Android學習筆記之讀取檔案內容亂碼問題

public String download(String Url) throws IOException{StringBuffer stringbuffer = new StringBuffer();String line = null;BufferedReader br = null;// 建立一個URL對象    url = new URL(Url);    // 建立一個Http串連    HttpURLConnection httpurlconnection =(HttpURLConnection)url.openConnection();    // 使用IO流讀取資料    br = new BufferedReader(new InputStreamReader(httpurlconnection.getInputStream(),"GB2312"));    while((line = br.readLine())!= null){    stringbuffer.append(line);    }    br.close();    return stringbuffer.toString();}

最重要的是這句：br = new BufferedReader(new InputStreamReader(httpurlconnection.getInputStream(),"GB2312"));

後面加了一個參數："GB2312"
