This code works for me: public static boolean isVisible(final View view) { if (view == null) { return false; } if (!view.isShown()) { return false; } final Rect actualPosition = new Rect(); view.getGlobalVisibleRect(actualPosition); final Rect screen = new Rect(0, 0, getScreenWidth(), getScreenHeight()); return actualPosition.intersect(screen); }
Calculate the amount of px an element (height) is in viewport Fiddle demo This tiny function will return the amount of px an element is visible in the (vertical) Viewport: function inViewport($el) { var elH = $el.outerHeight(), H = $(window).height(), r = $el[0].getBoundingClientRect(), t=r.top, b=r.bottom; return Math.max(0, t>0? Math.min(elH, H-t) : Math.min(b, H)); } Use … Read more
You can get the rect of a cell with rectForRowAtIndexPath: method and compare it with tableview’s bounds rect using CGRectContainsRect function. Note that this will not instantiate the cell if it is not visible, and thus will be rather fast. Swift let cellRect = tableView.rectForRowAtIndexPath(indexPath) let completelyVisible = tableView.bounds.contains(cellRect) Obj-C CGRect cellRect = [tableView rectForRowAtIndexPath:indexPath]; … Read more
