问题描述

您好，我有一个问题，我的code..my code是

hi i have a problem with my code..my code is

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");
                            String nama = URLEncoder.encode(helper.getNama(c).toString(), "utf-8");
                            String alamat = URLEncoder.encode(helper.getAlamat(c).toString(), "utf-8");
                            String kdpos = URLEncoder.encode(helper.getKdPos(c).toString(), "utf-8");
                            String notelp = URLEncoder.encode(helper.getNotel(c).toString(), "utf-8");
                            String lng = URLEncoder.encode(helper.getlng(c).toString(), "utf-8");
                            String lat = URLEncoder.encode(helper.getLat(c).toString(), "utf-8");
                            String perush = URLEncoder.encode(helper.getPerus(c).toString(), "utf-8");
                            //String gambar = URLEncoder.encode(helper.getGamb(c).toString(), "utf-8");

                            //Toast.makeText(this, kdstore, Toast.LENGTH_LONG).show();
                            //System.out.println(gambar);
                            url += "?kode_toko=" + kdstore + "&&nama=" + nama + "&&alamat=" + alamat + 
                            "&&kode_pos=" + kdpos + "&&no_telp=" + notelp + "&&longitude=" + lng + "&&latitude=" + lat +
                            "&&perusahaan=" + perush;
                            getRequest(url);
                            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 += "?kode_toko1=" + kdstore + "&&gambar1=" + gambar;
                    getRequest1(url1);
                    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
java.lang.RuntimeException: 
Can't create handler inside thread that has not called Looper.prepare()
    at android.os.Handler.<init>(Handler.java:121)

    at com.sat.alfaloc.MenuUtama$1.run(MenuUtama.java:101)
    at java.lang.Thread.run(Thread.java:1096)

如果活动服务器保存数据我所吩咐的进度条可以运行，但如果没有这种不worked..what应该怎么做来解决这个问题？

if activity save data in to server I command the progress bar can run,but if not this not worked..what should i do to fix this problem??

推荐答案

也许你正在因为你使用的是活动的范围内螺纹的错误。

Probably you are getting error because of the thread in which you are using the context of the activity.

您应该使用 AsyncTask的的，而不是一个正常的线程。 在AsyncTask的有在preExecute的方法（）和 onPostExecute（）这是执行主线程并有一个方法 doInBackground（）将在后台执行，这样就可以很容易地实现万岁过程。

You should use the AsyncTask instead of a normal thread. In AsyncTask there is a method onPreExecute() and onPostExecute() which are executing on the main thread and there is a method doInBackground() which will execute on background so that you can easily implement the long live process.

您可以参考这个例子
