Android Study，ListView升级使用，支持图片等展现

1、实现ListView布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/lsvShow"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >
    </ListView>

</LinearLayout>

2、实现ListView的Item布局，支持图片等展现

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     android:layout_width="match_parent"
 4     android:layout_height="match_parent"
 5     android:orientation="horizontal" >
 6 
 7     <ImageView
 8         android:id="@+id/icon"
 9         android:layout_width="wrap_content"
10         android:layout_height="wrap_content" />
11 
12     <TextView
13         android:id="@+id/name"
14         android:layout_width="wrap_content"
15         android:layout_height="wrap_content" />
16 
17     <TextView
18         android:id="@+id/info"
19         android:layout_width="wrap_content"
20         android:layout_height="wrap_content" />
21 
22     <CheckBox
23         android:id="@+id/check"
24         android:layout_width="wrap_content"
25         android:layout_height="wrap_content" />
26 
27 </LinearLayout>

3、实现展现逻辑

 1 public class ListViewActivity extends Activity {
 2 
 3     private ListView _lsvShow;
 4 
 5     @Override
 6     protected void onCreate(Bundle savedInstanceState) {
 7         // TODO Auto-generated method stub
 8         super.onCreate(savedInstanceState);
 9 
10         setContentView(R.layout.view_listview);
11 
12         _lsvShow = (ListView) findViewById(R.id.lsvShow);
13 
14         generatorImageItem();
15     }
16 
17     private void generatorImageItem() {
18 
19         ArrayList<HashMap<String, Object>> dataSource = new ArrayList<HashMap<String, Object>>();
20         for (int i = 0; i < 10; i++) {
21 
22             HashMap<String, Object> hashMap = new HashMap<String, Object>();
23             hashMap.put("icon", R.drawable.ic_launcher);
24             hashMap.put("name", "小伙伴" + i);
25             hashMap.put("info", "，小伙伴们都惊呆了！");
26             dataSource.add(hashMap);
27         }
28 
29         SimpleAdapter adapter = new SimpleAdapter(this, dataSource,
30                 R.layout.body_listview_image_item, new String[] { "icon",
31                         "name", "info" }, new int[] { R.id.icon, R.id.name,
32                         R.id.info });
33 
34         _lsvShow.setAdapter(adapter);
35     }
