今天看到一个ios写的图灵机器人，直接去官网（http://www.tuling123.com/openapi/）看了下API接入，太简单了，就一个get请求~于是乎。写了一个Android版本号的机器人，没什么技术含量，可是挺好玩的~刚好昨晚看了自己喜欢的秦时明月。嘿嘿，小貔貅，就是我的机器人宠物啦~

1、效果图

先看看效果图：

当然不仅是闲聊，还有更强大的。见下图：

好了，效果图就先这样了，有兴趣的自己去研究下。还支持自己主动学习噢 ~

以下開始代码了~

2、布局文件

主界面消息的显示是一个ListView，只是这个listView中的Item有两种风格。一个是左边的绿色消息，一个是右边的白色消息

左边的消息布局文件：

<?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="wrap_content" android:orientation="vertical" > <TextView android:id="@+id/chat_from_createDate" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="2012-09-01 18:30:20" style="@style/chat_date_style" /> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" > <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:orientation="vertical" > <ImageView android:id="@+id/chat_from_icon" android:layout_width="49dp" android:layout_height="49dp" android:src="@drawable/icon" /> <TextView android:id="@+id/chat_from_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:text="小貅貅" android:textSize="18sp" /> </LinearLayout> <TextView android:id="@+id/chat_from_content" android:layout_width="wrap_content" android:layout_height="wrap_content" android:minHeight="50dp" android:background="@drawable/chat_from_msg" android:text="有大吗。。。

" android:textSize="18sp" android:textColor="#000" android:gravity="center_vertical" android:focusable="true" android:clickable="true" android:lineSpacingExtra="2dp" /> </LinearLayout> </LinearLayout>

右边的和左边基本一致，就不贴了。最后会给出代码。

主布局文件：

<?

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/chat_bg_default" android:orientation="vertical" > <RelativeLayout android:id="@+id/ly_chat_title" android:layout_width="fill_parent" android:layout_height="45dp" android:background="@drawable/title_bar" > <TextView android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:text="小貔貅" android:textColor="#fff" android:textSize="20sp" android:textStyle="bold" /> </RelativeLayout> <RelativeLayout android:id="@+id/ly_chat_bottom" android:layout_width="fill_parent" android:layout_height="55dp" android:layout_alignParentBottom="true" android:background="@drawable/bottom_bar" > <Button android:id="@+id/id_chat_send" android:layout_width="60dp" android:layout_height="40dp" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:layout_marginRight="10dp" android:background="@drawable/chat_send_btn" android:onClick="sendMessage" android:text="发送" /> <EditText android:id="@+id/id_chat_msg" android:layout_width="fill_parent" android:layout_height="40dp" android:layout_centerVertical="true" android:layout_marginLeft="10dp" android:layout_marginRight="10dp" android:layout_toLeftOf="@id/id_chat_send" android:background="@drawable/login_edit_normal" android:singleLine="true" android:textSize="18sp" /> </RelativeLayout> <ListView android:id="@+id/id_chat_listView" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_above="@id/ly_chat_bottom" android:layout_below="@id/ly_chat_title" android:cacheColorHint="#0000" android:divider="@null" android:dividerHeight="5dp" android:scrollbarStyle="outsideOverlay" > </ListView> </RelativeLayout>

