problem, can any1 provide me with a solution to crop borders to achieve the required ratio.

! Im a new user for stackoverflow, so m is not allowed to upload image to others, I can show u.

code:
