    先上图:


    说下大致实现的步骤:
    1、首先使用了聚合数据的sdk,这样免费使用的数目可以多一些
    2、使用gson来解析json数据
    3、使用ListView来显示数据

    那,先将布局贴上来
    数据部分 机器人和人布局类似 只粘一个

    <?xml version="1.0" encoding="utf-8"?>    
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    
        android:layout_width="match_parent"    
        android:layout_height="match_parent"    
        android:orientation="vertical" >    
        
        <TextView    
            android:id="@+id/robot_time"    
            android:layout_width="wrap_content"    
            android:layout_height="wrap_content"    
            android:layout_gravity="center"    
            android:textColor="#cccccc"    
            android:gravity="center_horizontal"    
            android:text="2015-8-23 17:37:23" />    
        
        <LinearLayout    
            android:layout_width="wrap_content"    
            android:layout_height="wrap_content"    
            android:orientation="horizontal" >    
        
            <LinearLayout    
                android:layout_width="wrap_content"    
                android:layout_height="wrap_content"    
                android:orientation="vertical" >    
        
                <ImageView    
                    android:layout_width="50dp"    
                    android:layout_height="50dp"    
                    android:src="@drawable/icon" />    
        
                <TextView    
                    android:layout_width="wrap_content"    
                    android:layout_height="wrap_content"    
                    android:layout_gravity="center"    
                    android:gravity="center_horizontal"    
                    android:text="小桂子"    
                    android:textSize="12sp" />    
            </LinearLayout>    
        
            <TextView    
                android:id="@+id/robot_msg"    
                android:layout_width="wrap_content"    
                android:layout_height="wrap_content"    
                android:layout_marginLeft="5dp"    
                android:background="@drawable/chatfrom_bg_normal"    
                android:gravity="center"    
                android:layout_gravity="bottom"    
                android:text="你好,我是小桂子" />    
        </LinearLayout>    
        
    </LinearLayout>    
    

    然后是主布局:

    <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"    
        tools:context="com.example.juheapi.MainActivity" >    
        
        <RelativeLayout    
            android:id="@+id/titleBar"    
            android:layout_width="fill_parent"    
            android:layout_height="50dp"    
            android:layout_alignParentTop="true"    
            android:background="@drawable/title_bar" >    
        
            <TextView    
                android:layout_width="wrap_content"    
                android:layout_height="wrap_content"    
                android:layout_centerInParent="true"    
                android:text="小桂子 贱贱哒"    
                android:textColor="#eeeeee"    
                android:textStyle="bold" />    
        </RelativeLayout>    
        
        <ListView    
            android:id="@+id/listView"    
            android:layout_width="fill_parent"    
            android:layout_height="fill_parent"    
            android:layout_above="@+id/buttom"    
            android:layout_below="@+id/titleBar"    
            android:divider="@null"    
            android:dividerHeight="5dp"    
            android:fastScrollEnabled="true"    
            android:scrollbarStyle="insideInset"    
            android:transcriptMode="normal" >    
        </ListView>    
        
        <RelativeLayout    
            android:id="@+id/buttom"    
            android:layout_width="fill_parent"    
            android:layout_height="50dp"    
            android:layout_alignParentBottom="true"    
            android:background="@drawable/bottom_bar" >    
        
            <Button    
                android:id="@+id/send_but"    
                android:layout_width="wrap_content"    
                android:layout_height="40dp"    
                android:layout_alignParentRight="true"    
                android:layout_centerInParent="true"    
                android:layout_marginLeft="5dp"    
                android:layout_marginRight="5dp"    
                android:background="@drawable/but_send_bg"    
                android:text="发 送" />    
        
            <EditText    
                android:id="@+id/send_msg"    
                android:layout_width="fill_parent"    
                android:layout_height="40dp"    
                android:layout_centerInParent="true"    
                android:layout_marginLeft="5dp"    
                android:layout_toLeftOf="@+id/send_but"    
                android:background="@drawable/login_edit_normal"    
                android:hint="你想说点什么?"    
                android:typeface="monospace" />    
        </RelativeLayout>    
        
    </RelativeLayout>    
    

    发送按钮的xml文件:

    <?xml version="1.0" encoding="utf-8"?>    
    <selector xmlns:android="http://schemas.android.com/apk/res/android">    
        
        <item android:drawable="@drawable/send_btn_pressed" android:state_pressed="true"></item>    
        <item android:drawable="@drawable/send_btn_normal"></item>    
        
