React Native-标识活动屏幕。抽屉导航器
你能做的是
在您的上下文中,只有一个可以激活的屏幕,即约会屏幕。如果您想知道约会屏幕是否聚焦,则应检查DrawerContainer组件内的道具。它会给你activeItemKey
ie任命。
然后,你可以简单地检查DrawerComponent
,如果
this.props.activeItemKey === 'appointment' ? { color: '#000' } : { color: '#fff' }]}
您也可以通过activeTintColor
从DrawerNavigator道具如下所示,你可以找到其他DrawerNavigatorConfigs
在这里
const DrawerStack = DrawerNavigator({
appointment: {
screen: stackNav,
},
}, {
headerMode: 'none',
gesturesEnabled: false,
contentComponent: DrawerContainer,
contentOptions: {
activeTintColor: '#e91e63',
itemsContainerStyle: {
marginVertical: 0,
},
iconContainerStyle: {
opacity: 1
}
}
});
export default DrawerStack;
我在抽屉式导航器中使用堆栈导航器。我想做的是,我需要知道activeItem(活动屏幕),以便将其显示为活动状态。
StackNavigator
const stackNav = StackNavigator({
homeComponent: { screen: HomeScreen },serviceScreen: { screen: ServiceScreen },serviceDetailScreen: { screen: ServiceDetailScreen },selectVehicleScreen: { screen: SelectVehileScreen },addEditVehicle: { screen: AddVehicle },dateTimeScreen: { screen: DateTimeScreen },reviewScreen: { screen: ReviewScreen },notesScreen: { screen: NotesScreen },},{
headerMode: 'none'
});
抽屉导航器
const DrawerStack = DrawerNavigator({
appointment: {
screen: stackNav,{
headerMode: 'none',gesturesEnabled: false,contentComponent: DrawerContainer
});
export default DrawerStack;
