先上张效果图：
1,思路简述
这个肯定是要重写 baseAdapter的了，这里我分了两个数据适配器，一个是自定义的 listView的item 风格xml，另一个是该风格xml文件里面的嵌套的GridView数据适配。然后我们需要两个数据辅助类，类似上述，一个是专门来保存在GridView中要显示的每张图片的信息，例如它的url、name、id等等，暂称该辅助类为 UserImgs，大家可以随便增删，另一个是总的专门保存listView中的item的数据，我们称它为UserInfo，这里，说明下，因为每条 item 都有一个自己的GridView，也就是说，UserInfo中必须要有一个UserImgs类实例，用来存储图片信息。然后，就是代码实现了。
使用例子放置最后。
2,辅助类的代码
声明，这两个辅助类，是我根据自己项目所定义的，大家可以据己所需，自行修改，思路掌握了，修改很简单、很快！
第一个，UserImgs
1 package cn.share.bananacloud.custom_listview_style;View Code
2
3 /**
4 * Created by Administrator on 2015/9/6.
5 */
6 public class UserImgs {
7
8 public int id; //图片的id
9 public String name; //图片的名称
10 public String urls; //图片的 url
11
12 public int getId() {
13 return id;
14 }
15 public void setId(int id) {
16 this.id = id;
17 }
18 public String getName() {
19 return name;
20 }
21 public void setName(String name) {
22 this.name = name;
23 }
24 public String getUrls() {
25 return urls;
26 }
27 public void setUrls(String urls) {
28 this.urls = urls;
29 }
30 }
第二个，UserInfo
1 package cn.share.bananacloud.custom_listview_style;View Code
2
3 /**

6 * email:913337456@qq.com
7 */
8 import java.util.ArrayList;
9 import java.util.List;
10 public class UserInfo {
11 private String headUrl; // 头像 url
12 private String usertext; // 帖子内容
13 private String username; // 用户名称
14 private String usertime; // 发帖时间
15 private String usertalknumber; // 评论数目
16 private List<UserImgs> ui = new ArrayList<UserImgs>(); // 这个就是我说的，UserImgs 实例
17 //--------------------------------------- headUrl
18 public String getHeadUrl() {
19 return headUrl;
20 }
21
22 public void setHeadUrle(String headUrl) {
23 this.headUrl = headUrl;
24 }
25 //--------------------------------------- Name
26 public String getUserName() {
27 return username;
28 }
29
30 public void setUserName(String username) {
31 this.username = username;
32 }
33 //--------------------------------------- Text
34 public String getUserText() {
35 return usertext;
36 }
37
38 public void setUserText(String usertext) {
39 this.usertext = usertext;
40 }
41 //---------------------------------------- Time
42 public String getUserTime() {
43 return usertime;
44 }
45
46 public void setUserTime(String usertime) {
47 this.usertime = usertime;
48 }
49 //---------------------------------------- TalkNumber
50 public String getUserTalkNumber() {
51 return usertalknumber;
52 }
53
54 public void setUserTalkNumber(String usertalknumber) {
55 this.usertalknumber = usertalknumber;
56 }
57 //---------------------------------------- post pics and mp3 or mp4
58 public List<UserImgs> getUi() {
59 return ui;
60 }
61 public void setUi(List<UserImgs> ui) {
62 this.ui = ui;
63 }
64 }
3,ListView 的数据适配的重写类
声明，这个例子和下面的例子的图片显示都采用了开源框架---imageLoder。这个数据适配器是 GridView的数据适配入口，GridView的数据适配在它里面调用配置，必要的代码注释我已给出，其他的都很容易理解。

4,GridView 数据适配器的重写类
GridView 数据适配类的作用主要是把图片都显示到 GridView上面，再返回此 View，然后显示到 ListView 的 item 上面。

27
28 public MyGridAdapter(List<UserImgs> ui, Context context) {
29 mLayoutInflater = LayoutInflater.from(context);
30 this.mUI = ui;
31 }
32
33 @Override
34 public int getCount() {
35 return mUI == null ? 0 : mUI.size();
36 }
37
38 @Override
39 public String getItem(int position) {
40 return mUI.get(position).urls;
41 }
42
43 @Override
44 public long getItemId(int position) {
45 return position;
46 }
47
48 @Override
49 public View getView(int position, View convertView, ViewGroup parent) {
50 MyGridViewHolder viewHolder;
51 if (convertView == null) {
52 viewHolder = new MyGridViewHolder();
53 convertView = mLayoutInflater.inflate(R.layout.user_img_item,parent, false);
54 viewHolder.imageView = (ImageView) convertView.findViewById(R.id.iv_user_img);
55 convertView.setTag(viewHolder);
56 } else {
57 viewHolder = (MyGridViewHolder) convertView.getTag();
58 }
59 String url = getItem(position);
60 imageLoader.displayImage(url, viewHolder.imageView, imageLoderHelper.getLoderOption(180, 0, 0));
61 return convertView;
62 }
63 private static class MyGridViewHolder {
64 ImageView imageView;
65 }
66 }
代码使用例子
ListView mListview = new ListView();
WeChatAdapter mWeChat = new WeChatAdapter (context);
List<UserInfo> mUserInfo = new ArrayList<>();
mUserInfo .add(你配置好的UserInfo);
mWeChat .setData(mUserInfo);
mListview .setAdapter(mWeChat );
打完收工。