就是ListView和以下的消息框和消息button了~没撒好说的

3、HttpUtils

封装了一个用于訪问API的工具类，事实上就一个Get请求：

package com.zhy.utils;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;import com.example.android_robot_01.bean.ChatMessage;
import com.example.android_robot_01.bean.ChatMessage.Type;
import com.example.android_robot_01.bean.CommonException;
import com.example.android_robot_01.bean.Result;
import com.google.gson.Gson;public class HttpUtils
{private static String API_KEY = "534dc342ad15885dffc10d7b5f813451";private static String URL = "http://www.tuling123.com/openapi/api";/*** 发送一个消息。并得到返回的消息* @param msg* @return*/public static ChatMessage sendMsg(String msg){ChatMessage message = new ChatMessage();String url = setParams(msg);String res = doGet(url);Gson gson = new Gson();Result result = gson.fromJson(res, Result.class);if (result.getCode() > 400000 || result.getText() == null|| result.getText().trim().equals("")){message.setMsg("该功能等待开发...");}else{message.setMsg(result.getText());}message.setType(Type.INPUT);message.setDate(new Date());return message;}/*** 拼接Url* @param msg* @return*/private static String setParams(String msg){try{msg = URLEncoder.encode(msg, "UTF-8");} catch (UnsupportedEncodingException e){e.printStackTrace();}return URL + "?key=" + API_KEY + "&info=" + msg;}/*** Get请求。获得返回数据* @param urlStr* @return*/private static String doGet(String urlStr){URL url = null;HttpURLConnection conn = null;InputStream is = null;ByteArrayOutputStream baos = null;try{url = new URL(urlStr);conn = (HttpURLConnection) url.openConnection();conn.setReadTimeout(5 * 1000);conn.setConnectTimeout(5 * 1000);conn.setRequestMethod("GET");if (conn.getResponseCode() == 200){is = conn.getInputStream();baos = new ByteArrayOutputStream();int len = -1;byte[] buf = new byte[128];while ((len = is.read(buf)) != -1){baos.write(buf, 0, len);}baos.flush();return baos.toString();} else{throw new CommonException("server连接错误！

"); } } catch (Exception e) { e.printStackTrace(); throw new CommonException("server连接错误！"); } finally { try { if (is != null) is.close(); } catch (IOException e) { e.printStackTrace(); } try { if (baos != null) baos.close(); } catch (IOException e) { e.printStackTrace(); } conn.disconnect(); } } }

暴露出去的，就是sendMsg这个静态方法。当然将返回的数据也直接封装成了ChatMessage

4、ChatMessage

package com.example.android_robot_01.bean;import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;public class ChatMessage
{/*** 消息类型*/private Type type ;/*** 消息内容*/private String msg;/*** 日期*/private Date date;/*** 日期的字符串格式*/private String dateStr;/*** 发送人*/private String name;public enum Type{INPUT, OUTPUT}public ChatMessage(){}public ChatMessage(Type type, String msg){super();this.type = type;this.msg = msg;setDate(new Date());}public String getDateStr(){return dateStr;}public Date getDate(){return date;}public void setDate(Date date){this.date = date;DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");this.dateStr = df.format(date);}public String getName(){return name;}public void setName(String name){this.name = name;}public Type getType(){return type;}public void setType(Type type){this.type = type;}public String getMsg(){return msg;}public void setMsg(String msg){this.msg = msg;}}

都没撒好说的。非常easy~

5、主Activity

package com.example.android_robot_01;import java.util.ArrayList;
import java.util.Date;
import java.util.List;import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.text.TextUtils;
import android.view.View;
import android.view.Window;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Toast;import com.example.android_robot_01.bean.ChatMessage;
import com.example.android_robot_01.bean.ChatMessage.Type;
import com.zhy.utils.HttpUtils;public class MainActivity extends Activity
{/*** 展示消息的listview*/private ListView mChatView;/*** 文本域*/private EditText mMsg;/*** 存储聊天消息*/private List<ChatMessage> mDatas = new ArrayList<ChatMessage>();/*** 适配器*/private ChatMessageAdapter mAdapter;private Handler mHandler = new Handler(){public void handleMessage(android.os.Message msg){ChatMessage from = (ChatMessage) msg.obj;mDatas.add(from);mAdapter.notifyDataSetChanged();mChatView.setSelection(mDatas.size() - 1);};};@Overrideprotected void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.main_chatting);initView();mAdapter = new ChatMessageAdapter(this, mDatas);mChatView.setAdapter(mAdapter);}private void initView(){mChatView = (ListView) findViewById(R.id.id_chat_listView);mMsg = (EditText) findViewById(R.id.id_chat_msg);mDatas.add(new ChatMessage(Type.INPUT, "我是小貅貅。非常高兴为您服务"));}public void sendMessage(View view){final String msg = mMsg.getText().toString();if (TextUtils.isEmpty(msg)){Toast.makeText(this, "您还没有填写信息呢...", Toast.LENGTH_SHORT).show();return;}ChatMessage to = new ChatMessage(Type.OUTPUT, msg);to.setDate(new Date());mDatas.add(to);mAdapter.notifyDataSetChanged();mChatView.setSelection(mDatas.size() - 1);mMsg.setText("");// 关闭软键盘InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);// 得到InputMethodManager的实例if (imm.isActive()){// 假设开启imm.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT,InputMethodManager.HIDE_NOT_ALWAYS);// 关闭软键盘。开启方法同样，这种方法是切换开启与关闭状态的}new Thread(){public void run(){ChatMessage from = null;try{from = HttpUtils.sendMsg(msg);} catch (Exception e){from = new ChatMessage(Type.INPUT, "server挂了呢...");}Message message = Message.obtain();message.obj = from;mHandler.sendMessage(message);};}.start();}}

