How do I add a layout in Android?

Right-click the layout folder. In the context menu that appears, select New > Layout Resource File. Click the + button, and then click Layout Resource File.
What is the layout editor?
The Layout Editor enables you to quickly build View -based layouts by dragging UI elements into a visual design editor instead of writing layout XML. The design editor can preview your layout on different Android devices and versions, and you can dynamically resize the layout to be sure it works properly on different screen sizes.
What is a layout manager in Android?
When we design the user interface of our application, we decide what components we will use and how we will organise those components in the application. To organise our components, we use specialised non visible objects called layout managers. There are several layout managers in Android. A LinearLayout lines up its views in one row or column.

Write The XML

Using Android's XML vocabulary, you can quickly design UI layouts and thescreen elements they contain, in the same way that you create web pages in HTMLwith a series of nested elements. Each layout file must contain exactly one root element, which must be aView or ViewGroup object. After you define the rootelement, you can add additional layout obj

Load The XML Resource

When you compile your app, each XML layout file is compiled into aView resource. Load the layout resource in your app'sActivity.onCreate()callback implementation. Do so by callingsetContentView(),passing it the reference to your layout resource in the form:R.layout.layout_file_name. For example, if your XMLlayout is saved as main_layout.xml, load i

Attributes

Every View and ViewGroup object supports its ownvariety of XML attributes. Some attributes are specific to a Viewobject. For example, TextView supports the textSizeattribute. However, these attributes are also inherited by any Viewobjects that extend this class. Some are common to all Viewobjects, because they are inherited from the root View class

Layout Position

A view has rectangular geometry. It has a location, expressed as a pair ofleft and topcoordinates, and two dimensions, expressed as awidth and height. The unit for location and dimensions is the pixel. You can retrieve the location of a view by invoking the methodsgetLeft()andgetTop().The former returns the left (x) coordinate of the rectangle repr

Size, Padding, and Margins

The size of a view is expressed with a width and height. A view has two pairsof width and height values. The first pair is known as measured width andmeasured height. These dimensions define how big a view wants to bewithin its parent. You can obtain the measured dimensions by callinggetMeasuredWidth()andgetMeasuredHeight(). The second pair is know

Common Layouts

Each subclass of the ViewGroup class provides a unique way todisplay the views you nest within it. The most flexible layout type, and the onethat provides the best tools for keeping your layout hierarchy shallow, isConstraintLayout. The following are some of the common layout types built into the Androidplatform. developer.android.com
