How to add Chains feature of ConstraintLayout with Android Studio's 'Layout Editor'?

The chain style can be controlled by "chain" button right below the view:

Click on it few times to toggle between all 3 modes:

spread (the default one)

spread_inside

packed

Let's see some examples

centering views which are connected together using chain

1. drag and drop three buttons into the Android Studio's 'Layout Editor'

2. Select those buttons together by dragging mouse

3. Pack them vertically using the 'pack' button in 'Layout Editor'

4. Align them center horizontally using 'Align-Center horizontally' button

5. Align them center vertically using the 'Align-Center vertically' button

Here we used the pack option. similar to this, you can try spread and spread inside options of chain to see the difference. cheers :)
