列表视图调用另一个视图不成功
我用一个列表视图调用另一个视图就是没有变化，搞两个星期了。本人很菜，有高人指点下：我先这样写：

第一个页面出来了，且按上下按键能够上下移动。但按回车键，页面不变。
改成（列表内容与之对应）
void function_sketchpad1(struct rtgui_widget* widget, void* paramter)
{
rt_kprintf("列表1\n");
}
void function_sketchpad2(struct rtgui_widget* widget, void* paramter)
{
rt_kprintf("列表2\n");
}
、、、、、、
按下回车键串口无输出！有高人指点下呗，多谢 void function_action(void* parameter)
{
return;
}
这个函数的入口参数是错的；
我这边能够更改，可以显示出（为了显示清晰，我加了个label）：
