Rotating a Camera SurfaceView to portrait

Question

I have looked up a few posts on changing the orientation of the camera with a surface view, but I have taken my code from the examples at:

Answer 1

Please try this..

@Override
 public void surfaceChanged(SurfaceHolder holder,
                       int format, int width, int height)
{
// TODO Auto-generated method stub

if(previewing)
{
    camera.stopPreview();
    previewing = false;
}
 Camera.Parameters parameters = camera.getParameters();
      Display display = ((WindowManager)getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
   int or=cameraInfo.orientation;
     // You need to choose the most appropriate previewSize for your app
   // .... select one of previewSizes here
           /* parameters.setPreviewSize(previewSize.width, previewSize.height);*/
   if(display.getRotation() == Surface.ROTATION_0)
    {

    camera.setDisplayOrientation(90);
    or=90;
    }

    if(display.getRotation() == Surface.ROTATION_180)
    {
        camera.setDisplayOrientation(270);
    or=270;
    }
    if(display.getRotation() == Surface.ROTATION_270)
    {
        camera.setDisplayOrientation(180);
        or=180;
    }

  parameters.setRotation(or);

  camera.setParameters(parameters);
 try
{
        camera.setPreviewDisplay(cameraSurfaceHolder);
        camera.startPreview();
        previewing = true;
    }
    catch (IOException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
