Responsive Layout In Android Using Constraint Layout

Create Responsive UI with Constraint Layout, this layout enables us to create a large and complex UI hierarchy in flat view, a major advantage of this layout is that we no longer required nested view group. It is similar to relative layout but more flexible than Relative Layout and you can design the layout with Android Studio Layout Editor very easily. So here is the tutorial to create the flat user interface using Constraint Layout.

1. Introduction

ConstraintLayout is available in API library and it is compatible with  API level 9 and upper version. Its design technique is well supported in Android Studio Layout Editor. Using Android Studio Layout Editor you can create the beautiful layout design by just using the drag and drop rather than writing the complete code in XML files. So, in simple word, we can say that we can create flat, flexible layout with this Layout.

2. Add ConstraintLayout dependency to project

For adding the constraintLayout to your project we need to flow the below-mentioned steps: –Install Constraint Layout Package

  1. Add the latest ConstraintLayout Library to your Android Studio
  2. Go to Tool> Android > SDK Manager
  3. Click on SDK Tool
  4. Under Support Repository select the “ConstraintLayout for Android” and “Solver for ConstraintLayout”
  5. Click on Apply and OK
  6. Click on Finish and then OK
Constrain Layout Install

3. Add Constraint Layout to in XML

For adding the constraint Layout to in your XML files add below XML code to your top-level view.

4. Adding Constraint to Constraint Layout View

Now click on design tab just after the text mode and start adding the other layout view inside Constraint Layout. Here in below screen shots as you can see that be have added two item one is text View and another one is the button.

In this, as you can see that Text View are connected to left side of the main Layout and similarly on top and button are connected with TextView from the left side and right side with the main layout. It is called constraint for adding the constraint to your view you have to click the view and then click on the anchor point and drag the anchor to other views to connect.
In Constraint Layout, every view must have two constraints one is horizontal and one is vertical. You can create the constraint only between two constraint handlers and an anchor point which have the same baseline.
For removing the constraint click on view and click on constraint handler as given in below screen shots as  I have clicked on TextView constraint handler.

5. Converting Liner Layout to Constraint Layout

For converting the Layout from Linear Layout to Constraint Layout we need to just open the layout XML file in design mode and then right click on the Linear Layout and click on convert view to Constraint Layout. It will automatically convert your Linear Layout to required format using which you can start designing your layout using just drag and drop for creating the decent looking layout for your mobile application.
