The advantage of using a relative views is that it eliminates that need for nested view groups and may improve efficiency.It is important to note in a relative layout that all components have to be ANCHORED or PINNED to its parent layout, other components, or both.When you are laying out components horizontally, you typically want to start with the one that is the tallest to serve as the anchor and give it an id name (e.g., android:id= Then, add an attribute called android:layout_alignBaseline to the other components and give them the same id name (e.g., android:layout_alignBaseline = given to the tallest component.(e.g., Vertical and Horizontal layouts WITHIN a parent Linear layout). NOTE: It is common practice to NEST layout to get the desired layout you wanted. layout_toRightOf / layout_toLeftOf / layout_above / layout_below will also position a component to another component.layout_align (Top, Bottom, Left and Right) to space components a specific amount from an edge of another component via its id.layout_margin (Top, Bottom, Left and Right) to space components a specific amount from an edge to control distance between components.NOTE: alignParentEnd use to support Right-to-Left rendering for the right side of the screen and alignParentStart for the left side of the screen. layout_alignParent (Top, Bottom, Left and Right, End and Start) to align and anchor components to an edge (true or false).layout_centerHorizontal / layout_centerVertical to align components to the center.
It is where children components are aligned “RELATIVE” to its parent’s center or edge, other sibling components or both that allows more freedom to where components can be positioned based on attributes: RelativeLayout is the most versatile layout type. TIP: Look at the icons in the screenshot below to “see” how components are layout. However, there a few other layouts that are used. Layouts are top-level containers for components or other layouts that are available in two main types (Linear and Relative). It also offers localization support by changing the locale property in the Preview panel (e.g., Left-to-right (LTR) or Right-to-left (RTL)).

The Layout Editor allows you to type or drag-and-drop UI components from the Palette panel to create XML code that can then be edited either in Design (Graphical) or Text (XML) that can be previewed on multiple screen sizes and devices.
