PS：有些网站 弄下来之后是中文是乱码， why？
我一遇到编码问题就头晕 @@@
String dataString = ""; String urlString = "http://www.qidian.com/BookReader/1995036.aspx";try { URL url = new URL(urlString); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); InputStreamReader in = new InputStreamReader(conn.getInputStream(),"GB2312"); BufferedReader buffer = new BufferedReader(in); String inputString = "";while ((inputString = buffer.readLine()) != null) { dataString += inputString + "\n"; }in.close(); conn.disconnect(); } catch (Exception e) { System.out.println(e.getMessage() + ""); } setContentView(R.layout.main); TextView tv = (TextView) this.findViewById(R.id.textView);//dataString = FormatStr(dataString); tv.setText(dataString);
InputStreamReader in = new InputStreamReader(conn.getInputStream(),"GB2312"); 通过这样重新编码后 显示出来这个网页中文没有乱码
但是 当我把urlString 换成百度的时候 又有乱码了············坑爹 百度的是要用UTF-8 才不会有中文乱码！！
PS:跪求一劳永逸的解决方案,有没有一种方法能够获得网站的网页编码格式啊······················
