ndroid实现智能问答机器人（二） -----基于图灵机器人实现对话

一、具体实现的代码

1、配置类,配置自己的图灵机器人(Config)（后期改成我们的后台为服务器的连接）

public class Config {

public static final String URL_KEY = "http://www.tuling123.com/openapi/api";

public static final String APP_KEY = "38026ee35d614607b29c4ef3a56474a7";//此处是申请的Apikey

}

2.格式化日期时间的工具类,用于显示时间(DateUtils)

import android.annotation.SuppressLint;

import java.text.SimpleDateFormat;

import java.util.Date;

/**

* 时间格式化工具类

public class DateUtils {

@SuppressLint("SimpleDateFormat")

public static String dateToString(Date date) {

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

return df.format(date);

}

3.HttpUtils网络请求类(HttpUtils)

import com.google.gson.Gson;

import java.io.ByteArrayOutputStream;

import java.io.IOException;

import java.io.InputStream;

import java.io.UnsupportedEncodingException;

import java.net.HttpURLConnection;

import java.net.URL;

import java.net.URLEncoder;

import java.util.Date;

/**

* author:Created by ZhangPengFei.

* data: 2017/12/28

* http工具类

public class HttpUtils {

/**

* 发送消息到服务器

* @return：消息对象

public static ChatMessage sendMessage(String message) {

ChatMessage chatMessage = new ChatMessage();

String gsonResult = doGet(message);

Gson gson = new Gson();

Result result = null;

if (gsonResult != null) {

try {

result = gson.fromJson(gsonResult, Result.class);

chatMessage.setMessage(result.getText());

} catch (Exception e) {

chatMessage.setMessage("服务器繁忙，请稍候再试...");

}

chatMessage.setData(new Date());

chatMessage.setType(ChatMessage.Type.INCOUNT);

return chatMessage;

}

/**

* get请求

* @param message ：发送的话

* @return：数据

public static String doGet(String message) {

String result = "";

String url = setParmat(message);

System.out.println("------------url = " + url);

InputStream is = null;

ByteArrayOutputStream baos = null;

try {

URL urls = new URL(url);

HttpURLConnection connection = (HttpURLConnection) urls

.openConnection();

connection.setReadTimeout(5 * 1000);

connection.setConnectTimeout(5 * 1000);

connection.setRequestMethod("GET");

is = connection.getInputStream();

baos = new ByteArrayOutputStream();

int len = -1;

byte[] buff = new byte[1024];

while ((len = is.read(buff)) != -1) {

baos.write(buff, 0, len);

}

baos.flush();

result = new String(baos.toByteArray());

} catch (Exception e) {

e.printStackTrace();

} finally {

if (is != null) {

try {

is.close();

} catch (IOException e) {

e.printStackTrace();

}

if (baos != null) {

try {

baos.close();

} catch (IOException e) {

e.printStackTrace();

}

return result;

}

/**

* 设置参数

* @param message : 信息

* @return ： url

private static String setParmat(String message) {

String url = "";

try {

url = Config.URL_KEY + "?" + "key=" + Config.APP_KEY + "&info="

+ URLEncoder.encode(message, "UTF-8");

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

}

return url;

}

4.请求api地址返回的数据(Result)

/**

* 映射服务器返回的结果

public class Result {

private int code; // code码

private String text; // 信息

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;

}

10.聊天消息的实体类(ChatMessage)

import java.util.Date;

/**

* 聊天消息的实体类

public class ChatMessage {

private String name;// 姓名

private String message;// 消息

private Type type;// 类型：0.发送者 1.接受者

private Date data;// 时间

public ChatMessage() {

}

public ChatMessage(String message, Type type, Date data) {

super();

this.message = message;

this.type = type;

this.data = data;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getMessage() {

return message;

}

public void setMessage(String message) {

this.message = message;

}

public Type getType() {

return type;

}

public void setType(Type type) {

this.type = type;

}

public Date getData() {

return data;

}

public void setData(Date data) {

this.data = data;

