gravity="fill_vertical" vs. layout_height="fill_parent" in Android
Why does gravity
offer a "fill_vertical" option? How i开发者_开发问答s this any different from setting layout_height
"fill_parent"? What if I choose a fixed layout_height
and "fill_vertical" for gravity? Won't this contradict?
I believe that using gravity="fill_vertical"
indicates that the View should take up as much space as possible vertically while still respecting other Views' height constraints. If you use layout_height="fill_parent"
, you're telling the View to take up the entire parent's height; this may result in a single View pushing other Views off the viewport.
