下拉刷新列表添加SwipeDismissListViewTouchListener实现滑动删除某一列。

《Android SwipeToDismiss：左右滑动删除ListView条目Item》

Android的SwipeToDismiss是github上一个第三方开源框架（github上的项目链接地址：https://github.com/romannurik/Android-SwipeToDismiss ）。该开源项目旨在：使得一个ListView的item在用户的手指在屏幕上左滑或者右滑时候，删除当前的这个ListView Item。

/**
 * A {@link View.OnTouchListener} that makes the list items in a
 * {@link ListView} dismissable. {@link ListView} is given special treatment
 * because by default it handles touches for its list items... i.e. it's in
 * charge of drawing the pressed state (the list selector), handling list item
 * clicks, etc.
 *
 * <p>
 * After creating the listener, the caller should also call
 * {@link ListView#setOnScrollListener(AbsListView.OnScrollListener)}, passing
 * in the scroll listener returned by {@link #makeScrollListener()}. If a scroll
 * listener is already assigned, the caller should still pass scroll changes
 * through to this listener. This will ensure that this
 * {@link SwipeDismissListViewTouchListener} is paused during list view
 * scrolling.
 * </p>
 *
 * <p>
 * Example usage:
 * </p>
 *
 * <pre>
 * SwipeDismissListViewTouchListener touchListener = new SwipeDismissListViewTouchListener(
 *         listView, new SwipeDismissListViewTouchListener.OnDismissCallback() {
 *             public void onDismiss(ListView listView,
 *                     int[] reverseSortedPositions) {

 * This class Requires API level 12 or later due to use of
