J2ME中如何用上下键去控制显示图片的不同位置

Answer 1

我给你举个向上运动的例子
protected void keyPressed(int keyCode) {
int gameCode = this.getGameAction(keyCode);
if (gameCode == Canvas.UP||keyCode==Canvas.KEY_NUM2) {
keyUp = true;
}
}
protected void keyReleased(int keyCode) {

int gameCode = this.getGameAction(keyCode);
if (gameCode == Canvas.UP||keyCode==Canvas.KEY_NUM2) {
keyUp = false;
}

你看明白了吗 把返回的keyCode 值等于Canvas对应的键就可以了。
