The BlackBerry device supports multiple fonts in various sizes. These fonts can be used in custom BlackBerry applications and can be changed during runtime. The number of fonts available on a device depends on the model and the BlackBerry Device Software version installed.
The following example illustrates how to use fonts in a custom BlackBerry application and change the font during runtime:
import net.rim.device.api.ui.*; import net.rim.device.api.ui.component.*; import net.rim.device.api.ui.container.*; import net.rim.device.api.system.*; public final class FontChange extends UiApplication { private Font font; //Get all fonts available on the BlackBerry private FontFamily fontFamily[] = FontFamily.getFontFamilies(); public static void main(String[] args) { FontChange theApp = new FontChange(); theApp.enterEventDispatcher(); } public FontChange() { MainScreen mainScreen; FontChangeListener fontChangeListener = new FontChangeListener(); //Set the current font to the first in the font list. font = fontFamily[0].getFont(FontFamily.SCALABLE_FONT, 10); Font.setDefaultFont(font); mainScreen = new MainScreen(); //Set the title of the mainscreen. LabelField title = new LabelField("Font Test Example", LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH); mainScreen.setTitle(title); ObjectChoiceField pickFont = new ObjectChoiceField("Select a font:", fontFamily, 0); pickFont.setChangeListener(null); pickFont.setChangeListener(fontChangeListener); mainScreen.add(pickFont); mainScreen.add(new SeparatorField()); //RichTextField that displays text in the specified colour. RichTextField fontText = new RichTextField ("The quick red fox jumps over the lazy brown dog.") { public void paint(Graphics graphics) { //Change the colour of the text in the RichTextField to green. graphics.setColor(0x00008800); super.paint(graphics); } }; mainScreen.add(fontText); //Display the main screen pushScreen(mainScreen); } //Create a custom FieldChangeListener that will change the current font //to what is selected in the ObjectChangeField. class FontChangeListener implements FieldChangeListener { public void fieldChanged(Field field, int context) { //If the ObjectCoiceField has changed if (field instanceof ObjectChoiceField) { //Get the new font selected in the ObjectChoiceField and set the //current font to match what is selected. ObjectChoiceField choiceField = (ObjectChoiceField)field; font = fontFamily[choiceField.getSelectedIndex()].getFont (FontFamily.SCALABLE_FONT,10); Font.setDefaultFont(font); } } } } |
Tq for your info :)
ReplyDeleteCan u give me some example about change the font colour?
Hello Stephanie,
ReplyDeleteAs you can see in above example :
public void paint(Graphics graphics)
{
//Change the colour of the text in the
//RichTextField to green.
graphics.setColor(0x00008800);
super.paint(graphics);
}

paint() method is used to change the font color. You can change font color for any field by the same as above.
I have a BlackBerry Curve 8520. I was trying to find a way to change the font from black to a color for texting. Everywhere I look it talks about background color. I know about the themes. The theme colors only color the numbers when dialing. I want to be able to download an application that will allow me to customize the the color of the font. Here is an example of what I am talking about. What I am writing,I want it to be in the color of my choice. How do I go about getting help with finding an application that will do that?
ReplyDeleteI am trying to find the same as Amy. The only thing I have found is Empower SMS, however, it's not compatible with os 5.0. I too am using a curve 8520. Any idea how to install new fonts and colors? As for the code above, I am new to the java programming world. Can you give a little more detail on how to initiate this code? I have one of the java programs for bb app development, but currently I'm using JCreator for the sake of learning more before I even try jumping in on this. Help?? Please?? :(
