Android Difference between View.getLeft() vs View.getScrollX() -


what difference between view.getleft() vs view.getscrollx() ? please don't copy , paste definition documentation, because below

getscrollx()

return scrolled left position of view.

getleft()

left position of view relative parent

i think 2 values should same, sample program of mine, if view.scrollby(20, 0) see getscrollx() return 20 , view moved right, getleft() remains zero

i confused, because if visually view being scrolled right 20px, left position should updated well, still 0

obviously can't same, otherwise there no need have 2 different methods return same result

please help

getleft() returns views location relative parent. how has scrolled not impact @ all. scrolling impacts contents of view, not location.

a quote android documentation regarding getleft():

for instance, when getleft() returns 20, means view located 20 pixels  right of left edge of direct parent.

getscrollx(), on other hand, lets know how content in view has moved.

view.scrollby(20,0) affects content in view (like subviews of view) , doesn't move view relative view's parent.
