Custom controls write controls to their own needs. Android's own controls sometimes don't meet your needs, and at this point we can only implement the controls that fit the project. At the same time, Android allows you to inherit existing controls or implement your own controls to optimize the interface and create a richer user experience. In the usual project, we artificially divide the

The Andoird uses Android's own components, like Slidingdrawer and drawerlayout, are drawer-effect menus, but many of the items to be implemented have been limited by these self-contained components of Android, which makes it difficult to meet the requirements of the project. Custom components, all aspects under their own control, so as to make adjustments to the requirements. To achieve good results, basica
