Android Studio Layout Editor ConstraintLayout: pack vs chain
问题 In the Android Studio Layout Editor I see the words "pack" and "chain" with respect to a ConstraintLayout . I know they both have something to do with multiple views being connected to each other in a line, but their difference is not clear to me. What is the difference between "pack" and "chain"? 回答1: Short answer A Chain is a group of views that are bound together in a vertical or horizontal line. Pack means that the views should be kept very closely together, ie, touch each other
