How to maintain camera display orientation in android when i create custom camera class.

 public CameraSurface(Context context) {
        super(context);

        try {
            holder = this.getHolder();
            holder.addCallback(this);
            holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        try {
            // Open the Camera in preview mode
            this.camera = Camera.open();
            this.camera.setPreviewDisplay(holder);
        } catch (IOException ioe) {
            ioe.printStackTrace(System.out);
        }
    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {
        // Surface will be destroyed when replaced with a new screen
        // Always make sure to release the Camera instance
        camera.stopPreview();
        camera.release();
        camera = null;
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width,
            int height) {
        // Now that the size is known, set up the camera parameters and begin
        // the preview.
//      Camera.Parameters parameters = camera.getParameters();
//      System.out.println("height...."+width+" height....."+height);
//      parameters.setPreviewSize(width, height);
//      camera.setParameters(parameters);
//      camera.startPreview();
        Camera.Parameters parameters = camera.getParameters();
        List<Camera.Size> previewSizes = parameters.getSupportedPreviewSizes();

        // You need to choose the most appropriate previewSize for your app
        Camera.Size previewSize;
        if(previewSizes.size() > 1){
            previewSize =previewSizes.get(1);  // .... select one of previewSizes here
        }else{
            previewSize =previewSizes.get(0);
        }
        parameters.setPreviewSize(previewSize.width, previewSize.height);
        camera.setParameters(parameters);
        camera.setDisplayOrientation(90);
        camera.startPreview();
    }