}

public enum Type {

INCOUNT, OUTCOUNT

}

5.服务器发送与接收消息,左边布局的实现(layout_left)

<?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:background="#f5f5f5"

android:id="@+id/chat_left_time"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="center"

android:paddingTop="5dp"

android:textSize="14sp"

android:layout_width="220dp"

android:layout_height="wrap_content"

android:text="您好。" />

</LinearLayout>

6.客户端发送与接收消息,右边布局的实现(layout_right)

<?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" >

android:layout_height="wrap_content"

android:layout_gravity="center_vertical"

android:layout_marginRight="10dp"

android:background="@drawable/myborder"

android:gravity="center"

android:text="can i help me ?"

android:textSize="16sp" />

<LinearLayout

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:orientation="vertical" >

<ImageView

android:id="@+id/chat_right_image"

android:layout_width="100dp"

android:layout_height="100dp"

android:src="@drawable/m" />

<TextView

android:id="@+id/chat_right_name"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginLeft="25dp"

android:layout_marginTop="5dp"

android:text="zengtao"

android:textSize="16sp" />

</LinearLayout>

7.主界面聊天页面布局的实现(activity_chat)

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:background="@drawable/bac"

android:orientation="vertical" >

<RelativeLayout

android:id="@+id/chat_top"

android:layout_width="match_parent"

android:layout_below="@id/chat_top"

android:divider="@null"

android:dividerHeight="3dp" >

</ListView>

</RelativeLayout>

8.聊天消息的适配器(ChatMessageAdapter)

/**

* author:Created by ZhangPengFei.

* data: 2017/12/28

import android.annotation.SuppressLint;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.TextView;

import java.util.List;

import weektest.project.R;

/**

* 聊天信息适配器

public class ChatMessageAdapter extends BaseAdapter {

private List<ChatMessage> list;

public ChatMessageAdapter(List<ChatMessage> list) {

this.list = list;

}

@Override

public int getCount() {

return list.isEmpty() ? 0 : list.size();

}

@Override

public Object getItem(int position) {

return list.get(position);

}

@Override

public long getItemId(int position) {

return position;

}

@Override

public int getItemViewType(int position) {

ChatMessage chatMessage = list.get(position);

// 如果是接收消息：0，发送消息：1

if (chatMessage.getType() == ChatMessage.Type.INCOUNT) {

return 0;

}

return 1;

}

@Override

public int getViewTypeCount() {

return 2;

}

@SuppressLint("InflateParams")

@Override

public View getView(int position, View convertView, ViewGroup parent) {

ChatMessage chatMessage = list.get(position);

if (convertView == null) {

ViewHolder viewHolder = null;

// 通过ItemType加载不同的布局

if (getItemViewType(position) == 0) {

convertView = LayoutInflater.from(parent.getContext()).inflate(

R.layout.layout_left, null);

viewHolder = new ViewHolder();

viewHolder.chat_time = (TextView) convertView

.findViewById(R.id.chat_left_time);

viewHolder.chat_message = (TextView) convertView

.findViewById(R.id.chat_left_message);

} else {

convertView = LayoutInflater.from(parent.getContext()).inflate(

R.layout.layout_right, null);

viewHolder = new ViewHolder();

viewHolder.chat_time = (TextView) convertView

.findViewById(R.id.chat_right_time);

viewHolder.chat_message = (TextView) convertView

.findViewById(R.id.chat_right_message);

}

convertView.setTag(viewHolder);

}

// 设置数据

ViewHolder vh = (ViewHolder) convertView.getTag();

vh.chat_time.setText(DateUtils.dateToString(chatMessage.getData()));

vh.chat_message.setText(chatMessage.getMessage());

return convertView;

}

/**

* 内部类：只寻找一次控件

* @author zengtao 2015年5月6日下午2:27:57

private class ViewHolder {

private TextView chat_time, chat_message;

