嵌套Drawer-StackNavigator,触发"DrawerOpen"不能使用React-Native

Question

我正在使用React Native和react-navigation制作应用程序.

[我的应用程序的层次结构]

*抽屉(APP)

ㄴStackNavigator

ㄴStackNavigator

我想要的是火 navigation.navigate('DrawerOpen');

我可以通过从左边缘拖动来显示我的抽屉,但不是通过按导航标题左侧的"菜单按钮"触发它.我花了这么多次来存档这个.请帮我.

const Nav = StackNavigator({
    mainnav_list:{
        screen: (props) => <TodoList {...props} dbCollectionName={props.screenProps.dbCollectionName}/>,
        navigationOptions:({navigation}) => ({
            headerLeft:(
                <TouchableOpacity onPress={() => {console.log(navigation); navigation.navigate('DrawerOpen');}}>
                    <Text style={{color:'white', marginLeft:15}}>Menu</Text>
                </TouchableOpacity>
            )
        })
    },
    mainnav_detail:{screen: TodoDetail}
}
,
{
    navigationOptions:(props) => ({
        title:props.screenProps.dbCollectionName,
        headerBackTitle:null,
        headerStyle:{backgroundColor:'#000'},
        headerTitleStyle:{color:'#fff'},
        headerTintColor:'#fff',
    })
})

const AppDrawer = DrawerNavigator(
{
    drawer1:{screen:() => <Nav screenProps={{dbCollectionName:'todos'}}/> },
    drawer2:{screen:() => <Nav screenProps={{dbCollectionName:'todos2'}}/> }
})

AppRegistry.registerComponent('TodosFS', () => AppDrawer);

在新版本的reactnavigation中打开,关闭或切换你DrawerNavigator只需使用以下内容即可

this.props.navigation.openDrawer();
this.props.navigation.closeDrawer();
this.props.navigation.toggleDrawer();
