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>

I am fairly new to Navigation in react-native but i have been able to pick up few things here now i want o add the Hamburger icon to it to do a Proper Menu bar. Since i am fairly new to this, I need help in every way.
My code Looks something like this
import React , {Component} from 'react';
import { View, Text, Image , StyleSheet } from 'react-native';
import { createAppContainer } from 'react-navigation';
import { createDrawerNavigator } from 'react-navigation-drawer';
class Home extends React.Component{
static navigationOptions = {
drawerLabel: 'Home',
drawerIcon: ({ tintColor }) => (
<Image
source={{uri:'http://imageholder.freeasphost.net/home.png'}}
style={[styles.icon, { tintColor: tintColor }]}
/>
),
};
render()
{
return(
<View>
<Text> Welcome to Home screen</Text>
</View>
);
}
}
class Profile extends React.Component{
static navigationOptions = {
drawerLabel: 'Profile',
drawerIcon: ({ tintColor }) => (
<Image
source={{uri:'http://imageholder.freeasphost.net/profile.png'}}
style={[styles.icon, { tintColor: tintColor }]}
/>
),
};
render()
{
return(
<View>
<Text>Welcome to Profile screen</Text>
</View>
);
}
}
class Settings extends React.Component{
static navigationOptions = {
drawerLabel: 'Settings',
drawerIcon: ({ tintColor }) => (
<Image
source={{uri:'http://imageholder.freeasphost.net/settings.png'}}
style={[styles.icon, { tintColor: tintColor }]}
/>
),
};
render()
{
return(
<View>
<Text>Welcome to Settings Screen</Text>
</View>
);
}
}
const MyDrawerNavigator = createDrawerNavigator({
Home:{
screen:Home
},
Settings:{
screen:Settings
},
Profile:{
screen:Profile
},
});
const MyApp = createAppContainer(MyDrawerNavigator);
export default class App extends Component {
render() {
return (
<MyApp/>
);
}
}
const styles = StyleSheet.create({
icon: {
width: 24,
height: 24,
},
});
Like i wanted to use some drawer navigation uri to do it but how to start is the main worry, hence I wanted to know how and what i must do.
I'll always prefer making your own custom component rather than any library.
It's simple, first download icon like this or your icon and create a view box, and then on the image add touchable opacity so that when a user clicks, it will expand
will turn into this
Now steps are like that,
renderUnExpanded=()=>(
<View>
<TouchableOpacity onPress = {this.flipState} >
<Icon />
</TouchableOpacity>
<View>
)
renderExpanded = () =>(
<View>
<TouchableOpacity onPress = {this.flipState} >
<Icon />
</TouchableOpacity>
<ProfileIcon />
<SignoutIcon />
<View>
)
now flipState will be a function to toggle expanded state,
flipState =() => {
this.setState({optionVisible:!this.state.optionVisible})
}
and now in render function , show accordingly to state,
render(){
return(
{this.state.optionVisible?this.renderExpanded():this.renderUnExpanded()}
)
}
hope its clear, otherwise ask any doubts
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.
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
}
})
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);
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>
);
}

class Home2Screen extends React.Component {
