I reworked my ActionBar on the ToolBar for this video tutorial, but I came across an unpleasant problem - elements from the list started to climb onto this ToolBar, this was not the case with the ActionBar. How can this problem be solved?

FrameLayoutplaces each newViewfrom the upper left edge of the screen, so overlapping elements occur. - pavlofff
