React Native Navigation GoBack无法正常工作

Question

即时通讯使用反应导航3，也使用

this.props.navigation.navigate(item.navigationPath)

浏览页面

问题是，当我单击导航栏中的按钮后退时，它不后退。我希望它后退1步，但它什么也没做

这是后面的部分

    class NavigationBack extends Component  {
    toggleDrawer = () => {
    this.props.navigation.goBack()
  };
    render() {
    return (
      <View style={{ flexDirection: 'row' }}>
        <TouchableOpacity onPress={this.toggleDrawer.bind(this)}>
          <Image
            source={require('./image/drawer.png')}
            style={{ width: 25, height: 25, marginLeft: 5 }}
          />
        </TouchableOpacity>
      </View>
    );
  }
}

另外当我在主页->类别->单类别中并且我按下硬件后退按钮时，它将我带到家庭而不是类别

我尝试了您的代码并进行了一些修改。 您可以检查此代码吗？ 这是您需要的吗？

/*Example of Navigation Drawer with Sectioned Menu*/
import React, { Component } from 'react';
import {
  StyleSheet,
  Platform,
  View,

//Import required react-navigation component
