我有一个带有react-navigation的应用程序,我想在其上绘制导航栏。我的app.js看起来像这样:
export default class App extends React.Component {
render() {
return (
<Provider store={store}>
<StatusBar barStyle='dark-content'></StatusBar>
<Navigation />
</Provider>
)
}
}
...
const AppNavigator = createStackNavigator({
Home: HomeView,
Detail: DetailView
},
let Navigation = createAppContainer(AppNavigator)
在作为根组件的HomeView中,我的渲染方法如下:
render() {
return (
<View style={{ flex: 1, backgroundColor: colors.backgroundColor }}>
{isModalVisible && <View style={styles.overlay}>
... Modal content
</View>}
... Other views
</View>
)
}
overlay: {
position: 'absolute',
zIndex: 1,
top: 0,
left: 0,
width: Dimensions.get('screen').width,
bottom: 0,
backgroundColor: '#000000A0',
},
我的问题是,模态视图不会在导航栏上渲染,即该栏不在叠加层之下。我不能使用内置模态或react-native-modal,可以通过导航栏呈现常规视图吗?
答案 0 :(得分:0)
我最终从与导航项处于同一级别的根容器中显示了模式视图。
RootContainer.js:
{"AAPL":[{"t":1590090900,"o":317.06,"h":317.32,"l":317,"c":317.07,"v":5654},{"t":1590090960,"o":317.07,"h":317.07,"l":316.77,"c":316.78,"v":6608},{"t":1590091020,"o":316.73,"h":316.77,"l":316.585,"c":316.71,"v":12578},{"t":1590091080,"o":316.855,"h":317.17,"l":316.855,"c":317.04,"v":8184},{"t":1590091140,"o":317,"h":317.45,"l":316.77,"c":317.06,"v":21572}]}
并且App呈现RootContainer:
render() {
return (
<View style={{ flex: 1 }}>
<StatusBar barStyle='dark-content'></StatusBar>
<Navigation />
{isModalVisible && <View style={styles.overlay}>
... Modal content
</View> } />}
</View>
)
}
...
const AppNavigator = createStackNavigator({
Home: HomeView,
Detail: DetailView
},
let Navigation = createAppContainer(AppNavigator)
这不是最佳的解决方案,因为您一直将组件中的数据一直传递到根。但这是反应导航的已知缺点之一。您可以在https://github.com/react-navigation/react-navigation/issues/363
上看到一些想法和讨论。对于那些使用redux的用户,请像我这样使用:您必须嵌套一个级别(不是嵌套屏幕或来自App的模态,而是RootContainer),因为redux不允许在App中创建存储并同时使用connect。参考:https://stackoverflow.com/a/41892948/837244
