Question

Currently, I’ve been involved in an android app development related to online foodItem ordering. I’ve a listView with following schema:

itemName1  itemPrice1  checkBox
itemName2  itemPrice2  checkBox
itemName3  itemPrice3  checkBox
             .
             .
             .


          GetYourCart[Button]

My task is to keep track of each of the selected itemNames with price and total price when the user presses the button. I’ve used the SparseBooleanArray sbArray = myMenulist.getCheckedItemPositions(); but it’s not showing any result.

How can I implement this? I’ve gone through several questions asked in stackoverflow and other online tutorials but can’t get it.

Edited: Here is the code for selected items that I used to check the result:

btnyourCart.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub

                String selected = "";
                int cntChoice = myMenulist.getCount();
                SparseBooleanArray sbArray = myMenulist.getCheckedItemPositions();
                for(int i=0;i<cntChoice;i++){
                    if(sbArray.get(i)) {

                        selected += myMenulist.getItemAtPosition(i).toString() + "\n";



                    }


                }
                Log.e("menu","Items "+selected);
                Toast.makeText(getApplicationContext(), selected, Toast.LENGTH_SHORT).show();


            }
        });

Thanks in advance!

int total=0;

btnyourCart.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub

            String selected = "";
            int cntChoice = myMenulist.getCount();
            SparseBooleanArray sbArray = myMenulist.getCheckedItemPositions();
            for(int i=0;i<cntChoice;i++){
                if(sbArray.get(i)) {

                    selected += myMenulist.getItemAtPosition(i).toString() + "\n";

                     total+=myMenulist.get(i).price;

                }


            }
            Log.e("menu","Items "+selected);
            Toast.makeText(getApplicationContext(), selected, Toast.LENGTH_SHORT).show();


        }
    });

Now on button click event get total.

button.setOnClickListenernew View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            Toast.makeText(
                    this,
                    ""+total,
                    Toast.LENGTH_LONG).show();

        }
    });
