Answer 1

This is my approach. It works for the version 5.x.x of react-navigation:

const BottomTab = createBottomTabNavigator();
const Tabs = props => (
   {
          // e.preventDefault(); // Use this to navigate somewhere else
          console.log("Foo tab bar button pressed")
        },
      }}
    />
  
);

For version 3.x.x and I hope for the 4th as well please use this one.

let Tabs = createBottomTabNavigator(
  {
    FooTab: Foo,
  },
  {
    initialRouteName: "FooTab",
    defaultNavigationOptions: ({ navigation }) => ({
      tabBarOnPress: ({ navigation, defaultHandler }) => {
        console.log('onPress:', navigation.state.routeName);
        defaultHandler()
      },
    }),
  }
);

For version 2.x.x please use navigationOptions instead of the defaultNavigationOptions.
