You need to override the onMeasure method of SurfaceView class to get width and height of surfaceview

@Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        final int width = resolveSize(getSuggestedMinimumWidth(), widthMeasureSpec);
        final int height = resolveSize(getSuggestedMinimumHeight(), heightMeasureSpec);
        setMeasuredDimension(width, height);

        if (mSupportedPreviewSizes != null) {
            mPreviewSize = getOptimalPreviewSize(mCamera.getParameters().getSupportedPreviewSizes(), width, height);
        }
    }

Then set the preview size you got to the camera parameters preview size.

cameraParameters.setPreviewSize(mPreviewSize.width, mPreviewSize.height);
mCamera.setParameters(cameraParameters);

getSuggestedMinimumHeight(), getSuggestedMinimumWidth() are the methods of View class

Hope this helps !!!
