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🇲🇲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

 

main:

    private Handler handle = new Handler() {    
        public void handleMessage(Message msg) {    
            SetChatMessage chatMsg = (SetChatMessage) msg.obj;    
            dataList.add(chatMsg);    
            myAdapter.notifyDataSetChanged();    
        }    
    };    
    
    protected void onCreate(Bundle savedInstanceState) {    
        super.onCreate(savedInstanceState);    
        requestWindowFeature(Window.FEATURE_NO_TITLE);

                if (TextUtils.isEmpty(msg)) {    
                    Toast.makeText(MainActivity.this, "消息不能为空。",    
                            Toast.LENGTH_SHORT).show();    
                    return;    
                }    
    
                // 设置消息源 显示到listview中    
                SetChatMessage chatMsg = new SetChatMessage();    
                chatMsg.setDate(new Date());    
                chatMsg.setMsg(msg);    
                chatMsg.setType(Type.OUTCOME);    
                dataList.add(chatMsg);    
                myAdapter.notifyDataSetChanged();    
                // 文本框清空    
                send_msg.setText("");    
                // 将消息发送至服务端    
                RequestHttp an = new RequestHttp(getApplicationContext(),    
                        handle);    
                an.requestHttp(msg);    
            }    
        });    
    
    }    
    
    private void initData() {    
        dataList.add(new SetChatMessage("你要和小桂子吐槽点什么啊?", new Date(),    
                Type.INCOME));    
    
        myAdapter = new MyAdapter(MainActivity.this, dataList);    
        listView.setAdapter(myAdapter);    
    }    
    
    private void initView() {    
        listView = (ListView) findViewById(id.listView);    
    
        send_but = (Button) findViewById(id.send_but);    
        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
