     * AdapterView has been clicked.

     */

    public interface OnItemClickListener {

        /**

         * Callback method to be invoked when an item in this AdapterView has

         * been clicked.

         * <p>

         * Implementers can call getItemAtPosition(position) if they need

         * to access the data associated with the selected item.

         *

         * @param parent The AdapterView where the click happened.

         * @param view The view within the AdapterView that was clicked (this

         *            will be a view provided by the adapter)

         * @param position The position of the view in the adapter.

         * @param id The row id of the item that was clicked.
