     android:orientation="horizontal">
         <ListView
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:divider="#7f00"　　　　//分割线
             android:dividerHeight="2dp"
             android:id="@+id/listview_sample"/>
 </LinearLayout>

Java 代码：

 public class SampleAdapterActivity extends Activity {

     private ListView mListview;
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.sampleadapter_layout);
         mListview = (ListView) findViewById(R.id.listview_sample);
         SimpleAdapter adapter = new SimpleAdapter(this,
                 getData(),  //数据来源
                 R.layout.item_listview, //对应item view
                 new String[]{"img","title","info"}, //data 中对应值
                 new int[]{R.id.img,R.id.title,R.id.info});  //填充layout位置
         mListview.setHeaderDividersEnabled(true);      //是否显示头view 的分割线
         View header = View.inflate(this,R.layout.listview_header,null);
         View footer = View.inflate(this,R.layout.listview_header,null);
         mListview.addHeaderView(header);    //添加头部view
         mListview.addFooterView(footer);     //添加底部view
         mListview.setAdapter(adapter);
     }

     @Override
     protected void onResume() {
         super.onResume();
     }
     private List<? extends Map<String,?>> getData() {
         List<Map<String,Object>> items = new ArrayList<Map<String, Object>>();
         for (int i = 0; i < 5; i++) {
             Map<String,Object> item = new HashMap<String,Object>();
             item.put("img",R.mipmap.ic_launcher);
             item.put("title","title -- " + i );
             item.put("info","info -- " + i );
             items.add(item);
         }
         return items;
