Get ID from SQLite when button clicked

This is part of my app screenshot.

When I click the DELETE button, I want it to delete the row of SQLite based on the ID. I tried below code but it always give me value 0.

 delete.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int itemCount = listview.getCount();
                for (int i = itemCount - 1; i >= 0; i--) {
                    SearchList search = adapter.getItem(i);
                    int id = search.getID(); // get the list id from sqlite if check box is checked
                    if (search.isSelected()) {
                        adapter.removeItem(i); //remove the list item if checkbox is checked
                        delete.setText("DELETE");
                        checkBoxCounter = 0;
                        Toast.makeText(getApplication(),id+"",Toast.LENGTH_SHORT).show();
                    }
                }
            }
        });
