What is the difference between match_parent and fill_parent?

  • 772

Before the arrival of the match_parentI used a lot fill_parentto define the total width of the view. I didn't quite understand why the Android development team went on to substitute one for the other. What is the difference between the match_parentand the fill_parent? Why fill_parentwas he replaced by match_parent?

  1. Best Answer

    There is no marked difference between the two, both are used to define the size of the component (View) to be as large as the parent. It was only renamed from the API 8 fill_parent by match_parent.

    Why was the fill_parent replaced by match_parent?

    The team at Androidfound that the developers were misunderstanding FILL_PARENTthat a Viewcould fill the remaining space of the parent element. That is why the constant was renamed MATCH_PARENTto clarify its use.
