android 在 ListView 的 item 中插入 GridView 仿微信朋友圈图片显示。

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

 package cn.share.bananacloud.custom_listview_style;

 /**
  * Created by Administrator on 2015/9/6.
  */
 public class UserImgs {

     public int id; //图片的id
     public String name; //图片的名称
     public String urls; //图片的 url

     public int getId() {
         return id;
     }
     public void setId(int id) {
         this.id = id;
     }
     public String getName() {
         return name;
     }
     public void setName(String name) {
         this.name = name;
     }
     public String getUrls() {
         return urls;
     }
     public void setUrls(String urls) {
         this.urls = urls;
     }
 }

第二个，UserInfo

 package cn.share.bananacloud.custom_listview_style;

 /**
  * Created by LinGuanHong--af913337456 on 2015/9/6.
  * qq:913337456
  * email:[e-mail]
  */
 import java.util.ArrayList;
 import java.util.List;
 public class UserInfo {
     private String headUrl; // 头像 url
     private String usertext; // 帖子内容
     private String username; // 用户名称
     private String usertime; // 发帖时间
     private String usertalknumber; // 评论数目
     private List<UserImgs> ui = new ArrayList<UserImgs>(); // 这个就是我说的，UserImgs 实例
     //--------------------------------------- headUrl
     public String getHeadUrl() {
         return headUrl;
     }

     public void setHeadUrle(String headUrl) {
         this.headUrl = headUrl;
     }
     //--------------------------------------- Name
     public String getUserName() {
         return username;
     }

     public void setUserName(String username) {
         this.username = username;
     }
     //--------------------------------------- Text
     public String getUserText() {
         return usertext;
     }

     public void setUserText(String usertext) {
         this.usertext = usertext;
     }
     //---------------------------------------- Time
     public String getUserTime() {
         return usertime;
     }

     public void setUserTime(String usertime) {
         this.usertime = usertime;
     }
     //---------------------------------------- TalkNumber
     public String getUserTalkNumber() {
         return usertalknumber;
     }

     public void setUserTalkNumber(String usertalknumber) {
         this.usertalknumber = usertalknumber;
     }
     //----------------------------------------  post pics and mp3 or mp4
     public List<UserImgs> getUi() {
         return ui;
     }
     public void setUi(List<UserImgs> ui) {
         this.ui = ui;
     }
 }

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。

             if(mUserInfo.getUi().size()>0) { //这里判断该组数据是否有 gridView 的图片url数据，有才进入 gridView的配置
                 holder.gridView.setVisibility(View.VISIBLE);
                 holder.gridView.setAdapter(new MyGridAdapter(mUserInfo.getUi(), mContext));
                 // 这里我把 GridView的 item 点击监听给去掉了，防止冲突，而且我项目不需要。

                 holder.gridView.setVisibility(View.GONE);
                 holder.gridView.setAdapter(null);
             }

     public class ViewHolder {
         NoScrollGridView gridView;
         TextView username,usertext,usertime,usertalknumber;
         ImageView userHead;
     }

     public void showHeadImage(ImageView view,String url){
         //Log.d("zzzzz",""+useraccount.get((int)data));
         if (url!=null) {
             if (InternetHelper.checkConnection(mContext)) {
                 try {
                     imageLoader.displayImage(
                             url,
                             view,
                             imageLoderHelper.getLoderOption(145, R.drawable.user_default_head, 80),
                             new ImageLoadingListener() {
                                 @Override
                                 public void onLoadingStarted(String s, View view) {

                                 }

                                 @Override
                                 public void onLoadingFailed(String s, View view, FailReason failReason) {

                                 }

                                 @Override
                                 public void onLoadingComplete(String s, View view, Bitmap bitmap) {
                                     if(s.contains(InternetHelper.exchangeUserAccount(sp.getOneInfo("useraccount", "-1")))) {
                                         imageLoader.getDiskCache().remove(s);//clear old cache
                                     }
                                 }

                                 @Override
                                 public void onLoadingCancelled(String s, View view) {

                                 }
                             }
                     );
                 } catch (Exception ignored){}
             } else {
                 // load but doesn't remove local cache
                 imageLoader.displayImage
                         (
                                 commonDataHelper.rootUrl+"uploadpic/" + InternetHelper.exchangeUserAccount(url).trim() + "/head.jpg",
                                 view,
                                 imageLoderHelper.getLoderOption(145, R.drawable.user_default_head, 80)
                         );
             }
         } else {
             Log.d("zzzzz", "useraccount.size() is 0");
         }
     }
 }

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。

 package cn.share.bananacloud.custom_listview_style;

 /**
  * Created by Administrator on 2015/9/6.
  */

 import android.content.Context;
 import android.view.LayoutInflater;
 import android.view.View;
 import android.view.ViewGroup;
 import android.widget.BaseAdapter;
 import android.widget.ImageView;

 import com.nostra13.universalimageloader.core.ImageLoader;

 import java.util.List;

 import cn.share.bananacloud.R;
 import cn.share.bananacloud.imageLoderHelper;

 public class MyGridAdapter extends BaseAdapter {

     private List<UserImgs> mUI;
     protected ImageLoader imageLoader = ImageLoader.getInstance();
     private LayoutInflater mLayoutInflater;

     public MyGridAdapter(List<UserImgs> ui, Context context) {
         mLayoutInflater = LayoutInflater.from(context);
         this.mUI = ui;
     }

     @Override
     public int getCount() {
         return mUI == null ? 0 : mUI.size();
     }

     @Override
     public String getItem(int position) {
         return mUI.get(position).urls;
     }

     @Override
     public long getItemId(int position) {
         return position;
     }

     @Override
     public View getView(int position, View convertView, ViewGroup parent) {
         MyGridViewHolder viewHolder;
         if (convertView == null) {
             viewHolder = new MyGridViewHolder();
             convertView = mLayoutInflater.inflate(R.layout.user_img_item,parent, false);
             viewHolder.imageView = (ImageView) convertView.findViewById(R.id.iv_user_img);
             convertView.setTag(viewHolder);
         } else {
             viewHolder = (MyGridViewHolder) convertView.getTag();
         }
         String url = getItem(position);
         imageLoader.displayImage(url, viewHolder.imageView, imageLoderHelper.getLoderOption(180, 0, 0));
         return convertView;
     }
     private static class MyGridViewHolder {
         ImageView imageView;
     }
 }

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。
