    JSONObject json = jParser.getJSONFromUrl(PRODUCTLIST_URL);


    try {


        order = json.getJSONArray(GET_PRODUCT);

        for (int i = 0; i < order.length(); i++) {

            JSONObject c = order.getJSONObject(i);

            String id = c.getString(GET_ID);

            String brand = c.getString(GET_BRAND);

            String category = c.getString(GET_CATEGORY);

            String description = c.getString(GET_DESCRIPTION);

            String code = c.getString(GET_CODE);

            String quantity = c.getString(GET_QUANTITY);

            String unit = c.getString(GET_UNIT);

            String unitprice = c.getString(GET_UNITPRICE);

            HashMap<String, String> map = new HashMap<String, String>();

            map.put(GET_ID,id);

            map.put(GET_BRAND, brand);

            map.put(GET_CATEGORY, category);

            map.put(GET_DESCRIPTION, description);

            map.put(GET_CODE, code);

            map.put(GET_QUANTITY, quantity);

            map.put(GET_UNIT, unit);

            map.put(GET_UNITPRICE, unitprice);


            orderlist.add(map);

        }

    } catch (JSONException e) {

        e.printStackTrace();

    }

}

To iterate through your ArrayList with HashMap and show the data on an AlertDialog, try something like:

ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String, String>>();

StringBuilder sb = new StringBuilder();

for (HashMap map : list) {
    Iterator it = map.entrySet().iterator();

    while (it.hasNext()) {
        sb.append(((Map.Entry) it.next()).getValue()).append(" ");
    }
    sb.append("\n"); // Use this if you want a line break.
}

String msg = sb.toString();

new AlertDialog.Builder(this)
        .setTitle("Product details")
        .setCancelable(false)
        .setMessage(msg)
        .setPositiveButton("CLOSE", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                // Do something.
                dialogInterface.dismiss();
            }
        }).show();

This will show all the information in one AlertDialog.

If you really want to show them all in one single line, remove this line of code: 

sb.append("\n"); // Use this if you want a line break.

StringBuilder sb = new StringBuilder();
    for (HashMap<String,String> product:orderList){
        for (Map.Entry entry:product.entrySet()){
            sb.append(entry.getValue()).append(" ");
        }
    }
String msg = sb.toString();
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
        builder.setTitle("Product details")
                .setMessage(msg)
                .setCancelable(false)
                .setPositiveButton("CLOSE", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        dialogInterface.dismiss();
                    }
                }).create().show();
