Sending props with Tabs from 'react-native-tabs' - react-native

I am using Tabs from 'react-native-tabs' to navigate from one screen to another, how can I send props to the individual components of the tabs?
I am using the following code to display tabs,
import Tabs from 'react-native-tabs';
<Tabs
selected={page}
style={styles.tabbar}
selectedStyle={{color:'black'}}
onSelect={el=>this.setState({page:el.props.name})}
>
<Text style={styles.tabbarText} name={Contact}>Contact</Text>
<Text style={styles.tabbarText} name={Messages}>Messages</Text>
<Text style={styles.tabbarText} name={Profile}>Profile</Text>
</Tabs>

I figured it out, you can mention the props in the
<this.state.page style={styles.pageContainer} navigator={this.props.navigator}/>
line of code.
The entire render() function is here,
render() {
const { page } = this.state;
return (
<View style={styles.container}>
<this.state.page style={styles.pageContainer} navigator={this.props.navigator}/>
<Tabs
selected={page}
style={styles.tabbar}
selectedStyle={{color:'black'}}
onSelect={el=>this.setState({page:el.props.name})}
>
<Text style={styles.tabbarText} name={Contact}>Contact</Text>
<Text style={styles.tabbarText} name={Messages}>Messages</Text>
<Text style={styles.tabbarText} name={Profile}>Profile</Text>
</Tabs>
</View>
);
}

It may help you.
class Home2Screen extends React.Component {
render() {
console.log(this.props.navigation.state);
return (
<View>
</View>
);
}
}
class SettingsScreen extends React.Component {
render() {
console.log(this.props.navigation.state);
return (
<View>
</View>
);
}
}
const tab = TabNavigator(
{
Home2: { screen: Home2Screen },
Settings: { screen: SettingsScreen },
},
{}
);
class HomeScreen extends React.Component {
goToTab() {
this.props.navigation.navigate('Tab', {
carData: {some: 'data'},
});
}
render() {
return (
<View>
<Button onPress={() => { this.goToTab() }} />
</View>
);
}
}
const HomeNavigator = StackNavigator({
Home: {
screen: HomeScreen,
},
Tab: {
screen: tab,
},
}, {
mode: Platform.OS === 'ios' ? 'modal' : 'card',
});
const HomeNavigationDrawer = DrawerNavigator({
HomePage: {
screen: HomeNavigator,
},
}, {});
export default HomeNavigationDrawer;

How to pass a function as a prop in React-Native

I'm currently working on an app in React-Native and it includes DrawerNavigation, SwitchNavigation and AppContainer. There is a method at header.js that i need to use in order to make the drawer functionable (toggleDrawer())
I've tried passing the function at the DrawerNavigator but it didnt work.
export default class Header extends React.Component {
render() {
return (
<View style={styles.container}>
<TouchableOpacity
onPress={() => {
this.props.navigation.toggleDrawer();
}}
>
<Image
source={require("/Users/Rron/AnketaApp/assets/hamburger-
icon.jpg")}
style={styles.imageStyle}
/>
</TouchableOpacity>
</View>
);
}
}
});
export default class HomeScreen extends React.Component {
static navigationOptions = ({ navigation }) => {
let drawerLabel = "Home";
return { drawerLabel };
};
render() {
return (
<View style={styles.container}>
<Header {...this.props}/>
<ScrollView>
<Content />
</ScrollView>
</View>
);
}
}
export default class DrawerNavigator extends React.Component {
render() {
return <AppContainer />;
}
}
const AppDrawerNavigator = createDrawerNavigator(
{
Home: {
screen: HomeScreen
},
Anketa: {
screen: AnketaScreen
}
}
);
const AppContainer = createAppContainer(
createSwitchNavigator({
Introduction: {
screen: IntroductionScreen
},
Drawer: {
screen: AppDrawerNavigator``
}
})
);
The error says
this.props.navigation.toggleDrawer is not a function and its not
defined.
What you can do is import { DrawerActions } from 'react-navigation-drawer' and use it as it says in the docs.
this.props.navigation.dispatch(DrawerActions.toggleDrawer());
Also make sure that you components are inside the navigation.

