The interface display on Android is implemented through activity, and activity is too common. But activity also has its limitations, the same interface on the phone may look good, on the tablet is not necessarily, because the tablet screen is very large, the phone's interface on the tablet may be excessively stretched, the control spacing is too large, and so on. This is a better time to experience the effect of embedding "small activity" in activity, and then each "small activity" can have its

Start A Fragment is a piece of an application‘s user interface or behavior that can be placed in an Activity. Interaction with fragments is done through FragmentManager, which can be obtained via Activity.getFragmentManager() and Fragment.getFragmentManager(). with a paragraph referencing the APIThat means that fragment is a fragment of the activity that makes up

The ability to add, delete, replace, and use them in activity to perform other responses to user interactions is a great feature of fragment. Each set of changes you submit to the activity is called a transaction, and you can use the APIs in Fragmenttransaction to execute it. It is also possible to save each transaction to the activity-managed fallback stack and allow the user to navigate backwards (similar to the activity's backward navigation) throu

Fragment knowledge summary, fragment knowledge1. Why is Fragment called the fifth component? Fragment saves more memory than Activity, and its switching mode is more comfortable. It uses no less than four components and has its own lifecycle, and must be attached to Activity.2. How to Create

To manage fragment, you need to use fragmentmanager. To obtain it, you need to call the getfragmentmanager () method in the activity (). You can use fragmentmanager to do the above: 1. Use findfragmentbyid () or findfragmentbytag () to obtain the existing fragment in the activity. 2. Use popbackstack () to pop up fragment members from the back stack of the activ

Implementation of simple communication between fragment and fragment This article uses the most basic fragment knowledge for beginners only. It also provides basic preparation for related knowledge in the future. It would be a waste of minutes for you to take a look. For more information about fragment APIs, click here

In general, fragment is part of the overall view Hierarchy Tree of the activity and is embedded into a part of the interface of the host activity. There are two ways to add fragment to the activity layout: 1. Declare fragment in the activity layout file. You can specify layout attributes for fragment like a view. The f

The ability to add, delete, replace, and use fragment in an activity to respond to user interaction is a great feature. Each change set you submit to the activity is called a transaction, and you can use APIs in fragmenttransaction to execute it. You can also save each transaction to the rollback stack managed by the activity, and allow the user to navigate backward through the fragment change (similar to t

Java fragment and java Fragment At present, I have come into contact with the following main types of fractal: 1. Similar to the fragment of Clifford. The characteristics of this fragment are that the initial coordinate of the fragment is (0, 0). After a large number of iter

fragment, the parent control group. Finally, you need to invoke the commit () method to make the Fragmenttransaction instance change effective. Instance Examples of exercises: Write a class that inherits from the fragment class and writes its layout file (two TextView in this case) and adds the layout to the Oncreateview () method of the

Android Fragment: An Activity composed of static Fragment and androidfragment I have always been used to writing all event processing code in the Activity. I did not find that the Activity can be composed of multiple Fragment items until I carefully studied Fragment. I do not have a deep understanding of

Fragment caching refers to caching a fragment of a webpage. For example, if a page shows an annual sales summary in a table, we can store this table in the cache, reducing the time that each request needs to be re-generated. To use fragment caching, call Ccontroller::begincache () and Ccontroller::endcache () in the Controller view script. Both methods start and
