Today, I wrote the tab for the iPhone-like effect. For this example, refer to the Code shared by rolle3k abroad. Thanks to rolle3k. In the previous blog, we wrote an itab class, which introduced the background rendering and a simple map method. We continue to complete the itab class and put it inside the mainacitvity (inheriting activity) class. In this way, the whole program only needs one class. (For the previous blog example, you need to create a s