为ListView设置数据。一開始就设置了第一句话“我是小貅貅。非常高兴为您服务”。还有就是sendButton的事件处理。

6、适配器

package com.example.android_robot_01;import java.util.List;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 com.example.android_robot_01.bean.ChatMessage;
import com.example.android_robot_01.bean.ChatMessage.Type;public class ChatMessageAdapter extends BaseAdapter
{private LayoutInflater mInflater;private List<ChatMessage> mDatas;public ChatMessageAdapter(Context context, List<ChatMessage> datas){mInflater = LayoutInflater.from(context);mDatas = datas;}@Overridepublic int getCount(){return mDatas.size();}@Overridepublic Object getItem(int position){return mDatas.get(position);}@Overridepublic long getItemId(int position){return position;}/*** 接受到消息为1，发送消息为0*/@Overridepublic int getItemViewType(int position){ChatMessage msg = mDatas.get(position);return msg.getType() == Type.INPUT ?

1 : 0; } @Override public int getViewTypeCount() { return 2; } @Override public View getView(int position, View convertView, ViewGroup parent) { ChatMessage chatMessage = mDatas.get(position); ViewHolder viewHolder = null; if (convertView == null) { viewHolder = new ViewHolder(); if (chatMessage.getType() == Type.INPUT) { convertView = mInflater.inflate(R.layout.main_chat_from_msg, parent, false); viewHolder.createDate = (TextView) convertView .findViewById(R.id.chat_from_createDate); viewHolder.content = (TextView) convertView .findViewById(R.id.chat_from_content); convertView.setTag(viewHolder); } else { convertView = mInflater.inflate(R.layout.main_chat_send_msg, null); viewHolder.createDate = (TextView) convertView .findViewById(R.id.chat_send_createDate); viewHolder.content = (TextView) convertView .findViewById(R.id.chat_send_content); convertView.setTag(viewHolder); } } else { viewHolder = (ViewHolder) convertView.getTag(); } viewHolder.content.setText(chatMessage.getMsg()); viewHolder.createDate.setText(chatMessage.getDateStr()); return convertView; } private class ViewHolder { public TextView createDate; public TextView name; public TextView content; } }

唯一须要注意的是，由于我们的ListView的Item有两种显示风格，所以比平时我们须要多重写两个方法：

/*** 接受到消息为1。发送消息为0*/@Overridepublic int getItemViewType(int position){ChatMessage msg = mDatas.get(position);return msg.getType() == Type.INPUT ? 1 : 0;}@Overridepublic int getViewTypeCount(){return 2;}

getViewTypeCount返回的就是种类数目了；getItemViewType依据当然Item的position决定返回不同的整型变量。然后在getView中，依据消息的类型去载入不同的Item布局就可以。

基本上也就完工了，没啥技术含量，纯属娱乐。各位程序员兄，没事能够花点时间写下玩一玩~劳逸结合下~
