android – java.lang.RuntimeException：无法在未调用Looper.prepare()的线程内创建处理程序

progressD = ProgressDialog.show(MenuUtama.this,"","Uploading files to server.....",false);
Thread thread = new Thread(new Runnable(){
       public void run(){
           //doFileUpload();
           try {
            // setiap parameter yang akan dikirim melalui http
            // harus encode agar
            // dapat terbaca dengan baik oleh server
            Cursor c = helper.getAll1(almagId);
            Cursor cr = helper.getUpImage(almagId);
                if(c.movetoFirst()){
                    //progressD = ProgressDialog.show(context,title,message)
                        do{
                            String kdstore = URLEncoder.encode(helper.getKdStore(c).toString(),"utf-8");

                            url = "http://10.234.165.232/upload_get.PHP";
                        }while(c.movetoNext());
            }
            if(cr.movetoFirst()){
                do{
                    String kdstore = URLEncoder.encode(helper.getKdstore1(cr),"utf-8");
                    String gambar = URLEncoder.encode(helper.getGam1(cr),"utf-8");

                    url1 = "http://10.234.165.232/upload_get2.PHP";
                }while(cr.movetoNext());
            }

            } catch (UnsupportedEncodingException e) {
                // Todo Auto-generated catch block
                e.printstacktrace();
            }
           MenuUtama.this.runOnUiThread(new Runnable(){
               public void run() {
                   if(progressD.isShowing())
                       progressD.dismiss();
               }
           });
       }
});
thread.start();
return(true);

和这样的错误：

FATAL EXCEPTION: Thread-9

如果活动将数据保存到服务器我命令进度条可以运行,但如果没有这不起作用..我应该怎么做才能解决这个问题？
