react-native-navigation 抽屉不改变屏幕

Question

我正在尝试遵循 react-native-navigation example 并构建一个小型测试应用程序。我无法让抽屉呈现所需的屏幕，而是总是转到主屏幕。在主屏幕上，我有一个按钮可以推动下一个屏幕，并且工作正常。感谢有人能提供帮助。

index.ios.js

import App from './App/App'

const app = new App();

App.js

import React, { Component } from 'react';
import {
 AppRegistry,
 StyleSheet,
 Text,
 View,
 Platform
} from 'react-native';

import { Navigation } from 'react-native-navigation';

// screen related book keeping
import { registerScreens } from './Screens/screens';
registerScreens();

const navigatorStyle= {
  navBarBackgroundColor: '#4dbce9',
  navBarTextColor: '#ffff00',
  navBarSubtitleTextColor: '#ff0000',
  navBarButtonColor: '#ffffff',
  statusBarTextColorScheme: 'light',
  statusBarTextColorScheme: 'light',
  tabBarBackgroundColor: '#4dbce9',
  tabBarButtonColor: '#ffffff',
  tabBarSelectedButtonColor: '#ffff00'
};

export default class App extends Component {



constructor(props){
   super(props)
   //load some data
   this.startApp();
}


startApp() {
   Navigation.startSingleScreenApp({
      screen: {
        screen: 'app.Home',
        title: 'Home',
        navigatorStyle
      },
      drawer: {
        left: {
          screen: 'app.Drawer'
        }
      }
    });

 }//end of startApp



}//end of App

Answer 1

this.props.navigator.popToRoot 函数存在问题。而是在主屏幕 (Home.js) 中使用 this.props.navigator.handleDeepLink({link: "link_name"}) 和一个 onNavigatorEvent(event) 处理程序来检查此 DeepLink

// handle a deep link
    if (event.type == 'DeepLink') {
      const parts = event.link;
      if (parts == 'Screen1') {
        this.onPressScreen1();
      }
    }
