问题
I have a floating action button and when the users taps on it I want a layout to be shown, animating from the bottom exactly like the Google Drive app (so not covering the whole screen). I read someone suggest the open source Umano's AndroidSlidingUpPanel but that is more similar to the Google Play Music app and I don't want that as I don't need the panel to be draggable/slidable.
What component should I use?
回答1:
This is the Bottom sheet component. Check out its specs: http://www.google.com/design/spec/components/bottom-sheets.html#bottom-sheets-specs
There are third libraries for the bottom sheet if you don't want to make it your self.
