(Activity) is only responsible for handling the user interaction, and the data-related logical operations are given to presenter to do, and presenter call model after processing the data, The view display information is updated through the view's abstract interface. This enables a complete decoupling of the UI and logical operations.However, this view is also standing in the context of the app's local code to look at, for small apps completely unnecessary, large-scale apps and interactive compl

Perform gpio operations in Linux: For operating systems that do not support virtual memory and do not use the operating system to operate gpio to directly read and write the corresponding gpio register, but in operating systems such as Linux, both the kernel layer and the application layer are in virtual addresses, while the gpio registers are in physical address

PetShop and nhib.pdf must be familiar to developers on the. Net platform. The former is a classic software development architecture, and the latter is a powerful ORM framework. Recently, some of the functions of a project need To be changed from SQL Server data To Oracle data. The original DAL layer is implemented using the LINQ To SQL method, microsoft's LINQ does not provide the ing function to Oracle (Here we despise MS). If you want to change it

Many friends are not familiar with the T4 template. It helps us reduce the workload, improve our development efficiency, and reduce the probability of errors during project development. Therefore, it is very important for developers to learn the application of T4 templates. There are too many introductions and materials for the T4 template in the garden, so I will not detail the basic knowledge here, just talk about the specific
