本文主要利用圖靈機器人的接口，所做的一個簡單的智能問答機器人

實現(xiàn)

由于發(fā)送與接收消息都是不同的listView，所以要用有兩個listVeiw的布局文件

接收消息布局文件

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

發(fā)送消息布局文件

<?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_send_createDate"style="@style/chat_date_style"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="2012-09-01 18:30:21" /><RelativeLayout android:layout_width="fill_parent"android:layout_height="wrap_content" ><LinearLayout android:id="@+id/ly_chat_icon"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignParentRight="true"android:layout_marginLeft="10dp"android:orientation="vertical" ><ImageView android:id="@+id/chat_send_icon"android:layout_width="49dp"android:layout_height="49dp"android:src="@drawable/my" /><TextView android:id="@+id/chat_send_name"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center"android:text="鴻洋"android:textSize="18sp" /></LinearLayout><TextView android:id="@+id/chat_send_content"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_toLeftOf="@id/ly_chat_icon"android:background="@drawable/chat_send_msg"android:clickable="true"android:focusable="true"android:gravity="center_vertical"android:lineSpacingExtra="2dp"android:minHeight="50dp"android:text="有大嗎。。。"android:textColor="#000"android:textSize="18sp" /></RelativeLayout></LinearLayout>

MainActivity實現(xiàn)

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;/*** 存儲聊天消息*/private List<ChatMessage> mDatas = new ArrayList<ChatMessage>();/*** 適配器*/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，很高興為您服務(wù)"));}public void sendMessage(View view){final String msg = mMsg.getText().toString();if (TextUtils.isEmpty(msg)){Toast.makeText(this, "您還沒有填寫信息呢...", 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("");// 關(guān)閉軟鍵盤InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);// 得到InputMethodManager的實例if (imm.isActive()){// 如果開啟imm.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT,InputMethodManager.HIDE_NOT_ALWAYS);// 關(guān)閉軟鍵盤，開啟方法相同，這個方法是切換開啟與關(guān)閉狀態(tài)的}new Thread(){public void run(){ChatMessage from = null;try{from = HttpUtils.sendMsg(msg);} catch (Exception e){from = new ChatMessage(Type.INPUT, "服務(wù)器掛了呢...");}Message message = Message.obtain();message.obj = from;mHandler.sendMessage(message);};}.start();}}

消息ListView的adapter，根據(jù)類型的不同inflate不同的布局文件

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

獲取消息的工具類,暴露出去的，就是sendMsg這個靜態(tài)方法，當然將返回的數(shù)據(jù)也直接封裝成了ChatMessage

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";/*** 發(fā)送一個消息，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("該功能等待開發(fā)...");}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請求，獲得返回數(shù)據(jù)* @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("服務(wù)器連接錯誤！");}} catch (Exception e){e.printStackTrace();throw new CommonException("服務(wù)器連接錯誤！");} 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();}}}
