Preview picture shows in small layout on tablet


I am having a problem with the picture preview when viewed on my Nexus10 when using the activity_twopane. The picture preview shows compressed into the smaller list portion of the display (fragmentContainer). When I revert back to the old single pane version of the program, I get a full screen preview. When I display the existing photo in the activity_twopane mode, it appears to be full screen. There must be some sort of override or program change to fix this or something I missed, but I have not been able to find it. Using LogCat, when I call mCamera.startPreview() in CrimeCameraFragment surfaceChanged, the camera parameters show a picture size of 2560 width and 1920 height, which is the screen size for Nexus10. Any suggestions would be appreciated. Thanks.
