我是抽屉我使用了以下代码
主页代码:
@Html.TextBoxFor(model => model.DatemailedStart, new {id = "MailStartDate", placeholder = "MM/DD/YYYY", maxlength = "40", @class = "TextboxDates", @onblur = "isValidDate('MailStartDate');" })
function isValidDate(id) {
var dateString = $('#'+id+'').val();
}
我的主页的索引代码:
export default class HomeScreen extends Component {
render() {
return (
<Container>
<Header>
<Left/>
<Body>
...
</Body>
<Right style={{flex: 1}}>
<Button transparent onPress={() => {
this.props.navigation.openDrawer();
console.log('drawer');
}}>
<Icon name='menu'/>
</Button>
</Right>
</Header>
<Content>
</Content>
</Container>
);}
}
我的AboutUs页面的索引代码:
export default HomeScreenRouter = createDrawerNavigator({
Home: {screen: HomeScreen},
AboutUs: {screen: AboutUs},
},{
contentComponent: props => <SideBar {...props} />,
drawerPosition: "right",
initialRouteName: 'Home', });
关于我们代码:
export default (DrawNav = createStackNavigator
({ AboutUs: {screen: AboutUs},
},));
此代码在版本1中没有问题
但是在版本2中,返回按钮不起作用
当我使用手机的后退按钮时,应用关闭

这可能会对你有帮助。
//禁用设备返回按钮的页面代码
从'react-native'导入{BackHandler};
componentWillUnmount(){
BackHandler.removeEventListener('hardwareBackPress',
this.handleBackButton);
}
componentDidMount(){
BackHandler.addEventListener( 'hardwareBackPress',this.handleBackButton); }
handleBackButton(){
return true;
}
//设备返回按钮工作的页面代码和返回上一页的自定义后退按钮
从'react-native'导入{BackHandler};
componentWillMount(){
BackHandler.addEventListener('hardwareBackPress',
this.handleBackButtonClick);
}
componentWillUnmount(){
BackHandler.removeEventListener('hardwareBackPress',
this.handleBackButtonClick);
}
handleBackButtonClick(){
this.props.navigation.goBack(null);
return true;
}
