把TXT文件的路径获取下来然后通过这个函数就可以得出UTF8的string 类型然后再把它显示到屏幕。

public String getTextByUTF(String name) {   //name是TXT文件的URL
  String strReturn = "";
  int ic;
  InputStream in = null;
  ByteArrayOutputStream baos = new ByteArrayOutputStream();
  DataOutputStream dos = new DataOutputStream(baos);
  byte[] myData;
  byte[] buffer = new byte[128];
  try {

   fconn=(FileConnection)Connector.open(name,Connector.READ);
   in =fconn.openInputStream();

   if (in != null) {
    while ((ic = in.read(buffer)) > 0) {

     dos.write(buffer, 0, ic);
    }
    myData = baos.toByteArray();
    strReturn = new String(myData, "UTF-8");
    in.close();
   }
   dos.close();
   baos.close();
  } catch (Exception e) {
   System.out.println("getTextByUTF Error:" + e.toString());
  } finally {
   in = null;
   dos = null;
   baos = null;
   try
   {
   fconn.close();
   }
   catch(Exception e)
   {

   }
  }
  return strReturn;
}
