具有两组堆栈导航器;
const SetOneScreens = () => (
<Stack.Navigator initialRouteName="AScreen">
<Stack.Screen name="AScreen" component={AScreen} />
<Stack.Screen name="BScreen" component={BScreen} />
</Stack.Navigator>
);
const SetTwoScreens = () => (
<Stack.Navigator initialRouteName="CScreen">
<Stack.Screen name="CScreen" component={CScreen} />
<Stack.Screen name="DScreen" component={DScreen} />
</Stack.Navigator>
);
哪个嵌套在Drawer导航器中
<NavigationContainer>
<Drawer.Navigator initialRouteName="SetOneScreens">
<Drawer.Screen name="SetOneScreens" component={SetOneScreens} />
<Drawer.Screen name="SetTwoScreens" component={SetTwoScreens} options={{swipeEnabled: false}} />
</Drawer.Navigator>
</NavigationContainer>
我想从BScreen
导航到DScreen
并重置堆栈(为了不让android中的硬件后退按钮回到BScreen
)
与嵌套情况一样,我们应该首先定义导航器名称;我该如何在重置操作中定义屏幕。
// For navigation
props.navigation.navigate('setTwoScreens',{screen:'DScreen'})
// For reset I can only navigate to initial screen
props.navigation.reset({index:0,routes:[{name:'setTwoScreens'}]})
我应该如何用reset
或navigation
处理CommonActions
答案 0 :(得分:5)
如react-navigation-v5的documentation所述,您需要使用reset-action调度CommonAction来清除应用程序的后向堆栈,这样当用户使用时,应用程序不会返回到上一个屏幕按下设备的硬件后退按钮,检查以下示例,
204
或者,如果您想在该StackNavigator中重置为特定的屏幕,您可以这样做:
import { CommonActions } from "@react-navigation/native";
props.navigation.dispatch({
...CommonActions.reset({
index: 0,
routes: [{ name: "AnotherStackNavigator" }]
})
});
