With Constraintlayout no more match_parent?

Question

With the Constraintlayout feature, match_parent is no longer used?

Answer 1

Use/can use yes, because:

• Constraintlayout inherits from Viewgroup, which is the base class for all layout types.

• Any layout must have its dimensions defined.

• The value of the dimensions can be an integer value or one of the constants MATCH_PARENT / WRAP_CONTENT. They represent the value ffffffff and fffffffe respectively.

As with any Viewgroup to Constraintlayout, it may be necessary to indicate, instead of defining a fixed dimension, that it adapts its dimensions to those of its container or to those of its contents.
