Dynamic page loading and deletion by viewpager

Many people say that the pageradapter. notifydatasetchanged () of viewpager is invalid on the Internet. At the beginning, I thought it was true, and even misled.

Later, I found out that in pageradatpar, rewrite getitemposition () and return position_none to refresh and load the drawing each time. This is the key point. In this case, if you modify "dataset", such as list, and then modify ydatasetchanged (), you will find that the interface overlaps. The solution is to rewrite destroyitem (), convert viewgroup to viewpager, and convert object to view. Finally, you can call viewgroup. removeview. PS: two days, really TMD efficiency. Haha (fuck you)
