I want to use bottom navigation bar in my existing android app but the problem is all screen are activity ,is it possible to load activity without hiding the bottom navigati
With Activity, you have to declare and init that BottomBar each time you load that activity.
With your problem, my answer is NO.
Btw, you can use Fragment which helps you solve this pretty good.
Time to learn something new, bro.
EDIT
You bring Fragment inside only 1 Activity. And let BottomBar inside Activity while all others view and data set inside Fragment.
Just try it!
