Swipeleft to delete not working in expandable height listview

Question

The application which i am creating has an expandable list view in which i have added the option of swipe to edit and delete.I have added those option but when i run the application it doesn't shows the swipe option even i have tried with another list view but there it works fine. I have used the swipe option inside the base adapter can anyone tell me why the swipe functionality doesn't works in expandable 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;
public static final int DIRECTION_RIGHT = -1;
private int mDirection = 1;//swipe from right to left by default

private int MAX_Y = 5;
private int MAX_X = 3;
private float mDownX;
private float mDownY;
private int mTouchState;
private int mTouchPosition;
private DaybookSwipeMenuLayout mTouchView;
private OnSwipeListener mOnSwipeListener;

private DaybookSwipeMenuCreator mMenuCreator;
