Android setMultiChoiceItems

Question

When I click a button a dialog pops up with multiple selection checkbox. When I select and click on ok it pops up another dialog with selected item.If i close the dialog by clicking outside the dialog and again press the button to show the dialog to select and select and click ok it appends the result from previous selection. I don't want to append the result. What am I not understanding or making mistake? code is here

@Override
    public View onCreateView(final LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        final View view = inflater.inflate(R.layout.fragment_tab2, container, false);
        Button button = (Button) view.findViewById(R.id.displayBox);
        final List<String> selectedItems = new ArrayList<String>();
        final String[] itemList = {"Item1", "Item2", "Item3", "Item1", "Item2", "Item3", "Item1", "Item2", "Item3", "Item1", "Item2", "Item3"};
        final AlertDialog.Builder builder = new AlertDialog.Builder(view.getContext());
        builder.setTitle("Multi Select");
        builder.setMultiChoiceItems(itemList, null, new DialogInterface.OnMultiChoiceClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                if (isChecked) {
                    selectedItems.add(itemList[which].toString());
                }
            }
        }).setPositiveButton("Ok", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                ListView listView = new ListView(view.getContext());
                listView.setAdapter(new ArrayAdapter<String>(view.getContext(), android.R.layout.simple_list_item_1, selectedItems));
                Dialog dialog1 = new Dialog(view.getContext());
                dialog1.setTitle("Selected Informations");
                dialog1.setContentView(listView);
                dialog1.show();
            }
        });
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                builder.show();
            }
        });
        return view;

Try this,

ListView listView = new ListView(view.getContext());
                listView.setAdapter(new ArrayAdapter<String>(view.getContext(), android.R.layout.simple_list_item_1, selectedItems));

//Clear your listview

selectedItems.clear();

            Dialog dialog1 = new Dialog(view.getContext());
            dialog1.setTitle("Selected Informations");
            dialog1.setContentView(listView);
            dialog1.show();

Thanks it worked but if i modify my code as follows .. button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { selectedItems.clear(); builder.show(); } }); But one more problem I faced that is suppose I selected Item 1, Item2 and Item and unselect any of the item ..and click ok the other dialog shows Item1,Item2 and Item 3,,, why? – Dilip Nov 16 '15 at 06:41
yes because ur r adding ur item to list oncheck and u r not removing it from the list while unchecking. Remove your items while unchecking from the list – Neha Tyagi Nov 16 '15 at 06:48
