Question

I don’t know how to apply font style to a text in a LabelField in Blackberry.

Answer 1

Here’s a post which has a ResponseLabelField that extends LabelField and shows how to set the font:

Here’s a quick code snippet for you:

    LabelField displayLabel = new LabelField("Test", LabelField.FOCUSABLE)
    {
        protected void paintBackground(net.rim.device.api.ui.Graphics g)
        {
            g.clear();
            g.getColor();
            g.setColor(Color.CYAN);
            g.fillRect(0, 0, Display.getWidth(), Display.getHeight());
            g.setColor(Color.BLUE);               
        }
    };  

    FontFamily fontFamily[] = FontFamily.getFontFamilies();
    Font font = fontFamily[1].getFont(FontFamily.CBTF_FONT, 8);
    displayLabel.setFont(font);

Someone correct me if I’m wrong, but I believe different fonts are chosen by using a different index into the fontFamily array.

EDIT: And here’s a test app you can use to switch between fonts: http://blackberry-digger.blogspot.com/2009/04/how-to-change-fonts-in-blackberry.html
