步聚：
1.建立ListView对象；--（作用：绑定Adapter呈现数据）
2.建立ListView实现的Item栏位.xml布局；--（作用：实现ListView的栏位布局）
3.建立Item.xml 的View数据实例（类）；--（作用：实现Item栏位数据接口）
4.继承BaseAdapter建立MyAdapter类class；--（作用：封装ListView的.xml布局与Item数据）
5.当然还要作更多的操作，这里例出简洁的方法；
adapter实现：
1 private class UpdateAdpter extends BaseAdapter {
2
3 private LayoutInflater mInflater;
4 private List<ItemData> mItemsData;
5
6 public UpdateAdpter(Context context, List<ItemData> listItemData) {
7 this.mInflater = LayoutInflater.from(context);
8 this.mItemsData = listItemData;
9
10 }
11
12 @Override
13 public int getCount() {
14 // TODO Auto-generated method stub
15 return mItemsData.size();
16 }
17
18 @Override
19 public Object getItem(int position) {
20 // TODO Auto-generated method stub
21 return mItemsData.get(position);
22 }
23
24 @Override
25 public long getItemId(int position) {
26 // TODO Auto-generated method stub
27 return position;
28 }
29
30 @Override
31 public View getView(final int position, View convertView,
32 ViewGroup parent) {
33 // TODO Auto-generated method stub
34 ViewHolder holder;
35 if (convertView == null) {
36 convertView = mInflater.inflate(
37 R.layout.activity_account_update_listview_item, null);
38 holder = new ViewHolder(convertView);
39 convertView.setTag(holder);
40
41 } else {
42 holder = (ViewHolder) convertView.getTag();
43 }
44 ItemData item = mItemsData.get(position);
45 holder.title.setText(item.getTitle());
46 holder.price.setText(item.getPrice());
47 holder.text.setText(item.getBuyText());
48 holder.status.setText(item.getStatus());
49
50 return convertView;
51 }
52
53 public class ViewHolder {
54 public TextView title;
55 public TextView price;
56 public TextView buytext;
57 public TextView status;
58
59 ViewHolder(View view) {
60 title = (TextView) view
61 .findViewById(R.id.tv_accountupdateitem_title);
62 price = (TextView) view
63 .findViewById(R.id.tv_accountupdateitem_price);
64 text = (TextView) view
65 .findViewById(R.id.tv_accountupdateitem_buytext);
66 status = (TextView) view.findViewById(R.id.tv_accountupdate_status);
67 }
68 }
69 }
70
71 private class ItemData {
72 private String title;//标题
73 private String price;//价格
74 private String text;//内容
75 private String status;//状态
76
77 public void setTitle(String value) {
78 title = value;
79 }
80
81 public String getTitle() {
82 return title;
83 }
84
85 public void setPrice(String value) {
86 price = value;
87 }
88
89 public String getPrice() {
90 return price;
91 }
92
93 public void setText(String value) {
94 buytext = value;
95 }
96
97 public String getText() {
98 return buytext;
99 }
100
101 public void setStatus(String value) {
102 status = value;
103 }
104
105 public String getStatus() {
106 return status;
107 }
108 }
activity调有实例：
public class UpdateActivity extends Activity implements OnClickListener{
private ListView UpdateLView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_account_update);
iniView();
}
public void iniView() {
UpdateLView = (ListView) findViewById(R.id.account_update_listView);
iniListViewDataUpdate();//初始listview数据
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
private void iniListViewDataUpdate(){
ItemData itemData;
List<ItemData> listItemData = new ArrayList<ItemData>();
for (int i=0;i<2;i++){
itemData= new ItemData();
itemData.setTitle("title");
itemData.setPrice("price");
itemData.setText("text");
itemData.setStatus("status");
listItemData.add(itemData);
}
nowUpdateLView.setAdapter(new UpdateAdpter(this,listItemData));
}
item.xml;
