3 activity_main.xml的文件内容
<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"

4 listview_item.xml的文件内容

</linearlayout>
5 mainactivity的内容如下：

import java.util.list;
import java.util.map;
import android.os.bundle;

setcontentview(r.layout.activity_main);
listview mlistview = (listview) findviewbyid(r.id.listview);
list<map<string, object>> data = new arraylist<map<string,object>>();
map<string, object> map = new hashmap<string,object>();
map.put("name", "张三1");

data.add(map);
map = new hashmap<string,object>();
map.put("name", "张三2");
map.put("icon", r.drawable.f007);
data.add(map);
map.put("name", "张三3");
map.put("name", "张三4");
map.put("name", "张三5");
simpleadapter adapter = new simpleadapter(
this, //上下文

r.layout.listview_item, //listview的子条目的布局的id
new string[]{"name","icon"}, //data数据中的map集合里的key
new int[]{r.id.tv_name,r.id.iv_icon}); //resource中的id

}
}
