按键事件！

/**
* summary:捕获当前按键菜单上IDX

protected void keyPressed(int code)
{
if(getGameAction(code) == Canvas.UP && menuIDX-1 >=0 )
{
menuIDX--;
System.out.println(Canvas.UP);
}
if(getGameAction(code) == Canvas.DOWN && menuIDX+1 < mainMenu.length)
{
menuIDX++;
System.out.println(menuIDX);
}
switch(Canvas.FIRE = menuIDX)
{
case 0:
//SCanvas sc = new SCanvas();
//sc.start();
case 1:
case 2:
case 3:
case 4:
}
}
我想键模拟器中间键(FIRE) 来启动另外个类对象！ 想了很久，弄了忒久， 没弄好！望大家指点...

如果你不建议代码结构，无所谓代码是否好看，那你就直接写就是了。
不过还是建议你通过改变"state"来控制。 仅供参考：

另外： 一个MIDLET最好就有一个CANVAS！！！

switch(Canvas.FIRE = menuIDX)
{
case 0:
//SCanvas sc = new SCanvas();
//sc.start();
gameState = GAME_START; // GAME_STATE = 1 IS A STATIC FINAL INT.
break;
case 1:
gameState = GAME_PAUSE;
break;
case 2:
case 3:
case 4:
}

// gameUpdata function should be called in run()
private void gameUpdata()
{
switch(gameState)
{
case GAME_START:
changeState(GAME_INITIALISE);
break;
......
}
}

private void changeState(int nextState)
{
switch(nextState)
{
case GAME_INITIALISE:
//TODO: for example --> initialise game res;
break;
}

gameState = nextState;
}

public void run()
{
while(!stopGame)
{
gameUpdata();
}
}

GameCanvas是吧
你上下键都知道用
getGameAction(code)== Canvas.UP
getGameAction(code) == Canvas.DOWN
中键也这样用就好了。
然后判断下当前的IDX等于多少，启动相应事件就好了

如果要是做菜单的话可以找J2SE的源码来看看，怎么映射比较合理

根据你的意思，修改了一下。楼主可以试试是否好使。

/** 
* summary:捕获当前按键菜单上IDX 
*/ 
protected void keyPressed(int code)
{
    if (getGameAction(code) == Canvas.UP && menuIDX-1 >=0) {
        if (menuIDX - 1 >= 0) {
            menuIDX--;
        }
        System.out.println(Canvas.UP);
    } else if (getGameAction(code) == Canvas.DOWN) {
        if (menuIDX + 1 < mainMenu.length) {
            menuIDX++;
        }
        System.out.println(menuIDX);
    } else if (getGameAction(code) == Canvas.FIRE) {
        switch (menuIDX) {
            case 0:    
            //SCanvas sc = new SCanvas(); 
            //sc.start(); 
            case 1:
            case 2:
            case 3:
            case 4:
        }
    }
}

修正下上边的笔误

/** 
* summary:捕获当前按键菜单上IDX 
*/ 
protected void keyPressed(int code)
{
    if (getGameAction(code) == Canvas.UP) {
        if (menuIDX - 1 >= 0) {
            menuIDX--;
        }
        System.out.println(Canvas.UP);
    } else if (getGameAction(code) == Canvas.DOWN) {
        if (menuIDX + 1 < mainMenu.length) {
            menuIDX++;
        }
        System.out.println(menuIDX);
    } else if (getGameAction(code) == Canvas.FIRE) {
        switch (menuIDX) {
            case 0:    
            //SCanvas sc = new SCanvas(); 
            //sc.start(); 
            case 1:
            case 2:
            case 3:
            case 4:
        }
    }
}
