Android Studio sometimes using the deprecated ''fill_parent'

Question

I just downloaded Android Studio May 10, 2014 and started using the rich layout editor.

I noticed that when I would drag and drop a RelativeLayout, Android Studio would automatically use fill_parent for both the layout_width and the layout_height attributes.

Why does Android Studio not fill in the non-deprecated value, match_parent by default?

Answer 1

It has been filed as a bug but has not yet been confirmed. You can see the bug report here.

Answer 2

Because it's in alpha stage of development :)
