项目工程是仿照喜马拉雅搭建
需要底部tab(5个)
- 首页
- 我听
- 播放
- 发现
- 账户
涉及导航器的使用
导航器分
1.堆栈式导航器
2.标签导航器
导航器的安装
yarn add @react-navigation/native
安装 react-navigation
相关依赖库
yarn add react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context @react-native-community/masked-view
- react-native-reanimated
- 动画库
- react-native-gesture-handler
- 手势库
- react-native-screens
- 提高性能
- react-native-safe-area-context
- 全面屏安全区库
- @react-native-community/masked-view
- 堆栈式导航器 依赖的库
在index.js 文件种导入依赖
import 'react-native-gesture-handler';
堆栈式导航器
- 安装
yarn add @react-navigation/stack
实例:完成首页往详情页的跳转
新增两个页面
- 首页
interface IProps {
navigation: RootStackNavigation;
}
/**
* 首页类
*/
class HomeStack extends React.Component<IProps> {
onPress = () => {
const {navigation} = this.props;
navigation.navigate("Detail", {id: 100});
}
render(){
return (
<View>
<Text>Home</Text>
<Button title="跳转到详情页" onPress={this.onPress}></Button>
</View>
);
}
}
// 导出首页类
export default HomeStack;
- 详情页
interface IProps {
route: RouteProp<RootStackParamList, 'Detail'>;
}
/**
* 详情页面
*/
class DetailStack extends React.Component<IProps> {
render(){
const {route} = this.props;
return(
<View>
<Text>Details</Text>
{/* 获取导航器跳转传参的值 */}
<Text>{route.params.id}</Text>
</View>
);
}
}
// 导出详情页面类
export default DetailStack;
- 实现堆栈式导航栏界面
export type RootStackParamList = {
Home: undefined;
Detail: {
id: number;
};
}
// 定义类型别名
export type RootStackNavigation = StackNavigationProp<RootStackParamList>;
// 创建堆栈 导航容器
let Stack = createStackNavigator<RootStackParamList>();
class NavigatorStack extends React.Component {
render() {
return (
<NavigationContainer>
{/* 堆栈导航器 */}
<Stack.Navigator
screenOptions={{ headerTitleAlign: 'center',
//左滑手势(Android设置)
gestureEnabled: true,
headerStyleInterpolator: HeaderStyleInterpolators.forUIKit,
cardStyleInterpolator: CardStyleInterpolators.forHorizontalIOS,
gestureDirection: 'horizontal',
headerStyle: {
...Platform.select({
android: {
elevation: 0,
borderBottomWidth: StyleSheet.hairlineWidth,
headerStatusBarHeight: StatusBar.currentHeight,
},
}),
},
}}
>
<Stack.Screen options={{ headerTitle: '首页' }} name='Home' component={HomeStack} />
<Stack.Screen options={{ headerTitle: '详情页' }} name='Detail' component={DetailStack} />
</Stack.Navigator>
</NavigationContainer>
);
}
}
// 导出 navigator
export default NavigatorStack;

标签导航器
- 安装
yarn add @react-navigation/bottom-tabs
- 添加几个tab类页面(Home,Listen,Found,Me)
interface IProps {
navigation: RootStackNavigation;
}
/**
* 首页类
*/
class Home extends React.Component<IProps> {
onPress = () => {
const {navigation} = this.props;
navigation.navigate("Detail", {id: 100});
}
render(){
return (
<View>
<Text>Home</Text>
<Button title="跳转到详情页" onPress={this.onPress}></Button>
</View>
);
}
}
// 导出首页类
export default Home;
- 添加BottomTabs 组件
export type BottomTabParamList = {
Home: undefined;
Listen: undefined;
Found: undefined;
Me: undefined;
}
type IProps = StackScreenProps<ParamListBase, string>;
// 底部Tab导航器组件
const Tab = createBottomTabNavigator<BottomTabParamList>();
function getHeaderTitle(route: any) {
//使用route.state的时候:官方提示用getFocusedRouteNameFromRoute
const routeName = getFocusedRouteNameFromRoute(route) ?? 'HomeTabs';
switch (routeName) {
case 'HomeTabs':
return '首页';
case 'Listen':
return '我听';
case 'Found':
return '发现';
case 'Me':
return '我的';
default:
return '首页';
}
}
class BottomTabs extends React.Component<IProps> {
componentDidUpdate() {
const { navigation, route } = this.props;
navigation.setOptions({
headerTitle: getHeaderTitle(route),
});
}
render() {
return (
// {/* 'tabBarOptions' is deprecated. Migrate the options to 'screenOptions' instead. */}
<Tab.Navigator screenOptions={{
tabBarActiveTintColor: '#ff5500',
// 隐藏导航栏
headerShown: false,
}}>
<Tab.Screen name="Home" component={Home} options={{tabBarLabel:'首页'}}/>
<Tab.Screen name="Listen" component={Listen} options={{tabBarLabel:'我听'}}/>
<Tab.Screen name="Found" component={Found} options={{tabBarLabel:'发现'}}/>
<Tab.Screen name="Me" component={Account} options={{tabBarLabel:'账户'}}/>
</Tab.Navigator>
);
}
}
//导出 底部tab组件
export default BottomTabs;
- 再外面嵌套堆栈导航器,这样 可以将详情页放到堆栈导航组件种,标签导航器也可以完成详情页的跳转
将前面堆栈式导航器里面的HomeStack页面容器,切换成BottomTabs标签导航器
{/* <Stack.Screen options={{ headerTitle: '首页' }} name='Home' component={HomeStack} /> */}
<Stack.Screen name='BottomTabs' component={BottomTabs} />