React Native navigate using Touchable Opacity

I want to make the Play button to navigate to the play screen. I created a an app class as the main file. Then in my cluster1, I am able to press a play button. But I don't know how to navigate the play button to the play class screen.
This is my App Class
export default class App extends Component {
render() {
return (
<View style={styles.container}>
<AppNavigator/>
</View>
);}}
const AppNavigator = StackNavigator({
Cluster1: {
screen: Cluster1,
},
Play: {
screen: Play,
},
});
This is my Cluster1 Class
export default class Cluster1 extends Component{
static navigationOptions = {
title: 'Choose the Mood Cluster to listen',};
render(){
return(
<View>
<SectionList
renderItem={({item,index})=>{
return(
<SectionListItem item={item} index={index}> </SectionListItem>);}}
renderSectionHeader={({ section }) => {
return (<SectionHeader section={section} />);}}
sections={ClusterData}
keyExtractor={(item, index) => item.name}>
</SectionList>
</View>
);
}}
class SectionHeader extends Component {
render() {
const AppNavigator = StackNavigator({
Cluster1: { screen: Cluster1},
Play: { screen: Play},
});
return (
<View style={styles.header}>
<Text style={styles.headertext}>
{this.props.section.title}
</Text>
<TouchableOpacity onPress={() => {this.props.navigation.navigate('Play')}}> Play</TouchableOpacity>
</View>
);
}}
This is my Play class
export default class Play extends Component{
static navigationOptions = {
headerMode: 'none', };
render(){
return(
<View style={styles.container}>
<Text>Play Screen</Text>
</View>
);
}{
What do i add in for my touchableopacity statement?
You can use like this. Use navigation option to navigate the component
const AppNavigator = StackNavigator({
Cluster1: { screen: Cluster1},
Play: { screen: Play},
});
<TouchableOpacity onPress={() => {this.props.navigation.navigate('Play')}}> Play</TouchableOpacity>

Open Drawer by clicking in header of containing StackNavigator

This is the component which contains my Drawer
export default class StackInView extends React.Component {
render() {
const Stack = StackNavigator({
DrawerStack: { screen: DrawerInView }
}, {
headerMode: 'float',
});
return (
<View style={{ flex: 1 }}>
<Stack />
</View>
);
}
}
The following is where I define my button. I want to define the button in navigationOptions of the screen, because the button should only appear on the screen with the drawer. But clicking the button doesn't work can you help me pls?
... imports ...
export default class DrawerInView extends React.Component {
static navigationOptions = {
title: "Yeah?",
headerRight: <Button title="Menu" onPress={() => {NavigationActions.navigate("DrawerOpen")}}/>
}
constructor(props) {
super(props);
}
render() {
const Drawer = DrawerNavigator({
"one": {
screen: () => {
return (<TabsInView select="something" />)
},
},
"two": {
screen: () => {
return (<TabsInView select="something else" />)
},
}
})
return (
<View style={{ flex: 1 }}>
<Drawer />
</View>
);
}
}
You can open DrawerNavigation on button click like this.
<Button title="Menu" onPress ={ ( ) => this.props.navigation.openDrawer()} />
Don't put Stack into View. It's hard to understand and you break all props.
And the reason it doesn't work is that navigationOptions in second code is not for the drawer but for the StackNavigator in the first code. So it can't execute drawer's navigation.navigate("DrawerOpen") because it's StackNavigator's.
And I highly recommend you to change your app's hierarchy. It's really hard that child Drawer passes its navigation to parent Stack's right button.
Then, it would look like this.
const MyStack = StackNavigator({
Tabs:{ screen: MyTabs, navigationOptions:(props) => ({
headerRight:
<TouchableOpacity onPress={() => {props.screenProps.myDrawerNavigation.navigate('DrawerOpen')}}>
<Text>Open Drawer</Text>
</TouchableOpacity>
})}
}
, {navigationOptions:commonNavigationOptions})
const MyDrawer = DrawerNavigator({
stack1: {
screen: ({navigation}) => <MyStack screenProps={{myDrawerNavigation:navigation}} />,
},
stack2: {
//more screen
}
})

