从堆栈导航器中删除屏幕 [英] Remove screen from stack navigator

问题描述

我观察到后退按钮逻辑可以看到堆栈中的屏幕顺序.我在堆栈导航器中放置了一个抽屉导航器.

I’ve observed Back button logic works seeing the sequence of screens in the stack. I’ve a Drawer navigator placed inside stack navigator.

在堆栈顶部我有启动画面.在仪表板上，当我按下后退按钮时，我会进入闪屏.

On top of the stack I’ve Splash screen. On Dashboard when I press back button it takes me to splash screen.

如何在进入应用程序后从堆栈中删除启动画面，因此当我按下后退按钮仪表板时，它将退出应用程序而不是进入启动画面.

How can I remove splash screen from stack after entering in the app, So when I press back button Dashboard it will EXIT the app instead of taking to SPLASH SCREEN.

/* @flow */

import React from "react";
import { Platform, Text } from "react-native";
import { Root } from "native-base";
import { StackNavigator, DrawerNavigator} from "react-navigation";
import Register from "./components/Register";
import Available from "./components/Available";
import Splash from "./components/splash/";
import SideBar from "./components/sidebar";
import Discover from "./components/Discover/";
import Dashboard from "./components/Dashboard/";
import Contact from "./components/Contact"



const Drawer = DrawerNavigator(
  {
    Dashboard: { screen: Dashboard },
    Discover: { screen: Discover },
    Contact: { screen: Contact},
      },
  {
    navigationOptions: {
      gesturesEnabled: false,
    },
   initialRouteName: "Dashboard",
    contentOptions: {
      activeTintColor: "#e91e63"
    },
    drawerPosition: 'right',
    contentComponent: props => <SideBar {...props} />
  }
);


const AppNavigator = StackNavigator(
    {
      Splash: { screen: Splash },
      Drawer: { screen: Drawer },                           
      Available: { screen: Available },
        Register: { screen: Register },
    },
    {
       //  initialRouteName: "Splash",
         headerMode: "none",
    }
);

export default () =>
    <Root>
        <AppNavigator />
    </Root>;

推荐答案

一种解决方案是重置初始屏幕组件内的堆栈并将用户重定向到您喜欢的屏幕:

One solution would be to reset the stack inside the splash screen component and redirect the user to the screen that you prefer:

import { NavigationActions } from 'react-navigation'

const resetAction = NavigationActions.reset({
  index: 0,
  actions: [
    NavigationActions.navigate({ routeName: 'Drawer'})
  ]
})
this.props.navigation.dispatch(resetAction)

对于较新版本的 react-navigation :

For newer versions of react-navigation :

import { StackActions, NavigationActions } from 'react-navigation';

const resetAction = StackActions.reset({
  index: 0,
  actions: [NavigationActions.navigate({ routeName: 'Profile' })],
});
this.props.navigation.dispatch(resetAction);
