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:

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;
   }
