How to create a constraintlayout chain in Excel?
For example, figure 2 shows two views that both have a constraint to each other, thus creating a horizontal chain. Creating a chain is really easy, we can click and drag to select views or press ctrl and select views from Component Tree. And then right click on selected views in Editor Or Component Tree to apply constraints.
Which is an example of a horizontal chain?
A chain is a group of views that are linked to each other with bi-directional position constraints. For example, figure 2 shows two views that both have a constraint to each other, thus creating a horizontal chain.
How are views distributed in a constraintlayout chain?
Once chains are set, we can distribute the views horizontally or vertically with the following styles. Spread: The views are evenly distributed. E.g. Spread inside: The first and last view are affixed to the constraints on each end of the chain and the rest are evenly distributed. E.g.
What can we do with the help of constraintlayout?
With the help of ConstraintLayout , we can create complex and lengthy layouts with a flat view hierarchy. It means there is no need to nest multiple view groups ( LinearLayout or RelativeLayout ). It’s similar to RelativeLayout but much more flexible than RelativeLayout.
Where are the constraints at the end of the chain?
The first thing worth mentioning is that the two views at the ends of the chain (in this case the leftmost and rightmost views) already have constraints from their left & right edges respectively, to the parent. The creation of the chain simply defines the inter-relationships of the members of the chain.
How do you define a position in constraintlayout?
To define a view’s position in ConstraintLayout, you must add at least one horizontal and one vertical constraint for the view. Each constraint represents a connection or alignment to another view, the parent layout, or an invisible guideline.
