因为一直以来对社交类App感兴趣，所以最近研究了一下图灵的智能聊天机器人。

首先，在首页我们需要为listviwe中填充数据。并且，需要加载一条欢迎的数据。

代码：

public class MainActivity extends Activity {

private EditText mMsg;

private ListView mchatlistView;

private MyAdapter adapter;

private List<ChatMessage> mdatas=new ArrayList<ChatMessage>();

private Handler handler=new Handler(){

public void handleMessage(Message msg) {

ChatMessage from=(ChatMessage) msg.obj;

mdatas.add(from);

adapter.notifyDataSetChanged();

mchatlistView.setSelection(mdatas.size()-1);

};

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

requestWindowFeature(Window.FEATURE_NO_TITLE);//设置无标题

setContentView(R.layout.main_chatting);

initview();

}

private void initview()

{

mMsg=(EditText) findViewById(R.id.id_chat_msg);

mchatlistView=(ListView) findViewById(R.id.id_chat_listView);

mdatas.add(new ChatMessage(Type.INPUT,"我是小貔貅，很高兴为您服务！"));

adapter=new MyAdapter(mdatas,MainActivity.this);

mchatlistView.setAdapter(adapter);

}

public void sendMessage(View view)

{

final String message=mMsg.getText().toString().trim();

if(TextUtils.isEmpty(mMsg.getText()))

{

Toast.makeText(this,"您还没有填写任何信息啦！", 0).show();

return ;

}

ChatMessage to=new ChatMessage(Type.OUTPUT,message);

to.setDate(new Date());

mdatas.add(to);

adapter.notifyDataSetChanged();

mchatlistView.setSelection(mdatas.size()-1);

mMsg.setText("");

//关闭软键盘

InputMethodManager imm=(InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

if(imm.isActive())

{

imm.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, InputMethodManager.HIDE_NOT_ALWAYS);

}

new Thread(){

public void run()

{

ChatMessage from=null;

try {

from=TulingUtils.sendmsg(message);

} catch (Exception e) {

from=new ChatMessage(Type.INPUT,"服务器挂了啦!");

/*from.setText("服务器挂了啦！");

from.setType(Type.INPUT);*/

}

Message msg=Message.obtain();

msg.obj=from;

handler.sendMessage(msg);

}

}.start();

}

在我们发送完消息以后，是需要服务器为我们返回数据的，所以这里我们需要建一个帮助类，用于访问服务器，并返回数据。

代码：

//此类用于访问开放的API

public class TulingUtils {

private static String API_KEY = "534dc342ad15885dffc10d7b5f813451";

private static String URL = "http://www.tuling123.com/openapi/api";

private static ByteArrayOutputStream baos;

public static ChatMessage sendmsg(String msg)

{

ChatMessage cm=new ChatMessage();

String url=setParams(msg);

String res=doGet(url);

Gson gson = new Gson();

Result result=gson.fromJson(res, Result.class);

if(result.getCode()>4000000||result.getText()==null||result.getText()=="")

{

cm.setText("该功能等待开发。。。");

}else

{

cm.setText(result.getText());

cm.setDate(new Date());

cm.setType(Type.INPUT);

}

return cm;

}

//get方式访问网络

private static String doGet(String url2) {

//创建一个Url

URL url=null;

HttpURLConnection conn=null;

InputStream is=null;

try {

url=new URL(url2);

conn=(HttpURLConnection)url.openConnection();

conn.setRequestMethod("GET");

conn.setConnectTimeout(5000);

conn.setReadTimeout(5000);

int code=conn.getResponseCode();

if(code==200)

{

baos = new ByteArrayOutputStream();

is=conn.getInputStream();

byte[] b=new byte[128];

int len=-1;

while((len=is.read(b))!=-1)

{

baos.write(b, 0, len);

}

baos.flush();

return baos.toString();

}else

{

throw new CommonException("连接服务器错误！");

}

} catch (Exception e) {

e.printStackTrace();

throw new CommonException("连接服务器错误！");

}

finally{

if(is!=null)

{

try {

is.close();

} catch (IOException e) {

e.printStackTrace();

}

if(baos!=null)

{

try {

baos.close();

} catch (IOException e) {

e.printStackTrace();

}

conn.disconnect();

}

//拼接URL

private static String setParams(String msg) {

try {

msg=URLEncoder.encode(msg,"UTF-8");

} catch (Exception e) {

e.printStackTrace();

}

return URL+"?key="+API_KEY+"&info="+msg;

}
