问题 Im currently working on a c# project that uses another .net library. This library does (amongst other things) parse a sequence into a tree. All items are of some type that inherits from the abstract class Sequence . I needed to alter the behaviour slightly and subclassed Sequence myself (lets call it MySequence ). After the tree was created, I could replace some tree nodes with objects of my own class. Now, a new version of the library was published, and a Copy function with the following

问题 I've seen answers suggesting just display:none on the :hover css. But that makes the div flicker when the mouse is moving. EDIT: Added jsfiddle 回答1: display:none will take the element out of the render tree, so it loses :hover state immediately, then reappears and gets :hover again, disappears, reappears, etc... What you need is: #elem { opacity:0; filter:alpha(opacity=0); } It will leave the place empty, so no flickering will appear. (Demo or yours updated) 回答2: Optionally with CSS3, but

问题 In previous xml layout, I have multiple view groups with few elements inside. Hide each view group will also hide all of its child elements. Since I wanted to have flat structure and tried ConstraintLayout . Cool I know how to chain element with spread to align properly. Since flat structure does not have wrapped LinearLayout , now i have 3 views to hide instead. I would like to know if there is alternative to achieve this. Without constraint layout <RelativeLayout.... .......... ..........
