react-navigation

问题 I am new to react native and I am using react-navigation & react-navigation-material-bottom-tabs . All I want to do is curve the top-right corner and top-left corner of bottom tab bar. My Code: const screen1 = createMaterialBottomTabNavigator( { Home: { screen: HomeScreen, style : { backgroundColor: 'black' } }, About: AboutScreen, Scan: ScanScreen, Fav: AllScreen }, { initialRouteName: "Home", activeColor: 'red', inactiveColor: 'blue', barStyle: { borderWidth: 0.5, borderBottomWidth: 1,

问题 I installed the react-navigation package in react-native I have implemented tab navigation and one of them is implemented in webview format. My problem is that if I press the back physical button on Android, I go from the app itself to the previous tab, not back from the webview. I've already applied the back button for the webview on the internet, but I have not done that. I tried to display the onNavigationStateChange log when debugging, but it was not updated when url was moved after it

问题 I'm trying to change the color of the background in my react native app, from grey to white. I'm using react-navigation to make a TabNavigator after I render it. I tried to put this TabNavigator in a view and set backgroundColor but all screen became white. How can I solve this? index.js ... render() { return ( <View style={{ backgroundColor: '#FFFFFF'}}> <Tabs /> </View> ) } ... Tabs ... const Tabs = TabNavigator( { Home: { screen: HomeStack, navigationOptions: { title: 'Acasa', }, }, ...

问题 Are class components being abandoned? I see that in several libraries examples have function components as a priority. Especially React Navigation. Likewise, React itself with Hooks only makes them available for function components. The main question is: Why are function components being so prioritized? 回答1: No, i think Class Components won't be abandoned today. Maybe in future. They aren't lightweight as Functional Components can be, but i see a lot projects on community using Class

问题 I want to pass a prop to the screen. When I try that inline e.g (props) => <Comp {...props} {...customProps} /> I get a warning message, that I shouldn't parse functions to that component property. Okay. I thought I'll just create functions for every component which needs custom props. It is working, but is there a better solution? Here is my component: export default function Loading() { const [loggedIn, setLoggedIn] = React.useState(false); const Stack = createStackNavigator(); const