}

9.主java的实现(ChatActivity)

import android.annotation.SuppressLint;

import android.app.Activity;

import android.os.Bundle;

import android.os.Handler;

import android.os.Message;

import android.text.TextUtils;

import android.view.View;

import android.view.View.OnClickListener;

import android.view.Window;

import android.widget.Button;

import android.widget.EditText;

import android.widget.ListView;

import android.widget.Toast;

import java.util.ArrayList;

import java.util.Date;

import java.util.List;

import weektest.project.R;

public class ChatActivity extends Activity {

private List<ChatMessage> list;

private ListView chat_listview;

private EditText chat_input;

private Button chat_send;

private ChatMessageAdapter chatAdapter;

private ChatMessage chatMessage = null;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

requestWindowFeature(Window.FEATURE_NO_TITLE);

setContentView(R.layout.activity_chat);

initView();

initListener();

initData();

}

// 1.初始试图

private void initView() {

// 1.初始化

chat_listview = (ListView) findViewById(R.id.chat_listview);

chat_input = (EditText) findViewById(R.id.chat_input_message);

chat_send = (Button) findViewById(R.id.chat_send);

}

// 2.设置监听事件

private void initListener() {

chat_send.setOnClickListener(onClickListener);

}

// 3.初始化数据

private void initData() {

list = new ArrayList<ChatMessage>();

list.add(new ChatMessage("您好,小乖为您服务!", ChatMessage.Type.INCOUNT, new Date()));

chatAdapter = new ChatMessageAdapter(list);

chat_listview.setAdapter(chatAdapter);

chatAdapter.notifyDataSetChanged();

}

// 4.发送消息聊天

private void chat() {

// 1.判断是否输入内容

final String send_message = chat_input.getText().toString().trim();

if (TextUtils.isEmpty(send_message)) {

Toast.makeText(ChatActivity.this, "对不起，您还未发送任何消息",

Toast.LENGTH_SHORT).show();

return;

}

// 2.自己输入的内容也是一条记录，记录刷新

ChatMessage sendChatMessage = new ChatMessage();

sendChatMessage.setMessage(send_message);

sendChatMessage.setData(new Date());

sendChatMessage.setType(ChatMessage.Type.OUTCOUNT);

list.add(sendChatMessage);

chatAdapter.notifyDataSetChanged();

chat_input.setText("");

// 3.发送你的消息，去服务器端，返回数据

new Thread() {

public void run() {

ChatMessage chat = HttpUtils.sendMessage(send_message);

Message message = new Message();

message.what = 0x1;

message.obj = chat;

handler.sendMessage(message);

};

}.start();

}

@SuppressLint("HandlerLeak")

private Handler handler = new Handler() {

public void handleMessage(android.os.Message msg) {

if (msg.what == 0x1) {

if (msg.obj != null) {

chatMessage = (ChatMessage) msg.obj;

}

// 添加数据到list中，更新数据

list.add(chatMessage);

chatAdapter.notifyDataSetChanged();

}

};

// 点击事件监听

OnClickListener onClickListener = new OnClickListener() {

@Override

public void onClick(View v) {

switch (v.getId()) {

case R.id.chat_send:

chat();

break;

}

};

}

10.权限与依赖问题

<uses-permission android:name="android.permission.INTERNET" />

compile 'com.google.code.gson:gson:2.2.4'//Gson解析依赖

18.写了这么多,就把图片和绘制的形状一块给你们吧,

①.输入框的样式(shuruborder)

<?xml version="1.0" encoding="utf-8"?>

<stroke

android:width="1dp"

android:color="#FFF" />

</shape>

②.小星聊天框的样式(kefuborder)

<?xml version="1.0" encoding="utf-8"?>

<stroke

android:width="1dp"

android:color="#5188DE" />

</shape>

③.自己聊天框的样式(myborder)

<?xml version="1.0" encoding="utf-8"?>

<stroke

android:width="1dp"

android:color="#787878" />

</shape>

④.发送按钮的样式(btnborder)

<?xml version="1.0" encoding="utf-8"?>

</shape>

二、效果图
