(To monitor screen contact events in game development, you need to rewrite the parent onTouchEvent method in View. In the rewritten method, you can intercept some information about the user's contact with the screen, such as the X and Y coordinates of the contact screen, the events of the contact screen, the contact press, the contact lift, the contact movement, the time of the contact screen, etc. Let's first look at the function prototype of onTouchEvent.)
