嗯，非常感谢。我是看了Radio的代码，

```
/* select a station from list */
struct station_item* station_list_select(struct station_list* list, struct rtgui_workbench* workbench)
{
	rt_size_t index;
	rtgui_rect_t rect;
	rtgui_list_view_t *view;
	struct rtgui_list_item* items;
	struct station_item* station;
	char exit_str[] = "返回..";

RT_ASSERT(list != RT_NULL);
	RT_ASSERT(workbench != RT_NULL);

station = RT_NULL;

items = (struct rtgui_list_item*) rt_malloc (sizeof(struct rtgui_list_item) * (list->count + 1));
	if (items == RT_NULL) return RT_NULL; /* no memory */

/* create view */
	rtgui_widget_get_rect(RTGUI_WIDGET(workbench), &rect);
	view = rtgui_list_view_create(items, list->count + 1, &rect);

items[0].image = RT_NULL;
	items[0].action = station_list_selected;
	items[0].name = exit_str;
	items[0].parameter = view;

for (index = 1; index < list->count + 1; index ++)
	{
		items[index].image = RT_NULL;
		items[index].action = station_list_selected;
		items[index].name = list->items[index - 1].title;
		items[index].parameter = view;
	}

/* add view to workbench */
	rtgui_workbench_add_view(workbench, RTGUI_VIEW(view));

/* show view as modal */
	if (rtgui_view_show(RTGUI_VIEW(view), RT_TRUE) == RTGUI_MODAL_OK)
	{
		station = &list->items[view->current_item - 1];
	}

/* destroy view */
	rtgui_list_view_destroy(view);

return station;
}
```

发现items没有释放，所以有此一问。这么说Radio的代码应该加一句rt_free(items)?
