I am trying to implement SwipeListView using Pull-to-Refresh on a ListView . it is successfully integrated, but after it adds one element to the list. viewing the list is not refreshing. and no items are added to the list.

I have implemented SwipeListView from here and Pull to Refresh from here . how can i add multiple items to the list and update the list after adding the item. JAVA code

This is not a direct solution, but I had to do something similar to what I ultimately did using the built-in android PullToRefresh called SwipeRefreshLayout , which is in the support library: https://developer.android.com/ reference / android / support / v4 / widget / SwipeRefreshLayout.html . Then I used SwipeListView from https://github.com/47deg/android-swipelistview , which ended up blending perfectly.
