gravity: The gravity attribute specifies how a View is aligned within its parent View or ViewGroup. In this step, you center the TextView to be centered vertically within the parent ConstraintLayout.

Set the background attribute to @color/colorPrimary. (As you enter @c, choices appear for easy selection.)

As a result of changing the width control, the layout_width attribute in the Attributes pane shows the value match_constraint and the Button element stretches horizontally to fill the space between the left and right sides of the layout.

Explore the layout editor, and refer to the figure below as you follow the numbered steps:

View: a rectangle area on the screen, responsible for drawing and event handling. Base class for widgets which are used to create interactive UI components. The ViewGorup subclass is the base class for layouts, which are invisible containers that hold other Views and define their layout properties.

View IDs need not be unique throughout the tree, but it is good practice to ensure that they are at least unique within the part of the tree you are searching.

Prorate 비례 배분하다.
Space is prorated. For example, if the button elements each have a weight of 1 and the TextView 2, totalling 4, the button elements get ¼ of the space each, and the TextView half.

All of the views in a window are arranged in a single tree. You can add views either from code or by specifying a tree of views in one or more XML layout files.

To implement a custom view, you will usually begin by providing overrides for some of the standard methods ~
