问题
I am trying to set the colour for the inactive tabs on BottomBar but can't find any method for doing so. I have set the background colour for the bar using this:
mBottomBar.getBar().setBackgroundColor(getResources().getColor(R.color.colorPrimary));
and would like to set the tabs to appear as white even when not in use, however don't seem to be able to do it: I am trying this method, but it doesn't work:
mBottomBar.mapColorForTab(0, "#ffffff");
on all the four tabs e.g. .mapColorForTab(1, "#ffffff"#); etc.

You can set the backgroundcolor of a specific tab by using the following line:
bottomBar.getTabAtPosition(0).setBackgroundColor(backgroundColorInt);
When you use this line multiple times for each tab, you can change the backgroundcolor of the whole tab.

Using the darkMode function solved this. Simply set in MainActivity.java like so:
mBottomBar.useDarkTheme();
