我有 3 个选项卡 Tab1、Tab2 和 Tab3。如何从任何选项卡动态更改此选项卡标题。
以下是我的代码..
const TabNav = createBottomTabNavigator(
{
TabName1: {
header: null,
screen: StackNav1,
navigationOptions: ({ navigation }) => ({
title: 'Tab1',
header: null,
tabBarIcon: ({ tintColor }) => {
return;
}
})
},
TabName2: {
header: null,
screen: StackNav2,
navigationOptions: ({ navigation }) => ({
title: 'Tab2'
})
},
TabName3: {
screen: StackNav3,
navigationOptions: ({ navigation }) => ({
header: null,
title: 'Tab3'
})
}
},
{
initialRouteName: "TabName1",
tabBarPosition: "bottom",
headerMode: "none",
swipeEnabled: false,
animationEnabled: false,
lazy: true,
removeClippedSubviews: true,
order: ["TabName1", "TabName2", "TabName3"],
backBehavior: "initialRoute",
}
);
请帮助我如何动态更改标签标题。
谢谢,
