抽屉打开＆＃39;标题＆＃39;使用StackNavigator和DrawerNavigator

Question

我想使用React Navigation在标头中使用DrawerOpen。我显示错误＆＃34; undefined不是对象（评估this.props.navigation）＆＃34;。我使用的是StackNavigator和DrawerNavigator。

来源：https://reactnavigation.org/docs/navigators/drawer。

请帮忙。

header:{
    right: <Button onPress={() => 
    this.props.navigation.navigate('DrawerOpen')}
    title="Info" />
},

...
const SimpleApp = StackNavigator({
    Dashboard: { screen: DashboardScreen },
    Chat: { screen: ChatScreen },
});

const App = DrawerNavigator({
  Stack1:{screen:SimpleApp},
});

Answer 1

尝试使用：

navigationOptions: ({navigation}) => ({
    title:'title',
    headerLeft: <Button title="button" onPress={() => navigation.navigate('DrawerOpen')} />
})
