Multiple Selection Listview in Android?

• In this example, we will create a ListView with multiple selection mode with button click event. On button click event, we retrieve the selected list view items and create a Bundle with array of selected items and store it in Intent and start another activity (ResultActivity).
• ResultActivity retrieves the array and displays the result in ListView.

        ArrayList<String> selectedItems = new ArrayList<String>();

        for (int i = 0; i < checked.size(); i++) {

            // Item position in adapter

            int position = checked.keyAt(i);

            // Add sport if it is checked i.e.) == TRUE!

            if (checked.valueAt(i))

                selectedItems.add(adapter.getItem(position));

        }

        Intent intent = new Intent(getApplicationContext(),  ResultActivity.class); 

        // Create a bundle object

        Bundle b = new Bundle();

        b.putStringArray("selectedItems", outputStrArr); 

        // Add the bundle to the intent.

        intent.putExtras(b); 

        // start the ResultActivity

        startActivity(intent);

    }

}
