有人可以帮我添加左右按钮到这个图像流组件吗？目前它使用图像左右导航但我似乎能理解如何将按钮与动作脚本相关联？ 我没有做太多的闪光工作，所以任何帮助都会非常感激。

在舞台上添加两个按钮。
为他们提供btn1和btn2的实例名称（或您选择的任何名称）
添加以下代码
btn1.onPress = function () {
flow.title.text="";
if (ActivePicture==xml.firstChild.childNodes.length-1){
ActivePicture=0;
}else{
ActivePicture++;
}
}
btn2.onPress = function () {
flow.title.text="";
if (ActivePicture<=0){
ActivePicture=xml.firstChild.childNodes.length-1;
}else{
ActivePicture--;
}
}
您的按钮每次递增或递减ActivePicture 1。如果ActivePicture超过图片数量，则会更改为第一张图片。如果ActivePicture低于图片数量，则转到最后一张图片。
