Java ME scorecard with vector and multiple input fields/screens
- by proximity
I have made a scorecard with 5 holes, for each a input field (shots), and a image is shown. The input should be saved into a vector and shown on each hole, eg. hole 2: enter shots, underneath it "total shots: 4" (if you have made 4 shots on hole 1). In the end I would need a sum up of all shots, eg.
Hole 1: 4
Hole 2: 3
Hole 3: 2 ...
Total: 17
Could someone please help me with this task?
{
f = new Form("Scorecard");
d = Display.getDisplay(this);
mTextField = new TextField("Shots:", "", 2, TextField.NUMERIC);
f.append(mTextField);
mStatus = new StringItem("Hole 1:", "Par 3, 480m");
f.append(mStatus);
try { Image j = Image.createImage("/hole1.png");
ImageItem ii = new ImageItem("", j, 3, "Hole 1");
f.append(ii);
}
catch (java.io.IOException ioe) {}
catch (Exception e) {}
f.addCommand(mBackCommand);
f.addCommand(mNextCommand);
f.addCommand(mExitCommand);
f.setCommandListener(this);
Display.getDisplay(this).setCurrent(f);
}
public void startApp()
{
mBackCommand = new Command("Back", Command.BACK, 0);
mNextCommand = new Command("Next", Command.OK, 1);
mExitCommand = new Command("Exit", Command.EXIT, 2);
}
public void pauseApp() { }
public void destroyApp(boolean unconditional) { }
public void commandAction(Command c, Displayable d) {
if (c == mExitCommand) {
destroyApp(true);
notifyDestroyed();
}
else if ( c == mNextCommand) {
// -> go to next hole input! save the mTextField input into a vector.
}
}