    </selector>    
    

    这样布局 就算搭建好了
    先说说 聚合数据 SDK的使用吧 地址:https://www.juhe.cn/juhesdk
    下载完之后 需要导入jar包 新建application初始化sdk 以及manifest的配置, 里面有详细教程
    需要注意的的是 ip 的值 并不像教程上说的那样 而是需要加上完整的 URL 、info 和 KEY

    Parameters params = new Parameters();    
            params.add("ip", URL + msg + KEY);    
            params.add("dtype", "json");    
    

    下面是访问数据和解析数据的实现
    需要用到gson

    package com.util;    
        
    import java.util.Date;    
        
    import android.content.Context;    
    import android.os.Handler;    
    import android.os.Message;    
        
    import com.bean.GetResult;    
    import com.bean.SetChatMessage;    
    import com.bean.SetChatMessage.Type;    
    import com.google.gson.Gson;    
    import com.thinkland.sdk.android.DataCallBack;    
    import com.thinkland.sdk.android.JuheData;    
    import com.thinkland.sdk.android.Parameters;    
        
    public class RequestHttp {    
        private static final String URL = "http://op.juhe.cn/robot/index?info=";    
        private static final String KEY = "&key=5d0a9e4aad4c9b11f53cc**********";    
        private Context context;    
        private Handler handle;    
        
        public RequestHttp(Context context, Handler handle) {    
            this.context = context;    
            this.handle = handle;    
        }    
        
        public  void requestHttp(String msg) {    
            Parameters params = new Parameters();    
            params.add("ip", URL + msg + KEY);    
            params.add("dtype", "json");    
        
            JuheData.executeWithAPI(context, 112, URL + msg + KEY, JuheData.GET,    
                    params, new DataCallBack() {     
        
                        public void onSuccess(int statusCode, String responseString) {    
                            // TODO Auto-generated method stub    
                            SetChatMessage chat = new SetChatMessage();    
                            Gson gson = new Gson();    
                            GetResult value = gson.fromJson(responseString,    
                                    GetResult.class);    
                            chat.setMsg(value.getResult().getText());    
                            chat.setDate(new Date());    
                            chat.setType(Type.INCOME);    
                            Message mesg = Message.obtain(handle);    
                            mesg.obj = chat;    
                            mesg.sendToTarget();    
                        }    
        
                        public void onFinish() {    
                        }    
        
                        public void onFailure(int statusCode,    
                                String responseString, Throwable throwable) {    
                            SetChatMessage chat = new SetChatMessage();    
                            chat.setMsg("服务器忙,请稍候。。。");    
                            chat.setDate(new Date());    
                            chat.setType(Type.INCOME);    
                            Message mesg = Message.obtain(handle);    
                            mesg.obj = chat;    
                            mesg.sendToTarget();    
                        }    
        
                    });    
        
        }    
    }    
    

    上面的gson解析 需要JSON数据映射成一个对象

    package com.bean;    
        
    public class GetResult {    
        private Result result;    
        
        public Result getResult() {    
            return result;    
        }    
        
        public void setResult(Result result) {    
            this.result = result;    
        }    
        
        public class Result {    
            private int code;    
            private String text;    
        
            public int getCode() {    
                return code;    
            }    
        
            public void setCode(int code) {    
                this.code = code;    
            }    
        
            public String getText() {    
                return text;    
            }    
        
            public void setText(String text) {    
                this.text = text;    
            }    
        }    
    }    
    

    上面是两个类嵌套的 因为数据格式是:{ x, y{z,u}}
    需要拿到z的值,就必须这样做,注意“text”和“code”的是和数据z、u对应的 不能随意设定

    还需要对数据进行封装:

    package com.bean;    
        
    import java.util.Date;    
        
    public class SetChatMessage {    
        private String name;    
        private String msg;    
        private Date date;    
        private Type type;    
            
        public enum Type{    
            INCOME,OUTCOME    
        }    
            
        public SetChatMessage(){}    
            
        public SetChatMessage(String msg,Date date,Type type){    
            this.msg=msg;    
            this.date=date;    
            this.type=type;    
        }    
        
            
        public String getName() {    
            return name;    
        }    
        
        public void setName(String name) {    
            this.name = name;    
        }    
        