React-native: How to get navigationOptions with Custom TabBarComponent

I'm new to react native and i'm trying to build a custom tab bar but i'm facing a problem when trying to display icons tab bar.
Here what i achieve so far.
Here my Custom TabBar component:
class TabBar extends Component {
renderItem = (route, index) => {
const {
navigation,
jumpToIndex,
} = this.props;
const isCapture = route.routeName === 'AddExpenses';
const focused = index === navigation.state.index;
const color = focused ? activeTintColor : inactiveTintColor;
if (isCapture === true) {
return (
<TouchableOpacity
key={route.key}
style={Styles.tab}
onPress={() => (navigation.navigate('AddExpensesModal'))}
>
<Ionicons
name={ioniconsByPlatform('add-circle')}
style={Styles.icon}
size={26}
/>
</TouchableOpacity>
);
}
return (
<TouchableWithoutFeedback
key={route.key}
style={Styles.tab}
onPress={() => (isCapture ? navigation.navigate('CaptureModal') : jumpToIndex(index))}
>
<View style={Styles.tab}>
<Text style={{ color }}>{route.routeName}</Text>
</View>
</TouchableWithoutFeedback>
);
}
render() {
const {
navigation,
} = this.props;
const {
routes,
} = navigation.state;
return (
<View style={Styles.tabBar}>
{routes && routes.map(this.renderItem)}
</View>
);
}
}
export default TabBar;
My Tab Navigator:
const MainTabNavigator = TabNavigator({
Summary: { screen: SummaryScreen },
AddExpenses: { screen: ExpensesScreen },
Expenses: { screen: ExpensesScreen },
}, {
tabBarComponent: TabBar,
});
export default MainTabNavigator;
And an example of a screen where i try to set my TabBarIcon:
const SummaryScreen = () => (
<View style={Styles.container}>
<Text>Summary</Text>
</View>
);
SummaryScreen.navigationOptions = {
title: 'Summary',
tabBarIcon: props => <TabBarIcon {...props} name="pulse" />,
};
export default SummaryScreen;
I want to be able to display my tab bar icons thanks to the navigationOptions property.
Do you have any idea how i can do this ?
If you feel TabNavigator is not powerful enough(which I think it's far from powerful), you could always customize a navigator view.
Here is my notes for customize a navigator view to replace TabNavigator:
export default class SectionTabView extends React.Component {
static propTypes = {
navigation: PropTypes.object
};
constructor(props) {
super(props);
}
render() {
const {router, navigation} = this.props;
const {routes, index} = navigation.state;
/**
* ActiveScreen is the current screen you see when you change you navigation state in tab bar
*/
const ActiveScreen = router.getComponentForState(navigation.state);
return (
<View style={Styles.section_container}>
<ActiveScreen
navigation={addNavigationHelpers({
...navigation,
state: routes[index],
})}
/>
<SectionTabBar navigation={navigation}/>
</View>
);
}
}
export default class SectionTabBar extends React.Component {
static propTypes = {
navigation: PropTypes.object
};
constructor(props) {
super(props);
}
getTabButtomGroupView() {
const {navigation} = this.props;
const {routes, index} = navigation.state;
let tabButtomGroupView = [];
routes.map((route) => {
let styles = [Styles.eventSection_tab];
const isClicked = routes[index].routeName === route.routeName;
if(isClicked){
styles.push(Styles.eventSection_tabClicked);
}
tabButtomGroupView.push(
<TouchableOpacity
onPress={() => {
/**
* when the routeName is equal to current routeName, we should stop navigate action
*/
if (routes[index].routeName === route.routeName) {
return;
}
navigation.navigate(route.routeName);
}}
style={styles}
key={route.routeName}>
<Text style={{color:'white'}}>{SectionRouteConfig[route.routeName].navigationOptions.title}</Text>
</TouchableOpacity>
)
});
return tabButtomGroupView;
}
render() {
return (
<View style={Styles.section_tabContainer}>
{this.getTabButtomGroupView()}
</View>
);
};
}
//SectionRouteConfig.js
export const sectionRouteConfig = {
XXX: {
screen: XXX, navigationOptions: {
title: XXX
}
},
XXX: {
screen: XXX, navigationOptions: {
title: XXX
}
}
};
export const SectionNavigator = createNavigator(TabRouter(sectionRouteConfig))(SectionTabView);
//Usage
render() {
const {dispatch, navigationState} = this.props;
return (
<SectionNavigator
navigation={
addNavigationHelpers({
dispatch: dispatch,
state: navigationState
})
}
/>
)
}
by the way I also use redux.
If those codes are too much for you , you can check the official example here:https://github.com/react-community/react-navigation/blob/master/examples/NavigationPlayground/js/CustomTabs.js

Change screen FlatList onPress

I have two screen.
First screen is HomeScreen, second screen is ProfileScreen.
I used FlatList on HomeScreen and i wanna push to navigation to another screen. But when i used that codes, i saw that error message: "Can not read property 'navigate' of undefined"
Code like that
class ProfileScreen extends Component {
static navigationOptions = {
title: 'Profile',
};
render() {
const { navigate } = props.navigation;
return <Text>Hello, I am profile!</Text>;
}
}
class HomeScreen extends Component {
static navigationOptions = {
title: 'Home',
};
constructor(props) {
super(props);
this.state = {
data: [],
};
}
getScreen() {
this.props.navigation.navigate('Profile')
}
render() {
return (
<View>
<FlatList
data={this.state.data}
renderItem={({ item }) => (
<TouchableHighlight underlayColor= 'transparent' onPress= {this.getScreen}>
<View style= {{width: 300, height: 'auto'}} >
<Text> {item.title} </Text>
<View style= {{width: 300, height: 1, backgroundColor: 'red', marginBottom: 30, marginTop: 15}} />
</View>
</TouchableHighlight>
)}
/>
</View>
);
}
}
const AppNavigator = StackNavigator({
Home: { screen: HomeScreen },
Profile: { screen: ProfileScreen }
});
You're losing the context of this in your implementation. Fix it with function call:
renderItem={({ item }) => (
<TouchableHighlight underlayColor='transparent' onPress={() => this.getScreen()}>
...
</TouchableHighlight>
)}
In addition, you can use pattern:
const { navigate } = this.props.navigation;
navigate('Profile');
Inside the constructor bind this to your getScreen method.
Simply add following line inside constructor.
this.getScreen = this.getScreen.bind(this);
