Classic diagram of activity life cycle:The impact of the key on the life cycle:Back key:When we press the back key, we will end this application, and then we will call OnPause ()->onstop ()->ondestory () three methods successively.OnCreate ()->onstart ()->onresume () is executed when the app is started againHome key:When we opened the app, like a browser, I was browsing the NBA news, and when I saw half of

You can combine multiple fragment into an activity to create a faceted interface and you can reuse a fragment in multiple activity. You can think of fragment as a modular activity that has its own life cycle, receives its own events, and can be added or deleted when it is run. The fragment cannot exist independently, it must be embedded

Every living creature has its own life cycle, from birth, adolescence, adulthood, to death. Similarly, a component has its specific life cycle, and react describes its entire life cycle in different ways. The following is a struct

From: http://blog.csdn.net/qitian67/article/details/18516503 Recently in a small example, found that the class inherits from the class of monobehaviour, there are many methods, so it is necessary to ask a question: So many methods, the implementation of the order is how it. How is the internal management? So on the internet to find a lot of information, found that Richard Fine in 2012 has published an article, and is quite deep, and very reasonable, here with some of my attempts and thinking, to

(savedInstanceState); if (savedInstanceState != null) { needSaveDraft = savedInstanceState.getBoolean("NEED_SAVE_DRAFT" ); } else { // TODO 解析Intent对象传入的参数或者Action // Intent intent = getIntent(); // intent.getBundleExtra(""); } }To reduce the burden on developers, most system controls in Android implement the logic of State caching. Before the Onsaveinstancestate function is called, the in

through the introduction of the previous blogs, we found that hibernate's implementation of persisting the business entity to the database works by "Mapping xml". So what's the origin of this XML?mapping files (HBM) The premise of a reasonable existence is the existence of a corresponding entity-the business entity.Today this blog is about the process of entity-to-database, which is a persistence process from code to data, which is the life

Many applications are now developed based on nested fragment in fragmentactivity, so if we can clearly know their life cycle, it will make our development easier.For the life cycle of the activity, I have already described it in detail in the previous article Activity life

can use the management project as the parent node directly. Example:Because the above practices will cause all projects that inherit this parent node to download the dependent packages configured by this parent node, if some projects do not have to require this dependency package, this dependency package is declared as requiring no automatic download dependencies:Then the project that inherits this parent node is not automatically downloaded:If there is a project to configure this parent node t
