react-native - 如果使用react-native-vector-icons，则为react-navigation抽屉事件图标着色

Question

我有这个 react 抽屉导航:

我想将事件图标像标签一样设置为绿色。

我使用react-native-vector-icons 作为图标。

代码:

const AddMenuIcon = ({ navigate }) => (
  <View>
    <Icon
      name="plus"
      size={30}
      color="#FFF"
      onPress={() => navigate('DrawerOpen')}
    />
  </View>
)

const SearchMenuIcon = ({ navigate }) => (
  <Icon
    name="search"
    size={30}
    color="#FFF"
    onPress={() => navigate('DrawerOpen')}
  />
)

const LoginMenuIcon = ({ navigate }) => (
  <Icon
    name="user"
    size={30}
    style={{ fontWeight: '900' }}
    color="#FFF"
    onPress={() => navigate('DrawerOpen')}
  />
)

const Stack = {
  Login: {
    screen: Login,
    headerMode: 'none'
  },
  Search: {
    screen: Search,
    headerMode: 'none'
  },
  Add: {
    screen: Add,
    headerMode: 'none'
  }
}

const DrawerRoutes = {
  Login: {
    name: 'Login',
    screen: StackNavigator(Stack.Login, {
      headerMode: 'none'
    }),
    headerMode: 'none',
    navigationOptions: ({ navigation }) => ({
      drawerIcon: LoginMenuIcon(navigation)
    })
  },
  'Search Vegan': {
    name: 'Search',
    screen: StackNavigator(Stack.Search, {
      headerMode: 'none'
    }),
    headerMode: 'none',
    navigationOptions: ({ navigation }) => ({
      drawerIcon: SearchMenuIcon(navigation)
    })
  },
  'Add vegan': {
    name: 'Add',
    screen: StackNavigator(Stack.Add, {
      headerMode: 'none'
    }),
    headerMode: 'none',
    navigationOptions: ({ navigation }) => ({
      drawerIcon: AddMenuIcon(navigation)
    })
  }
}

const CustomDrawerContentComponent = props => (
  <SafeAreaView style={{ flex: 1, backgroundColor: '#3f3f3f', color: 'white' }}>
    <DrawerItems {...props} />
  </SafeAreaView>
)

const RootNavigator = StackNavigator(
  {
    Drawer: {
      name: 'Drawer',
      screen: DrawerNavigator(DrawerRoutes, {
        initialRouteName: 'Login',
        drawerPosition: 'left',
        contentComponent: CustomDrawerContentComponent,
        contentOptions: {
          activeTintColor: '#27a562',
          inactiveTintColor: 'white',
          activeBackgroundColor: '#3a3a3a',
        }
      }),
      headerMode: 'none',
      initialRouteName: 'Login'
    },
    initialRouteName: 'Login'
  },
  {
    headerMode: 'none',
    initialRouteName: 'Drawer'
  }
)

export default RootNavigator

如果使用react-native-vector-icons，有没有办法将事件图标的颜色与事件文本的颜色相同？ activeTintColor 不适用于图标。我们可以以编程方式检查是否处于事件状态吗？另一个奇怪的事情是 rgba 颜色在 CustomDrawerContentComponent 上不起作用，所以我无法使背景半透明，这很烦人。如果您也能提供帮助，那就太好了!

在react-navigation版本中:5.x

使用颜色而不是tintColor providing-a-custom-drawercontent

    <Drawer.Screen name="settingscreen" component={Settings}
            options={{
                drawerLabel: "Settings",
                drawerIcon: ({ color }) => <MaterialCommunityIcons name="settings" size={24} style={[styles.icon, { color: color }]} />
            }}
        />
