try this code

 URL url = new URL(urlpath);
 BufferedInputStream bis = new BufferedInputStream((url.openStream()));
 DataInputStream dis = new DataInputStream(bis);
 String full = "";
 String line;
 while ((line=dis.readLine())!=null) {
     full +=line;               
  }      
bis.close();
dis.close();

((TextView)tv).setText(full);

try this function ....

 public static String convertStreamToString(InputStream is) throws Exception {
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        StringBuilder sb = new StringBuilder();
        String line = null;

        while ((line = reader.readLine()) != null) {
            sb.append(line);
        }

        is.close();

        return sb.toString();
    }
