This article briefly discusses the architecture of future Android game engine templates. In the Android game development Tutorial II: The View class and the Surfaceview class we've talked about, Surfaceview class has a lot of advantages, so in the Android game development or choose Surfaceview. Here we inherit Surfaceview directly, implement Surfaceholder.callback interface, deal with surfacecreated, surfacechanged and Surfacedestroyed methods, Here we do not have the key to control the incomin

Rssurfaceview directly inherits from Surfaceview, and implements the Surfaceholder.callback callback interface. The parsing is as follows:1.

1. Surfaceview is the inheritance class for view, which has a built-in surface for drawing. You can control the format and size of this surface. Surfaceview controls where this surface is drawn. surface is a deep sort (z-ordered), which indicates that it is always behind its own window. The Surfaceview provides a visible area that is visible only on the surface portion of the visible area and not visible outside the visible area. The layout display of surface is affected by the view hierarchy, a

Reference: zero-based Android game programming Related knowledge points: 1, callback a surfaceview must implement a Surfaceholder.callback interface. To notify view when the underlying surface state changes, the interface needs to implement the following 3 methods: publicvoidsurfacecreated ( Surfaceholderholder) {}publicvoidsurfacechanged (SurfaceHolder Holder,intformat,intwidth,intheight) {}publicvoid surfacedestroyed (Surfaceholderholder) {}2,
