RN v 0.46.1プロジェクトで反応ナビゲーションを使用していますアクティブなタブの色を変更するにはどうすればいいですか? (タブはカスタムです)
私はreact-navigationのexampleディレクトリからcustomTabsを使用しました。
アクティブなときにタブの色を変更したいと思います。
私は、navigationOptionsを使用して渡すことを試みましたが、成功しませんでした。
また、上部にタブが表示されています。下部に表示します。
import React, { Component } from "react";
import { AppRegistry, Button,
Platform,
ScrollView,
StyleSheet,
Text,
TouchableOpacity,
View } from "react-native";
import { createNavigator,
createNavigationContainer,
TabRouter,
addNavigationHelpers } from 'react-navigation'
import Chats from './Chats'
import Contacts from './Contacts'
const MyNavScreen = ({ navigation, banner }) => (
<ScrollView>
<Text>banner</Text>
<Button
onPress={() => {
navigation.goBack(null);
}}
title="Go back"
/>
</ScrollView>
);
const MySettingsScreen = ({ navigation }) => (
<MyNavScreen banner="Settings Screen" navigation={navigation} />
);
const CustomTabBar = ({ navigation }) => {
const { routes } = navigation.state;
return (
<View style={styles.tabContainer}>
{routes.map(route => (
<TouchableOpacity
onPress={() => navigation.navigate(route.routeName)}
style={styles.tab}
key={route.routeName}
>
<Text>{route.routeName}</Text>
</TouchableOpacity>
))}
</View>
);
};
const CustomTabView = ({ router, navigation }) => {
const { routes, index } = navigation.state;
const ActiveScreen = router.getComponentForState(navigation.state);
const routeNav = addNavigationHelpers({
...navigation,
state: routes[index],
});
const routeOptions = router.getScreenOptions(routeNav, 'tabBar');
console.log(routeOptions.headerTintColor);
return (
<View style={styles.container}>
<CustomTabBar navigation={navigation} />
<ActiveScreen
navigation={addNavigationHelpers({
...navigation,
state: routes[index],
})}
/>
</View>
);
};
const CustomTabRouter = TabRouter(
{
Friends: {
screen: Chats,
path: '',
},
Status: {
screen: Contacts,
path: 'notifications',
},
Other: {
screen: MySettingsScreen,
path: 'settings',
},
},
{
initialRouteName: 'Friends',
},
);
const CustomTabs = createNavigationContainer(
createNavigator(CustomTabRouter)(CustomTabView)
);
const styles = StyleSheet.create({
container: {
marginTop: Platform.OS === 'ios' ? 20 : 0,
},
tabContainer: {
flexDirection: 'row',
height: 48,
},
tab: {
flex: 1,
alignItems: 'center',
justifyContent: 'center',
margin: 4,
borderWidth: 1,
borderColor: '#ddd',
borderRadius: 4,
backgroundColor:'white'
},
});
export default CustomTabs;
AppRegistry.registerComponent('awsm',() => CustomTabs);
アクティブなタブの 'routeName'を取得できますか? –
