All elements in the layout are built using a hierarchy of View and ViewGroup objects. A View usually draws something the user can see and interact with. Whereas a ViewGroup is an invisible container that defines the layout structure for View and other ViewGroup objects, as shown in figure 1.

Figure 1. Illustration of a view hierarchy, which defines a UI layout. The View objects are usually called "widgets" and can be one of many subclasses, such as Button or TextView.

The ViewGroup objects are usually called "layouts" can be one of many types that provide a different layout structure, such as LinearLayout or ConstraintLayout. Declaring your UI in XML allows you to separate the presentation of your app from the code that controls its behavior. Using XML files also makes it easy to provide different layouts for different screen sizes and orientations discussed further in Supporting Different Screen Sizes.

The Android framework gives you the flexibility to use either or both of these methods to build your app's UI. For example, you can declare your app's default layouts in XML, and then modify the layout at runtime. Tip: To debug your layout at runtime, use the Layout Inspector tool. Each layout file must contain exactly one root element, which must be a View or ViewGroup object.

Once you've defined the root element, you can add additional layout objects or widgets as child elements to gradually build a View hierarchy that defines your layout. After you've declared your layout in XML, save the file with the.

More information about the syntax for a layout XML file is available in the Layout Resources document. When you compile your app, each XML layout file is compiled into a View resource.

You should load the layout resource from your app code, in your Activity. Do so by calling setContentViewpassing it the reference to your layout resource in the form of: R. The onCreate callback method in your Activity is called by the Android framework when your Activity is launched see the discussion about lifecycles, in the Activities document. Some attributes are specific to a View object for example, TextView supports the textSize attributebut these attributes are also inherited by any View objects that may extend this class.

Some are common to all View objects, because they are inherited from the root View class like the id attribute. And, other attributes are considered "layout parameters," which are attributes that describe certain layout orientations of the View object, as defined by that object's parent ViewGroup object.

Any View object may have an integer ID associated with it, to uniquely identify the View within the tree. When the app is compiled, this ID is referenced as an integer, but the ID is typically assigned in the layout XML file as a string, in the id attribute. This is an XML attribute common to all View objects defined by the View class and you will use it very often.

The at-symbol at the beginning of the string indicates that the XML parser should parse and expand the rest of the ID string and identify it as an ID resource.

There are a number of other ID resources that are offered by the Android framework. When referencing an Android resource ID, you do not need the plus-symbol, but must add the android package namespace, like so:. With the android package namespace in place, we're now referencing an ID from the android. R resources class, rather than the local resources class.

Defining IDs for view objects is important when creating a RelativeLayout. In a relative layout, sibling views can define their layout relative to another sibling view, which is referenced by the unique ID.

An ID need not be unique throughout the entire tree, but it should be unique within the part of the tree you are searching which may often be the entire tree, so it's best to be completely unique when possible.View solution.

We also must believe that information alone allowed big bettors to beat Las Vegas 15 straight times. And finally we must believe the fact that Donaghy become a much more active referee recently is a coincidence rather than evidence of an effort to increase his influence on games.
