我正在尝试在我的 jhipster ignite 应用程序中添加底部标签栏,该应用程序使用 react-native-navigation v2。
屏幕注册如下:
Navigation.registerComponentWithRedux(LAUNCH_SCREEN, () => LaunchScreen, Provider, store)
例如:
export const LAUNCH_SCREEN = 'nav.LaunchScreen'
这是完整的导航:
export const topBar = {
title: {
text: 'MDNGHT',
color: Colors.snow
},
leftButtons: [
{
id: 'menuButton',
icon: Images.menuIcon,
testID: 'menuButton',
color: Colors.snow
}
]
}
export const launchScreenComponent = {
component: {
id: 'id.launch',
name: LAUNCH_SCREEN,
options: {
topBar: topBar,
bottomTab: {
fontSize: 12,
text: 'HOME'
}
}
}}
export const eventsScreenComponent = {
component: {
id: 'id.events',
name: EVENTS_SCREEN,
options: {
topBar: topBar,
bottomTab: {
fontSize: 12,
text: 'EVENTS'
}
}
}
}
export const bottomTabs = {
id: 'bottomTabs',
children: [
{
stack: {
children: [
launchScreenComponent
]
}
},
{
stack: {
children: [
eventsScreenComponent
]
}
}
],
options: {
bottomTabs: {
activeTintColor: 'red',
inactiveTintColor: 'grey',
backgroundColor: '#121212',
borderTopWidth: 0,
shadowOffset: {width: 5, height: 3},
shadowColor: 'black',
shadowOpacity: 0.5,
elevation: 5
}
}
}
export const appStack = {
root: {
sideMenu: {
left: {
component: {
name: DRAWER_CONTENT
}
},
center: {
bottomTabs: bottomTabs
}
}
}
}
Navigation.events().registerAppLaunchedListener(() => {
Navigation.setDefaultOptions({
topBar: {
topBar: {
title: {
color: Colors.snow
}
},
backButton: {
showTitle: false,
testID: 'backButton',
icon: Images.chevronLeftIcon,
color: Colors.snow,
iconColor: Colors.snow
},
background: {
color: Colors.background
}
},
sideMenu: {
left: {
enabled: false
}
}
})
Navigation.setRoot(appStack)
// handle app state and deep links
AppState.addEventListener('change', handleAppStateChange)
Linking.addEventListener('url', handleOpenURL)
})
我没有收到任何错误消息,我的应用程序只是在启动后停止。当我放:
stack: {
id: 'center',
children: [launchScreenComponent]
}
代替bottomTabs:appStack中的bottomTabs,应用程序工作(但没有底部标签栏)
