Double-buffered plotting analysis1. Principles of Windows DrawingWe see various elements in the Windows environment, such as menus, buttons, windows, images, which are basically "painted". At this point, the screen is equivalent to a blackboard, and the various GDI elements under Windows, such as brushes, brush, etc., are equivalent to colored chalk. When we hand-draw on the blackboard, it is a stroke, and so is the computer. It's just that the speed of the computer is much faster than the manua

Introduction to coordinate systemIllustrates the Java coordinate system. The coordinate origin is in the upper-left corner, in pixels, which is the smallest display unit on the computer screen. In the Java coordinate system, the first is the x-coordinate, which indicates that the current position is horizontal, the origin of the coordinates is x pixels, and the second is the y-coordinate, which indicates that the current position is in the vertical direction, and y pixels from the origin of the

PrefaceAn excellent application is not only to have attractive features and interactions, but also to have high performance requirements. Mobile phone running Android system, although the configuration in the continuous upgrade, but still can not be compared with the PC, the PC does not have the same large memory and high-performance CPU, so in the development of Android applications can not be unlimited use of CPU and memory, Improper use of CPU and memory can also cause problems such as applic
