Android app developers are very well familiar with the traditional layout, linear layout, and relative layout, but using these layouts may bring down your app performance.
Moreover handling complex and large layouts can be frustrating as you manually need to create some improvement in the view hierarchy with some nested views.
To solve the above problem, Google has introduced an android constraint layout editor at the Google I/O conference 2016. This new Layout Editor has a set of powerful tools that empower developers to create flat-UI hierarchies for the complex layout. This new layout is called Constraint Layout.
In this article, we will discuss the following topics to get a clear idea about constraint layout, its advantages, and how we can set up constraint layout in a few steps with DhiWise.
With constraint layout, developers can build complex and responsive user interfaces without using nested view groups, which is otherwise not possible with the relative layout. The view group used by constraint layout allows developers to position and size widgets in a flexible way.
The performance comparison between Constraint Layout and Relative Layout shows the following result.
Traditional layout vs Constraint layout
In the above performance comparison, you can see that constraint layout has 40% better performance than the traditional layout.
Further, developers can simply drag and drop view widgets from the Palette to the designer editor and create great user interfaces. Following is the list of constraint layouts currently available to use.
Thus, constraint layout helps developers to improve the performance of layout files and also provides more versatility to use layouts.
“DhiWise is a revolutionary platform that emphasizes developer empowerment through the technological advancement in web and mobile app development approach.”
DhiWise Android Builder simplifies app development with its powerful features one of them is UI constraint layout. So, the developers can create large and complex UI designs with a flat view hierarchy and improve the performance of their applications.
In the following screenshot, you can see the multiple screens that are fetched from Figma design. Here, DhiWise enables you to switch the screen view between linear layout and constraint layout using the toggle button.
Setting up Layout
By default, the view for each screen will be in Linear layout, as shown below.
After setting the layout to constraint layout, the views will be mapped accordingly as shown in the screenshot here.
With constraint layout, you can deal with the relative positioning of UI elements, handle dimension constraint, visibility behavior, circular positioning, widgets, and child views of the app.
This is how DhiWise helps you to change the layout from linear to constraint in a matter of seconds.
Further, you can set actions and views to each screen component but we will discuss that part in our next blog.
Now you know how Constraint Layout brings the dual power of Linear layout and Relative layouts while filtering out their limitations.
DhiWise Android builder provides you with an easy way to change the layout from liner to constraint Layout.
