ActionMenuView, SearchView

ActionMenuView	ActionMenuView is a presentation of a series of menu options as a View.
SearchView	A widget that provides a user interface for the user to enter a search query and submit a request to a search provider.

---

A Layout that arranges its children in a single column or a single row. The direction of the row can be set by calling setOrientation(). You can also specify gravity, which specifies the alignment of all the child elements by calling setGravity() or specify that specific children grow to fill up any remaining space in the layout by setting the weight member of LinearLayoutCompat.LayoutParams. The default orientation is horizontal.

See the Linear Layout guide.

Also see LinearLayoutCompat.LayoutParams for layout attributes
