How to make background of BrowserField transparent in Blackberry

问题

I am using BrowserField component of RIM BB. It is right now displaying a white background. I want make a transparent background, so it could match with the Manager's background color.

I had tried with below code. But it's not working.

BrowserField contentField = new BrowserField();
bgTransparent = BackgroundFactory.createSolidTransparentBackground(0xffffff, 0);    
contentField.setBackground(bgTransparent);

How to solve this?