        public String getMsg() {    
            return msg;    
        }    
        
        public void setMsg(String msg) {    
            this.msg = msg;    
        }    
        
        public Date getDate() {    
            return date;    
        }    
        
        public void setDate(Date date) {    
            this.date = date;    
        }    
        
        public Type getType() {    
            return type;    
        }    
        
        public void setType(Type type) {    
            this.type = type;    
        }    
            
            
    }    
    

    还需要给Listview写个适配器:

    package com.example.juheapi;    
        
    import java.text.SimpleDateFormat;    
    import java.util.List;    
    import java.util.Locale;    
        
    import com.bean.SetChatMessage;    
    import com.bean.SetChatMessage.Type;    
    import com.example.juheapi.R.id;    
        
    import android.content.Context;    
    import android.view.LayoutInflater;    
    import android.view.View;    
    import android.view.ViewGroup;    
    import android.widget.BaseAdapter;    
    import android.widget.TextView;    
        
    public class MyAdapter extends BaseAdapter {    
        private List<SetChatMessage> dataList;    
        private LayoutInflater mInflater;    
        
        public MyAdapter(Context context, List<SetChatMessage> dataList) {    
            this.dataList = dataList;    
            mInflater = LayoutInflater.from(context);    
        }    
        
        public int getCount() {    
            return dataList.size();    
        }    
        
        public Object getItem(int position) {    
            return dataList.get(position);    
        }    
        
        public long getItemId(int position) {    
            return position;    
        }    
        
        public int getItemViewType(int position) {    
            SetChatMessage chatMsg = dataList.get(position);    
            if (chatMsg.getType() == Type.INCOME) {    
                return 0;    
            }    
            return 1;    
        }    
        
        public int getViewTypeCount() {    
            return 2;    
        }    
        
        public View getView(int position, View convertView, ViewGroup parent) {    
            SetChatMessage chatMsg = dataList.get(position);    
            ViewHolder viewHolder;    
            if (convertView == null) {    
                if (getItemViewType(position) == 0) {    
                    convertView = mInflater.inflate(R.layout.item_robot_msg,    
                            parent, false);    
                    viewHolder = new ViewHolder();    
                    viewHolder.msgData = (TextView) convertView    
                            .findViewById(id.robot_msg);    
                    viewHolder.timeData = (TextView) convertView    
                            .findViewById(id.robot_time);    
                } else {    
                    convertView = mInflater.inflate(R.layout.item_host_msg, parent,    
                            false);    
                    viewHolder = new ViewHolder();    
                    viewHolder.msgData = (TextView) convertView    
                            .findViewById(id.host_msg);    
                    viewHolder.timeData = (TextView) convertView    
                            .findViewById(id.host_time);    
                }    
                convertView.setTag(viewHolder);    
            } else {    
                    
                viewHolder = (ViewHolder) convertView.getTag();    
                    
            }    
            viewHolder.msgData.setText(chatMsg.getMsg());    
            SimpleDateFormat dateFormat=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss",Locale.CHINA);    
            viewHolder.timeData.setText(dateFormat.format(chatMsg.getDate()));    
                
            return convertView;    
        }    
        
        private class ViewHolder {    
            private TextView timeData;    
            private TextView msgData;    
        }    
        
    }    
    

    说一下适配器:
     1、因为有两种不同的view 所以需要复写 getItemViewType(int position) 和 getViewTypeCount();
     2、使用ViewHolder 对性能进行优化,减少一些不必要的重复操作

            }

                        Toast.makeText(MainActivity.this, "消息不能为空。",

            send_msg = (EditText) findViewById(id.send_msg);    
        
        }    
        
    }    
    

    总结一下实现过程:
      List数据----adapter处理------ListView显示
    1、首先是数据的获得 ,通过对 免费提供的数据接口进行访问 拿到数据
      由于是网络访问 并不能立刻拿到数据 通过return是不能将响应的数据立刻返回的,所以使用了message来专递数据,handler进行处理
    2、数据是json格式的,通过对数据进行分析 使用gson解析数据 并拿到自己需要的数据
    3、对数据进行封装 ,添加数据的类型 时间等
     
    4、数据解决了就需要adapter来处理数据 继承自baseAdapter 使用viewHolder 来提高效率
    5、listview的显示 布局的搭建 以及对显示的需求 
      设置无分隔线 以及分隔高度
        android:divider="@null" android:dividerHeight="5dp" 
      设置数据向上滚动 以免输入法挡住数据
       android:fastScrollEnabled="true" android:scrollbarStyle="insideInset" android:transcriptMode="normal"
      等等。。。按自己喜好更改
