Most Android controls inherit from the view type. Therefore, they generally inherit the View class when using custom controls. However, for highly efficient, game-level graphics, or players, the common view class isThe surfaceview class is required at this time. Because it is relatively advanced, it is recommended to install B. Simply inheriting from the surfaceview class is not acceptable, and a surfaceholder must be implemented. callback interface i
