Differences between "fill_parent" and "wrap_content" [duplicate]

Question

I'm new to this, I would say what is the difference between width = "fill_parent" and width = "wrap_content"?

Answer 1

fill_parent will make the width or height of the element to be as large as the parent element, in other words, the container.

wrap_content will make the width or height be as large as needed to contain the elements within it.
