android - Floating Toolbar with Appcompat

Question

How to create a floating toolbar like the following image as proposed in the material design guidelines and in the Google Map application.

Answer 1

I've worked with the Toolbar before and all the comments from CommonsWare are absolutely correct.

The Toolbar widget (https://developer.android.com/reference/android/support/v7/widget/Toolbar.html) have absolutely nothing special or different than any other Viewgroup and does not behave differently than any other ViewGroup.

Put it inside a FrameLayout, put a layout_margin parameter on it, make the layout_width NOT match_parent and that's it.

Put it inside an LinearLayout with orientation=horizontal and you can use the layout_weight to control the size in percentage. Or just use plain dip if that suits your needs.
