 6         super.onCreate(savedInstanceState);
 7         setContentView(R.layout.sampleadapter_layout);
 8         mListview = (ListView) findViewById(R.id.listview_sample);
 9         SimpleAdapter adapter = new SimpleAdapter(this,
10                 getData(),  //数据来源
11                 R.layout.item_listview, //对应item view
12                 new String[]{"img","title","info"}, //data 中对应值
13                 new int[]{R.id.img,R.id.title,R.id.info});  //填充layout位置
14         mListview.setHeaderDividersEnabled(true);      //是否显示头view 的分割线
15         View header = View.inflate(this,R.layout.listview_header,null);
16         View footer = View.inflate(this,R.layout.listview_header,null);
17         mListview.addHeaderView(header);    //添加头部view
18         mListview.addFooterView(footer);     //添加底部view
19         mListview.setAdapter(adapter);
20     }

27         List<Map<String,Object>> items = new ArrayList<Map<String, Object>>();
28         for (int i = 0; i < 5; i++) {
29             Map<String,Object> item = new HashMap<String,Object>();
30             item.put("img",R.mipmap.ic_launcher);
31             item.put("title","title -- " + i );
