Is there an official API for centered title on Toolbar like on popular Android apps, in the new material design?

Answer 1

How about textAlignment="center"? a RelativeLayout does the trick, when AppCompatTextView has set layout_width="match_parent"; for example:

the down-side is, that when showing several menu-items as action buttons - or when displaying extraordinary long strings as title, the title may overlap them - but when only showing one or two action buttons in combination with a title that fits the visually available width, this works just fine - that's because menu config ifRoom would always apply, because there is room. else one could only measure, which side of the toolbar has the most wide items' container - and then adjust the width on the other side's items' container. scaling the font-size depending on the available room might also be an option, to make it fit dynamically.
