(Suppose you have 100 pieces of data to display in the ListView. It is not good to display them at one time. So we thought: if I display 20 pieces of data each time, when users need to see more data, they can slide the screen with their fingers. When they slide to the bottom of the screen, the ListView automatically loads 20 pieces of data. Stop until 100 pieces of data are loaded. This example just implements this function. There are specific comments in it. I hope it can give you some help.)
