使用图灵机器人api接口开发智能聊天机器人

聊天界面

图灵机器人是一个智能机器人的开放平台，它提供了自动解析文字的API接口。创建一个机器人，就可以得到一个Key值，作为访问API的身份标识，下图的apikey就是图灵机器人对应的key值

注册完成后开始搭建项目

首先打开网络权限

只需在清单文件（AndroidManifest.xml)中添加允许访问网络权限
< uses-permission android:name=“android.permission.INTERNET”/>

界面布局

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

<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=".MainActivity">
<TextView
android:id="@+id/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="与机器人聊天"
android:gravity="center"
android:textSize="36sp"
android:background="#2894EB"/>
 <ListView
    android:id="@+id/lv"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/title"
    android:layout_above="@+id/ll"/>
<LinearLayout
    android:id="@+id/ll"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#1591C9"
    android:orientation="horizontal"
    android:layout_alignParentBottom="true"
   >
    <EditText
        android:id="@+id/etMsg"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="#fff"
        android:layout_weight="3"
        />
    <Button
        android:id="@+id/send"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="发送" />
</LinearLayout>
</RelativeLayout>

需要两个Item布局，分别显示机器人两天界面和用户聊天界面

机器人item

<?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">

<ImageView
    android:id="@+id/ivRobot"
    android:layout_width="80dp"
    android:layout_height="60dp"
    android:src="@drawable/robot"/>
<TextView
    android:id="@+id/tvMsg"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="25sp"
    android:layout_toRightOf="@+id/ivRobot"/>
</RelativeLayout>

## 用户item

<?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">
<ImageView
android:id="@+id/ivUser"
android:layout_width="80dp"
android:layout_height="60dp"
android:src="@drawable/man"
android:layout_alignParentRight="true"/>
<TextView
    android:id="@+id/tvMsg"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="25sp"
    android:layout_toLeftOf="@+id/ivUser"
    />
	</RelativeLayout>

封装聊天信息类

package com.fangkuai.chatrobot;

public class ChatBean {     
public static final int SEND = 1;           //发送消息
public static final int RECEIVE = 2;        // 接收消息 
private int state;                         //消息状态（接受或发送）
private String message;                    //发送的消息

public int getState() {
    return state;
}

public void setState(int state) {
    this.state = state;
}

public String getMessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;
}

}

编写适配器ChatAdapter

package com.fangkuai.chatrobot;

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

import java.util.List;

public class ChatAdapter extends BaseAdapter {
private List list;
private LayoutInflater inflater;

public ChatAdapter(Context context, List<ChatBean> list) {
    this.list = list;
    this.inflater = LayoutInflater.from(context);
}

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

@Override
public Object getItem(int position) {
    return list.get(position);
}

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder=new ViewHolder();
    //根据消息的状态加载不同view
    if (list.get(position).getState()==ChatBean.RECEIVE){
    //机器人布局
        convertView=inflater.inflate(R.layout.chatting_left_item,null);
    }else {
    //用户布局
        convertView=inflater.inflate(R.layout.chatting_right_item,null);
    }
    holder.message=convertView.findViewById(R.id.tvMsg);
    holder.message.setText(list.get(position).getMessage());
    return convertView;

}
class ViewHolder{
    TextView message;				//聊天内容
}
}

向服务器请求数据需要用到okhttp库的OkHttpClient类，添加okhttp库：com.squareup.okhttp3:okhttp:4.8.0

在res/values的strings.xml文件中存放欢迎信息

<resources>
 <string name="app_name">ChatRobot</string>
	<string-array name="welcome">
    <item>亲爱的，想死我了，么么哒~</item>
    <item>"更多资源，访问：http：myapptg.com</item>
    <item>主人，人家好无聊呀，来陪我耍吧</item>
    <item>"更多资源，请访问http：myapptg.com</item>
    <item>主人，自从使用了高考助手，成绩是不是提高了呢？</item>
    <item>小主人，你是不是学习累了，您可以输入，来个笑话，我可以为			您讲笑话哦</item>
    <item>主人，你是不是上班疲惫了？您可以输入，讲故事，我可以为您讲一些有趣的故事哟</item>
    <item>今天，我好累，不想和你聊天</item>
    <item>小主人您复习的怎么样了？</item>
</string-array>
</resources>
