图灵机器人

最近做了一个和机器人聊天的App,还没有全部做完，我先整理出基本的功能，以后慢慢加(此版本为1.0）。

功能：

1.实现网络访问

2.可以和机器人进行简单聊天

3.在bean包中封装了四个机器人毛毛的回答数据类

4.实现聊天记录的存储功能。

1.完成网络访问

首先需要第三方库资源，图灵机器人的网址：http://www.tuling123.com/ 可以设置自己的专属机器人。

下载它的API接入文档，里面有详细的请求说明，这里不赘述。

上代码

public static void doPost(final String massage,final HttpCallbackListner listner) {

final StringBuffer sbf = new StringBuffer();
new Thread(new Runnable() {
@Override
public void run() {
try {
URL url =  new URL(API_ROBOT);
HttpURLConnection connection =
(HttpURLConnection)url.openConnection();
connection.setReadTimeout(5000);
connection.setConnectTimeout(5000);
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestMethod("POST");
//规定访问需要“utf-8"模式
connection.setRequestProperty("content-type","applcation/json: charset = utf-8");
//将发送的问题，封装成一个javabean
SendMsg sm = new SendMsg();
sm.setKey(API_KRY);
//不用这种方式了
String Info = URLEncoder.encode(massage);
sm.setInfo(massage);
String msg =ParaseJson.convertJson(sm);

OutputStream out = connection.getOutputStream();

out.write(msg.getBytes());
out.flush();
BufferedReader br = new BufferedReader(new InputStreamReader(
connection.getInputStream()));

String str = null;
while ((str = br.readLine())!=null){
sbf.append(str);
}

str = sbf.toString();

Log.d("TAG","request message is"+str);

br.close();
out.close();

if (listner!=null){
String result = sbf.toString();

listner.onSuccess(result);
}

} catch (MalformedURLException e) {
e.printStackTrace();

} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
listner.onFailed(e);
e.printStackTrace();
}
}
}).start();

2 .Json数据解析

public static Object parseJson(String result)  {
List<String> list = null;

try {
JSONObject jsonobject =new JSONObject(result);
int code = jsonobject.getInt("code");
String msg = jsonobject.getString("text");
if (jsonobject.has("url")){
String url = jsonobject.getString("url");
if (jsonobject.has("list")){
JSONArray jsonArray = jsonobject.getJSONArray("list");
for (int i = 0;i<jsonArray.length();i++){
JSONObject jFather = jsonArray.getJSONObject(i);
String address = jFather.getString("detailurl");
list.add(address);
}
NewsMsg n = new NewsMsg();
n.setmCode(code);

StringBuilder sb =new StringBuilder();
sb.append(msg);

for (int k = 0; k<list.size(); k++){
sb.append(list.get(k));
}
msg = sb.toString();
n.setmMsg(msg);
return n;
}else {
LinkMsg l =  new LinkMsg();
l.setUrl(url);
l.setmCode(code);
l.setmMsg(msg+url);
return l;
}

}else {
TextMsg t =new TextMsg();
t.setmMsg(msg);
t.setmCode(code);
return t;
}

} catch (JSONException e) {
e.printStackTrace();
}
return null;
}

3 .简单聊天界面的实现

这部分代码实在太多，就捡比较重要的说，这次是仿微信界面，消息的布局分左右两种，先创建一个CheatMessageAdapter 的类让它继承BaseAdapter,然后覆写它的 getItemViewType(int position)和getViewTypeCount()方法。

@Override
public int getItemViewType(int position) {
Object object = mDates.get(position);

if (object instanceof ReturnMessage){

return 0;

}else
return 1;

}

@Override
public int getViewTypeCount() {
return 2;
}

在getView()方法里也要进行不同判断

@Override
public View getView(int position, View convertView, ViewGroup viewGroup) {
Object message = mDates.get(position);
ViewHolder mHolder = null;
if (convertView ==null) {
if (getItemViewType(position) == 0) {
convertView = mInflater.inflate(R.layout.cheat_robot_layout, null);
mHolder = new ViewHolder();
mHolder.msgText = (TextView) convertView.findViewById(R.id.id_tvt_cheat_robot);
mHolder.showTimeText = (TextView) convertView.findViewById(R.id.id_tvt_timeshow);

} else {
convertView = mInflater.inflate(R.layout.cheat_me_layout, null);
mHolder = new ViewHolder();
mHolder.msgText = (TextView) convertView.findViewById(R.id.id_tvt_cheat_me);
mHolder.showTimeText = (TextView) convertView.findViewById(R.id.id_tvt_timeshow);

}
convertView.setTag(mHolder);
}else{
mHolder = (ViewHolder) convertView.getTag();
}
if (message instanceof ReturnMessage) {
setDate(mDates.get(position),mHolder);
}else if (message instanceof CheatMessage){
setDate(mDates.get(position),mHolder);
}
return convertView;
}

private final class ViewHolder{
TextView showTimeText;
TextView msgText;
}

private void setDate(Object object,ViewHolder holder) {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
if (object instanceof CheatMessage) {
holder.showTimeText.setText(sdf.format(((CheatMessage) object).getDate()));

holder.msgText.setText(((CheatMessage) object).getMsg());
} else {
if (object instanceof ReturnMessage) {
switch (typeConvertNumber((ReturnMessage)object)) {
case 0:
holder.showTimeText.setText(sdf.format(new Date()));

holder.msgText.setText("出错了，我没有找到匹配的东西");
break;
case 1:  holder.showTimeText.setText(sdf.format(new Date()));

holder.msgText.setText(((TextMsg) object).getmMsg());
break;
case 2:holder.showTimeText.setText(sdf.format(new Date()));

holder.msgText.setText(((LinkMsg) object).getmMsg());
break;
case 3:holder.showTimeText.setText(sdf.format(new Date()));

holder.msgText.setText(((NewsMsg) object).getmMsg());
}

}
}
}
private int typeConvertNumber(ReturnMessage message){
int n = 0;
if (message instanceof TextMsg){
n=1;
return n;
}else if (message instanceof LinkMsg){
n=2;
return n ;
}else if (message instanceof NewsMsg){
n =3;
return n;
}
return 0;
}

未完待续，先写到这里，等1.0版本写完了，我会上传到github上，敬请期待。
