Is deprecated word the only difference between fill

 

I found that both fill_parent and match_parent means the same thing

  • fill_parent means that the view wants to be as big as its parent, minus the parent's padding, if any.
  • match_parent means that the view wants to be as big as its parent, minus the parent's padding, if any.

    • The only difference that I found is that fill_parent is deprecated starting from API Level 8 and is replaced by match_parent

    However, I didn't notice any difference between these two. If both are the same then, why is fill_parent deprecated. Can anyone explain any differences between these two except for the fact that one is deprecated and the other isn't?

    I have gone through http://developer.android.com/reference/android/view/ViewGroup.LayoutParams.html

    As you said they are exact the same. As Romain Guy said, they have changed the name because "fill_parent" was confusing for developers. As matter of the fact, "fill_parent" does not fill the remaining space (for that you use the weight attribute) but it takes as much space as its layout parent. That's why the new name is "match_parent" .

    According to Romain Guy in this video, these words mark the same behaviour. But many developers misunderstood what fill_parent meant, hence they came up with an alias.

    I have developed in Android long enough to also realize that there seems to be no difference except when you want to run on an older API. I would use fill_parent because I make all of my apps with minimum API 7. Also, on a side note, since Android is forward compatible this is the way to go.
