+ * the listener is responsible for correctly determining when to actually
+ * initiate a refresh of its content. If the listener determines there should
+ * not be a refresh, it must call setRefreshing(false) to cancel any visual
+ * indication of a refresh. If an activity wishes to show just the progress
+ * animation, it should call setRefreshing(true). To disable the gesture and
+ * progress animation, call setEnabled(false) on the view.
+ * <p>
+ * This layout should be made the parent of the view that will be refreshed as a
+ * result of the gesture and can only support one direct child. This view will
+ * also be made the target of the gesture and will be forced to match both the
+ * width and the height supplied in this layout. The SwipeRefreshLayout does not
+ * provide accessibility events; instead, a menu item must be provided to allow
+ * refresh of the content wherever this gesture is used.
