I want to ask: If I set the Navigationbar Translucent, and then I set color to it. when someday I use the Third Library:Floating Aciton Button, the FAB is sheltered by the Navigationbar , so what I can do for this problem?? I want the fab floating above the Navigationbar and the Navigationbar Is Colorful...
