问题 I wanted to provide the SnackBar animation from top, instead of the regular behavior that displays the SnackBar from bottom. Is this easily hackable? 回答1: No it is not possible. The documentation states that They show a brief message at the bottom of the screen on mobile and lower left on larger devices. Snackbars appear above all other elements on screen and only one can be displayed at a time. You could use a third part library, like Crouton for instance 回答2: it is possible. check this

问题 Can't build project after adding compile 'com.android.support:design:24.2.0' Keeps giving the following errors: Seems like, the problem is with supporting vector drawables. Somewhere some attributes are added twice.

问题 OK, so I see PagerTabStrip has a bug - https://code.google.com/p/android/issues/detail?id=183127 Therefore, is TabLayout a better choice especially for now? Is there any downside to TabLayout? Some quirkiness where you might have to set all 3 items? I see TabLayout versus pagerTabStrip for convenience and functionality but that didn't really get answers... 来源： https://stackoverflow.com/questions/32770917/is-tablayout-supposed-to-replace-pagertabstrip-is-there-any-pro-to-pagertabst

问题 Hi. In the picture above you can see a back arrow and a (part of) title. I changed the title color using the attached .xml code. But I want to color the back arrow to white too.

问题 I am trying to animate a android.support.design.widget.FloatingActionButton that is pinned to my AppBarLayout. I can set it fine within the layout xml and it shows up fine. However i am doing a Shared Element Transition to this layout and the FAB is showing up before the view is set. I tried to set the visibility to GONE and INVISIBLE but they seem to be disregarded if the layout_anchor is set in the layout xml. Is there anyway around this? I would like the activity to load with the shared

问题 Today, it seems as though Android Nougat was released. Thus, I am more excited than ever to optimize my app for the new features like split-screen. I would like to push a version of my app that targets SDK version 24 so that users aren't notified that my app may not work in split-screen.
