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"/><ListViewandroid:id="@+id/lv"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_below="@+id/title"android:layout_above="@+id/ll"/>
<LinearLayoutandroid:id="@+id/ll"android:layout_width="match_parent"android:layout_height="wrap_content"android:background="#1591C9"android:orientation="horizontal"android:layout_alignParentBottom="true"><EditTextandroid:id="@+id/etMsg"android:layout_width="0dp"android:layout_height="wrap_content"android:background="#fff"android:layout_weight="3"/><Buttonandroid: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"><ImageViewandroid:id="@+id/ivRobot"android:layout_width="80dp"android:layout_height="60dp"android:src="@drawable/robot"/>
<TextViewandroid: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"/>
<TextViewandroid: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viewif (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>
