Today, I thought I would show you a simple example of how to implement pull to refresh for TListView. This example doesn’t use a data source, but instead just adds 20 items to my list every time I try to refresh it. I am currently using one timer with this sample, but you could add another one for when the data is done loading to hide the animation at that time.
click on the image and see how do it
