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:text="2015/5/6 12:10:13" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<LinearLayout

android:id="@+id/chat_left_message"
android:layout_width="220dp"
android:layout_height="wrap_content"
android:text="您好。" />
</LinearLayout>
</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" >
<TextView
android:id="@+id/chat_right_time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:background="#f5f5f5"
android:paddingTop="5dp"
android:text="2015/5/6 12:10:13"
android:textSize="14sp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:orientation="horizontal" >
<TextView
android:id="@+id/chat_right_message"
android:layout_width="220dp"
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>
</LinearLayout>
</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" >
<!-- 头部 -->
<RelativeLayout
android:id="@+id/chat_top"
android:layout_width="match_parent"
android:layout_height="50dp"
android:background="#3A4449" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="小蜜"
android:textColor="#ffffff"
android:textSize="18sp" />
</RelativeLayout>
<!-- 底部 -->
<RelativeLayout
android:id="@+id/chat_bottom"
android:layout_width="match_parent"
android:layout_height="55dp"
android:layout_alignParentBottom="true"
android:background="#3A4449" >
<EditText
android:id="@+id/chat_input_message"
android:layout_width="240dp"
android:background="@drawable/shuruborder"
android:layout_height="wrap_content"
android:layout_centerVertical="true"

android:layout_height="match_parent"
android:layout_above="@id/chat_bottom"
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" /> <!-- 网络权限 -->
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"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke
android:width="1dp"
android:color="#FFF" />
<solid android:color="#FFF" />
<corners android:radius="5dip" />
</shape>
②.小星聊天框的样式(kefuborder)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke
android:width="1dp"
android:color="#5188DE" />
<solid android:color="#A5D932" />
<corners android:radius="8dip" />
</shape>
③.自己聊天框的样式(myborder)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke
android:width="1dp"
android:color="#787878" />
<solid android:color="#FFFFFF" />
<corners android:radius="8dip" />
</shape>
④.发送按钮的样式(btnborder)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#CCCCCC"/>
<corners android:radius="5dip"/>
</shape>
二、效果图
