Swipeleft for deletion does not work in extended elevation view

Question

The application I am creating has an extensible list view in which I have added a scroll option for editing and deleting. I added this option, but when I launch the application, it does not display the swipe option, even if I have tried with a different kind of list, but it works fine there. I used the swipe option inside the base adapter, can someone tell me why the scroll function does not work in the expanded list view.

Expandablelistview:

public class ExpandableHeightListView extends ListView { private static final int TOUCH_STATE_NONE = 0; private static final int TOUCH_STATE_X = 1; private static final int TOUCH_STATE_Y = 2; public static final int DIRECTION_LEFT = 1;
