android中ListView控件

今天学习了ListView控件和页面跳转，下面大致介绍下：

第一步：创建显示内容的文件vlist.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:background="#31B6E7" >
    
    <ImageView android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="5px" />
    
    <LinearLayout android:orientation="vertical"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <TextView android:id="@+id/txtid"
            android:layout_width="0dp"
            android:layout_height="0dp"/>
        <TextView android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#FFFFFF"
            android:textSize="22px"/>
        <TextView android:id="@+id/info"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#FFFFFF"
            android:textSize="13px"/>
        
    </LinearLayout>
</LinearLayout>

下面是主Activity:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:id="@+id/txtDescription"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <LinearLayout
        android:id="@+id/tab1"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <ListView
            android:id="@+id/listView1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:layout_weight="1" >
        </ListView>
    </LinearLayout>

</RelativeLayout>

下面是对应的代码：

private void bindData() {
        ListView lv = (ListView)findViewById(R.id.listView1);

        SimpleAdapter adapter= new SimpleAdapter(this, getData(), R.layout.vlist, 
                new St ring[]{"id","img","title","info"},
                new int[]{R.id.txtid, R.id.img,R.id.title,R.id.info});
        lv.setAdapter(adapter);
                      
        lv.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) {
                // TODO Auto-generated method stub
                ListView listView = (ListView)arg0;
                HashMap<String, String> map = (HashMap<String, String>)listView.getItemAtPosition(arg2);
                String id = map.get("id");
                String info = map.get("info");
                
                TextView txtDescription = (TextView)findViewById(R.id.txtDescription);
                StringBuilder sb = new StringBuilder();
                sb.append(getResources().getText(R.string.detail));
                sb.append(":"+info);
                sb.append("-----id:"+id);
                txtDescription.setText(sb);
            }
        });        
    }
    private List<Map<String, Object>> getData() {
        List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();

        Map<String, Object> map = null;
        for (int i = 0; i < 10; i++) {
            map =  new HashMap<String, Object>();
            map.put("id", i);
            map.put("title", "Title");
            map.put("info", "google "+(i+1));
            map.put("img", R.drawable.ic_action_search);
            list.add(map);
        }
        return list;
    }
