我几乎从TabNavigator文档中获取了示例代码,而图标/图像根本没有出现在iOS或
Android上.即使标签覆盖似乎也没有生效.我究竟做错了什么?
这是我一直在使用的文档的链接:
https://reactnavigation.org/docs/navigators/tab
这是我的代码:
class MyHomeScreen extends React.Component { static navigationOptions = { tabBarLabel: 'Not displayed',// Note: By default the icon is only shown on iOS. Search the showIcon option below. tabBarIcon: ({ tintColor }) => ( <Image source={require('./chats-icon.png')} style={[styles.icon,{tintColor: tintColor}]} /> ),}; render() { return ( <Button onPress={() => this.props.navigation.navigate('Notifications')} title="Go to notifications" /> ); } } class MyNotificationsScreen extends React.Component { static navigationOptions = { tabBarLabel: 'Notifications',tabBarIcon: ({ tintColor }) => ( <Image source={require('./notif-icon.png')} style={[styles.icon,}; render() { return ( <Button onPress={() => this.props.navigation.goBack()} title="Go back home" /> ); } } const styles = StyleSheet.create({ icon: { width: 26,height: 26,},}); const MyApp = TabNavigator({ Displayed: { screen: MyHomeScreen,Notifications: { screen: MyNotificationsScreen,{ tabBarOptions: { activeTintColor: '#e91e63',});
好吧,在我想把脸撞到键盘上后,我终于想通了.
标题和标签栏图标实际上是与文档内部不同的结构.
const MyApp = TabNavigator({ Displayed: { screen: MyHomeScreen,navigationOptions: { title: 'Favorites',tabBar: { icon: ({tintColor}) => (<Image source={require('./chats-icon.png')} style={{width: 26,tintColor: tintColor}} />) },...
要么
class MyHomeScreen extends React.Component { static navigationOptions = { title: 'Foo Bar',tabBar: { icon: ({ tintColor }) => ( <Image source={require('./chats-icon.png')} style={{width: 26,tintColor: tintColor}} /> ),} }; ...
