学习android开发有一段时间了，一直也没有做出什么有意思的软件，学校放假闲来无事，写些软件，用以对之前学过的知识的巩固。
这个软件的名字是女朋友起的，就凑合着用吧 哈哈....
下面进入正题了
软件总体构架如图
1.语音输入识别
public class SpeechRecognition {
private Intent intent = null;
private static final int VOICE_RECOGNITION_REQUEST_CODE = 4321;
Activity activity;
public SpeechRecognition(Context context){
activity = (Activity)context;
}
public void start(){
intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "开始语音");
activity.startActivityForResult(intent,VOICE_RECOGNITION_REQUEST_CODE);
}
}
2.模拟Http请求
public class HttpTools {
static int TIMEOUT = 5000;//默认超时时间
static String CHARSET = "iso-8859-1";//默认字符编码
static String TYPE = "text/html";//默认接收的html类型
static String SRCLANGUAGE = "zh-CN";//默认的语言源
static String TARGETLANGUAGE = "en";//默认翻译的目标语言targetLanguage;
static String TTSLANGUAGE = "en";//默认的发音语言
public static InputStream getInputStreamFromUrl(String urlString)
throws IOException {
return HttpTools.getInputStreamFromUrl(urlString, CHARSET);
}
public static InputStream getInputStreamFromUrl(String urlString,
String charset) throws IOException {
return HttpTools.getInputStreamFromUrl(urlString, charset, TIMEOUT);
}
public static InputStream getInputStreamFromUrl(String urlString,
String charset, int timeout) throws IOException {
return HttpTools.getInputStreamFromUrl(urlString, charset, TYPE,
timeout);
}
/*
* 函数功能：从传入的URL中得到一个InputStream流对象
* 输入参数: urlString URL地址
* charset 编码类型
* type 接收的类型
* timeout http请求超时时间
* 返回值类型:InputStream
* 创建人:twt
* 2012.7.21
*/
public static InputStream getInputStreamFromUrl(String urlString,
String charset, String type, int timeout) throws IOException {
if (urlString == null || urlString.length() == 0) {
return null;
}
// 判断url地址是https 还是http
urlString = (urlString.startsWith("http://") || urlString
.startsWith("https://")) ? urlString : ("http://" + urlString)
.intern();
// 构造一个URL对象
URL url = new URL(urlString);
// 打开一个到URL对象的连接
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty(
"User-Agent",
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727)");// 增加报头，模拟浏览器，防止屏蔽
conn.setRequestProperty("Accept", type);// 只接受text/html类型，当然也可以接受图片,pdf,*/*任意，就是tomcat/conf/web里面定义那些
// 设置超时时间
conn.setConnectTimeout(timeout);
try {
if (conn.getResponseCode() != HttpURLConnection.HTTP_OK) {
return null;
}
} catch (IOException e) {
return null;
}
// 从HttpURLConnection对象中得到输入流
InputStream input = conn.getInputStream();
return input;
}
/*
* 函数功能：以String的形式从inputStream流中取回数据
* 输入参数: InputStream
* 返回值类型:String
* 创建人:twt
* 2012.7.21
*/
public static String getStringsFromInputStream(InputStream is,
String charset) throws UnsupportedEncodingException, IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(is,
charset));
String line = null;
StringBuffer sb = new StringBuffer();
while ((line = reader.readLine()) != null) {
sb.append(line).append("\r\n");
}
if (reader != null) {
reader.close();
}
return sb.toString();
}
public static String getStringsFromInputStream(InputStream is)
throws UnsupportedEncodingException, IOException {
return HttpTools.getStringsFromInputStream(is, CHARSET);
}
/*
* 函数功能：以byte[]的形式从inputStream流中取回数据
* 输入参数: InputStream
* 返回值类型:byte[]
* 创建人:twt
* 2012.7.21
*/
public static byte[] getBytesFromInputStream(InputStream is)
throws IOException {
byte[] buf = new byte[1024 * 4];// 缓冲区
byte[] temp = new byte[1024 * 128];// 用来临时保存从缓冲区中得到的数据
int readLength = 0;// 从缓冲区读到的数据的实际长度
int totalLength = 0;// 从缓冲区取得的数据总长度
while (((readLength = is.read(buf)) != -1)) {
// 累加从缓冲区取得的数据长度
// 将从缓冲区得到的数据临时保存在temp数组中
System.arraycopy(buf, 0, temp, totalLength, readLength);
totalLength += readLength;
}
// 根据从缓冲区取得的数据总长度构造一个数组
byte[] bytes = new byte[totalLength];
// 将从temp数组中的数据复制到bytes中
System.arraycopy(temp, 0, bytes, 0, totalLength);
return bytes;
}
}
3.翻译

static String TTSLANGUAGE = "en";// 默认的发音语言
/*
* 从http请求得到的结果中提取翻译后的结果
* 输入参数：s Http请求结果字符串
* 返回值：String 类型 翻译后的字符串
* 创建人:twt
* 2012.7.21
* 例："how are you"的google翻译
* 传入参数: [[["你怎么样","how are you","Nǐ zěnme yàng",""]],[["词组",["你好"],[["你好",["How are you"]]]]],"en",,[["你怎么样",[5],0,0,1000,0,3,0]],[["how are~~V you",4,,,""],["how are you",5,[["你怎么样",1000,0,0],["你好吗",0,0,0],["你怎么",0,0,0]],[[0,11]],"how are you"]],,,[["en"]],3]
返回的结果：你怎么样
*/
public static String getTranslateResult(String s) {
return s.substring(4, s.indexOf('"', 4));
}
/*

4.语音输出
public class Tts {

//"http://translate.google.com.tw/translate_tts?ie=UTF-8&q=you&tl=en&prev=input";
