DrawerNavigator
Used to easily set up a screen with a drawer navigation.
class MyHomeScreen extends React.Component {
static navigationOptions = {
drawer: () => ({
label: 'Home',
icon: ({ tintColor }) => (
<Image
source={require('./chats-icon.png')}
style={[styles.icon, {tintColor: tintColor}]}
/>
),
}),
}
render() {
return (
<Button
onPress={() => this.props.navigation.navigate('Notifications')}
title="Go to notifications"
/>
);
}
}
class MyNotificationsScreen extends React.Component {
static navigationOptions = {
drawer: () => ({
label: 'Notifications',
icon: ({ tintColor }) => (
<Image
source={require('./notif-icon.png')}
style={[styles.tabIcon, {tintColor: tintColor}]}
/>
),
}),
}
render() {
return (
<Button
onPress={() => this.props.navigation.goBack()}
title="Go back home"
/>
);
}
}
const styles = StyleSheet.create({
icon: {
width: 24,
height: 24,
},
});
const MyApp = DrawerNavigator({
Home: {
screen: MyHomeScreen,
},
Notifications: {
screen: MyNotificationsScreen,
},
});
To open and close drawer, navigate to 'DrawerOpen' and 'DrawerClose' respectively.
this.props.navigation.navigate('DrawerOpen'); // open drawer
this.props.navigation.navigate('DrawerClose'); // close drawer
API Definition
DrawerNavigator(RouteConfigs, DrawerNavigatorConfig)
RouteConfigs
The route configs object is a mapping from route name to a route config, which tells the navigator what to present for that route, see example from StackNavigator.
DrawerNavigatorConfig
drawerWidth- Width of the drawerdrawerPosition- Options areleftorright. Default isleftposition.contentComponent- Component used to render the content of the drawer, for example, navigation items. Receives thenavigationprop for the drawer. Defaults toDrawerView.Items. For more information, see below.contentOptions- Configure the drawer content, see below.
Example:
Default the DrawerView isn't scrollable.
To achieve a scrollable View, you have to use the contentComponent to customize the container,
as you can see in the example below.
{
drawerWidth: 200,
drawerPosition: 'right',
contentComponent: props => <ScrollView><DrawerView.Items {...props} /></ScrollView>
}
Several options get passed to the underlying router to modify navigation logic:
initialRouteName- The routeName for the initial route.order- Array of routeNames which defines the order of the drawer items.paths- Provide a mapping of routeName to path config, which overrides the paths set in the routeConfigs.backBehavior- Should the back button cause switch to the initial route? If yes, set toinitialRoute, otherwisenone. Defaults toinitialRoutebehavior.
Providing a custom contentComponent
You can easily override the default component used by react-navigation:
const CustomDrawerContentComponent = (props) => (
<View style={style.container}>
<DrawerView.Items {...props} />
</View>
);
const styles = StyleSheet.create({
container : {
flex : 1,
},
});
contentOptions for DrawerView.Items
activeTintColor- label and icon color of the active labelactiveBackgroundColor- background color of the active labelinactiveTintColor- label and icon color of the inactive labelinactiveBackgroundColor- background color of the inactive labelstyle- style object for the content sectionlabelStyle- style object to overwriteTextstyle inside content section, when your label is a string
Example:
contentOptions: {
activeTintColor: '#e91e63',
style: {
marginVertical: 0,
}
}
Screen Navigation Options
Usually you define static navigationOptions on your screen component. For example:
class ProfileScreen extends React.Component {
static navigationOptions = {
title: ({ state }) => `${state.params.name}'s Profile!`,
drawer: {
icon: (
<Image src={require('./my-icon.png')} />
),
},
};
...
All navigationOptions for the DrawerNavigator:
title- a title (string) of the scenedrawer- a config object for the drawer:label- String, React Element or a function that given{ focused: boolean, tintColor: string }returns a React.Element, to display in drawer sidebar. When undefined, scenetitleis usedicon- React Element or a function, that given{ focused: boolean, tintColor: string }returns a React.Element, to display in drawer sidebar
Navigator Props
The navigator component created by DrawerNavigator(...) takes the following props:
screenProps- Pass down extra options to child screens, for example:
const DrawerNav = DrawerNavigator({
// config
});
<DrawerNav
screenProps={/* this prop will get passed to the screen components as this.props.screenProps */}
/>
