                for (int i = 0; i < data.length(); i++) {
                    JSONObject c = data.getJSONObject(i);
                    map = new HashMap<String, String>();
                    map.put("id_atm", c.getString("id_atm"));
                    map.put("id_bank", c.getString("id_bank"));
                    map.put("nama_bank", c.getString("nama_bank"));
                    map.put("latitude", c.getString("latitude"));
                    map.put("longitude", c.getString("longitude"));
                    map.put("name", c.getString("name"));
                    map.put("email", c.getString("email"));

                    //end add marker

                    maps.addMarker(new MarkerOptions()
                            .title("ATM"+MyArrListATM.get(i).get("nama_bank"))
                            .snippet("24 Jam")
                            .position(new LatLng(
                                    Double.parseDouble(MyArrListATM.get(i).get("latitude")),
                                    Double.parseDouble(MyArrListATM.get(i).get("longitude")))));
                }
                progress.dismiss();
            }



        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();

            progress.dismiss();

            AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
            alertDialog.setTitle("PERINGATAN");
            alertDialog.setMessage("Error: "+e.getMessage());
            alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "TUTUP", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            });

            alertDialog.show();
        }

and i try to remove some code so the code like this

progress = ProgressDialog.show(MainActivity.this, "MOHON DITUNGGU", "Loading...", true);

and progressdialog is coming show

so how to show progressdialog with my some code like above?

Where did you call progress.show() in your code?? And can you post ProgressDialog.show()? — Saritha G, Jul 15 '16 at 06:45
short msg : Show your `ProgressDialog` in `PreExecuted` method and hide it `onPostExecute` method. — Harshad Pansuriya, Jul 15 '16 at 06:50
it's my code `progress = ProgressDialog.show(MainActivity.this, "MOHON DITUNGGU", "Loading...", true);` it's will show progressdialog but if there's not following code, if have following code that will not show — Eggy, Jul 15 '16 at 06:52
Are you using an `ASyncTask` for this? If so, go with @Ironman's proposal — 0xDEADC0DE, Jul 15 '16 at 06:57

Simply there's nothing wrong, i guess your loop execution happening so quickly that your progress dialog being dismissed even before u can see it

OR

Some exception occurred in your try block and dialog gets dismissed in catch block

Every thing is fine you just have to add some delay in thread.

Recommened: try to use AsyncTask for this type of work.

   progress = ProgressDialog.show(MainActivity.this, "MOHON DITUNGGU", "Loading...", true);
   // Execute some code after 1 seconds have passed
    Handler handler = new Handler(); 
    handler.postDelayed(new Runnable() {
         @Override 
         public void run() { 
              // YOur Request code here?

         } 
    }, 1000);

Oh yeah it's work!! but why when first progressdialog show the circle loading is run, but after that the circle loading is stuck? – Eggy Jul 15 '16 at 07:09
make sure you have `progress.dismisse();` in your code. – Sohail Zahid Jul 15 '16 at 07:12
yes i have `progress.dismiss();` . over all it's work, the problem just animated of circle loading it's just animated for maybe 1 second, after that the animated is stop – Eggy Jul 15 '16 at 07:17
ahaaa its because everything is happening in UI Thread as i recommended use AsyncTask for this type of work. – Sohail Zahid Jul 15 '16 at 07:18
if using AsyncTask, i must still using your code (handler,etc) or not? – Eggy Jul 15 '16 at 07:23

INitialize progress Dialog like this

  ProgressDialog  myProgressDialog = new ProgressDialog(this);
    myProgressDialog.setIndeterminate(true);
    myProgressDialog.setMessage("Loading...");
    myProgressDialog.setCancelable(true);

and to show progress dialog write

myProgressDialog.show();

to dismiss

myProgressDialog.dismiss();

why the progress dialog can't show?
