SimpleAdapter是扩展性最好的适配器,可以定义各种你想要的布局,而且使用很方便
SimpleAdapter(Context context, List<? extends Map<String, ?>> data, int resource, String[] from, int[] to)
参数context:上下文,比如this。关联SimpleAdapter运行的视图上下文
参数data:Map列表,列表要显示的数据,这部分需要自己实现,如例子中的getData(),类型要与上面的一致,每条项目要与from中指定条目一致
参数resource:ListView单项布局文件的Id,这个布局就是你自定义的布局了,你想显示什么样子的布局都在这个布局中。这个布局中必须包括了to中定义的控件id
参数 from:一个被添加到Map上关联每一个项目列名称的列表,数组里面是列名称
参数 to:是一个int数组,数组里面的id是自定义布局中各个控件的id,需要与上面的from对应
