1.Deal with menu command event
MIDlet:
public class TestMIDlet extends MIDlet{
…
protected void startApp() throws MIDletStateChangeException {
ActionController controller = ActionController.getInstance(true);
controller.registerViewer(this); //Register the MIDlet
MyKGameCanvas mgc = new MyKGameCanvas("MYGC"); //Create a GameCanvas
KCommand kc = new KCommand("TEST BUTTON", Command.HELP,1,"MYCMD",null);
mgc.addCommand(kc);
mgc.setCommandListener(controller);
Display.getDisplay(this).setCurrent(mgc);
}
…
}
MyGameCanvas:
public class MyKGameCanvas extends KGameCanvas{
public MyKGameCanvas(String uniqueID) {
super(uniqueID);
}
public void showString(String string){
Graphics g = this.getGraphics();
g.setColor(0xFFFFFFFF);
g.fillRect(0, 0, this.getWidth(), this.getHeight());
g.setColor(0xFF000000);
g.drawString(string, 0, 0, Graphics.TOP|Graphics.LEFT);
this.flushGraphics();
}
}
Action:
public class TestAction implements Action{
public void excute(KCommand cmd, Item item, Displayable dis, ActionForward forward,Hashtable parameters) {
MyKGameCanvas mkc = ((MyKGameCanvas)dis);
mkc.showString("hello world! From "+mkc.getUniqueID()+"."+cmd.getUniqueID());
}
}
Specify the Action in config file:
DEBUG=true //open the debug model of KBOX
CMD.MYCMD.ACTION=action.TestAction
Key pressed Action:
public class TestKeyAction implements Action{
public void excute(KCommand cmd, Item item, Displayable dis, ActionForward forward,Hashtable parameters) {
MyKGameCanvas mkc = ((MyKGameCanvas)dis);
…
Do your business here.
..
}
}
Specify the action of event
DEBUG=true //open the debug model of KBOX
CMD.MYCMD.ACTION=action.TestAction
KEY.MYGC.FIRE.ACTION=action.TestKeyAction…
...
KCommand kc = new KCommand("TEST BUTTON", Command.HELP,1,"MYCMD").setAttribute("parameter","Hello world!");
...
4.Parameter passing from configuration file :
Configuration file:
...
CMD.MYCMD.ACTION=action.TestAction
CMD.MYCMD.PARAMETERS.1=HELLO
CMD.MYCMD.PARAMETERS.2=WORLD
...
Action:
...
public void excute(KCommand cmd, Item item, Displayable dis, ActionForward forward,Hashtable parameters) {
...
System.out.println(parameters.get("1"));//HELLO
System.out.println(parameters.get("2"));//HELLO
...
}
...
note: the parameter name in configuration file must be 1,2,3....
5.Application internationalization:
MsgResource msgRes = MsgResource.getInstance();
msgRes.loadRes(); //Call when it's the first time to use MsgResource
Form form = new Form(msgRes.getMsg("title"));
Edit res.propery:
title=HELLO TITLE!
