match_parent, which means that the view wants to be as big as its parent (minus padding).

wrap_content, which means that the view wants to be just big enough to enclose its content (plus padding)

In "Match parent" textView content, we can see it's layout width spread out of it's parent whole length.

But we can see in "Wrap Content" textView content, it's layout width wrapped in of it's content(Wrap Content) length.
