问题描述

我需要显示只有一个列表项，列表视图其余项目多文本视图将只有一个TextView的。

I need to show multiple text views in only one list item and the rest of the list view items will have just one textview.

请自己的适配器：

BaseAdapter已经防阻方法不同视图类型的工作（用于列表项的细胞不同的布局）和ef​​fektivly回收意见：

BaseAdapter already provieds methods for working with different View types (different layout for list item cells) and to effektivly recycle views:

• getViewTypeCount（）：多种不同的视图（布局）如何present计数。



• getItemViewType（）：返回一个整数，以确定在所述小区中的项目的视图类型。注意内部BaseAdapter实现使用数组。因此，在这里你的返回值必须是从0到n。你不允许跳过索引。

• getViewTypeCount(): The count of how many different Views (layouts) are present.

• getItemViewType(): Returns a integer to identify the view type of the item in the cell. Note the internally BaseAdapter implementation uses an array. Therefore your values returned here must be from 0 to n. You are not allowed to skip indexes.
