Android: an efficient UI is a popular UI (2)Preface in the previous blog, I introduced two methods to optimize the UI design. The first one is to use as few components as possible to implement the layout function, the second is to use the

multithreading from time to time, all of which are my own summary of some practices, hoping to be further written. Now, go to the topic. To understand the multi-thread mechanism of Android, let's start with the entire Android architecture.Software Stack Applications Application Layer, including programs written using the Java library and Android fra

without having to develop one yourself. Your application does not have to be incorporated into other application code or linked to it. Instead, it just launches other application blocks when the demand is generated.For this job, when any part of the application is requested, the system must be able to start the process of an application and instantiate the Java object for that part. Therefore, unlike most other system applications, Android applicatio

are no special requirements, you can use the system-defined ID, as shown below. Android: Id = "@ Android: ID/List"Android: layout_width = "fill_parent"Android: layout_height = "fill_parent"/> To reference the System ID in an XML file, you only need to add th

your application needs to display a scroll list of images, and other applications have developed a suitable scroll bar that can be used by other applications, you can call this scroll bar to work without having to develop one by yourself. Your application does not need to be incorporated into or linked to other application code. On the contrary, when the demand arises, it only starts other application blocks. For this operation, when any part of the

independently of the code of all other applications. By default, each application is assigned a unique Linux User ID. Set permissions to files for each application to be visible only to users and applications themselves-although there are some ways to expose them to other applications. It is possible to set two applications to share a user ID, in which case they can see the other party's file. To save system resources, applications with the same ID can share the same VM in the same Linux Proc
