How to programmatically change SurfaceView orientation

Question

We need our android app to support Android V2.3 through to V5. We are rendering a Surface view inside a LinearLayout. Our Activity is locked to portrait.

We would like to programmatically rotate the SurfaceView with the same effect as though it changed from Portrait to Landscape. The SurfaceView is dynamically created in code and added to the LinearLayout which is defined in the xml. We wish to keep other views the same, this is why we need to fix the Activity orientation. How do we go about this?

EDIT

Wherever you use sthe camera, set the orientation to 90 degrees:

  mCamera = Camera.open();
  mCamera.setDisplayOrientation(90);

Hi, It is not the camera surface view I have the problem rotating. It is rendered Surface view of video from remote end – tech74 May 23 '15 at 22:03
RotateAnimation rotate= new RotateAnimation(0.0f, 90.0f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); rotate.setFillAfter(true); remoteSurface.setAnimation(rotate); – tech74 May 23 '15 at 22:04
Have you tried adding the rotation attr on the surface view in your layout xml? – user2520215 May 23 '15 at 22:12
I create the SurfaceView dynamically and add it to a LinearLayout – tech74 May 23 '15 at 22:36
Does this work: surfaceViewObject.setrotation(90); ? – user2520215 May 23 '15 at 22:38
Video stops playing when I do that, just black view now – tech74 May 24 '15 at 04:00
although it appears it rotated – tech74 May 24 '15 at 04:01
