我正在实现createBottomTabNavigator。我添加了一个tabBarIcon,我想使用我在全局样式文件中的const中定义的全局颜色,如下所示:
global.style.js
import { StyleSheet } from "react-native";
export const Colors = {
...
orange: "#F59200",
...
};
路由器.js
import React, { Component } from "react";
...
import { StackNavigator } from "react-navigation";
import { createBottomTabNavigator, BottomTabBar } from "react-navigation-tabs";
import Icon from "react-native-vector-icons/FontAwesome";
import Colors from "MyApp/app/config/global.style";
...
import HomeScreen from "../screens/HomeScreen";
...
export const Tabs = createBottomTabNavigator({
HomeScreen: {
screen: HomeScreen,
navigationOptions: () => ({
tabBarLabel: "My Home Screen",
tabBarIcon: ({ tintColor }) => (
// color={Colors.orange} does not work here
<Icon name="rocket" color={Colors.orange} size={24} />
)
})
},
...
我发现了一堆示例,这些示例显示了如何直接添加颜色,这些示例有效:
HomeScreen: {
screen: HomeScreen,
navigationOptions: () => ({
tabBarLabel: "My Home Screen",
tabBarIcon: ({ tintColor }) => (
<Icon name="rocket" color="#F59200" size={24} />
)
})
}
但我想知道是否有办法传递const Colors 值。
有任何想法吗?
提前致谢!
