How to "screw" layout with buttons on top of Google Map?

Question

Java

Good day!
I really need help! I am making an App with a Google map (everything seems to be clear with it) and I would like to "screw" a small slide fragment with two buttons on top of the map, which will occupy 25% of the screen (its upper part).
What are the best elements to implement this idea?

Answer 1

RelativeLayout
map fragment /
and further child elements with parameters, for example:
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
/RelativeLayot
for example the text of a view with such parameters will be displayed in the upper left corner.
Z.Y. XML without formatting because the site removes the syntax.

Answer 2

Use FrameLayout

Answer 3

no matter which one you like best and best suits your task
