Here is my code

console.log('called');
this.props.navigation.navigate('Signup');
}
}
const Stacks = StackNavigator({
Login: {
screen: Login
},
Signup:{
screen: Signup
}
});

Answer 1

Render the StackNavigator in your index.ios.js and move the button to the Login component:
const Stacks = StackNavigator({
Login: {
screen: Login
},
Signup:{
screen: Signup
}
});
class tapak extends Component {
render() {
return (
<Stacks />
);
}
}
Login.js :
export default class Login extends Component {
constructor(props) {
super(props);
this.buttonPress = this.buttonPress.bind(this);
}
buttonPress() {
console.log('called');
this.props.navigation.navigate('Signup');
}
render() {
return (
<View style={styles.container}>
<Text style={{color: 'blue'}} onPress={this.buttonPress}>sign up</Text>
</View>
);
}
}

Write this code to index.ios.js
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
View
} from 'react-native';
import {StackNavigator} from 'react-navigation';
import Login from './src/screens/Login';
import Signup from './src/screens/Signup';
const Stacks = StackNavigator({
Login: {
screen: Login
},
Signup:{
screen: Signup
}
});
Login.js
import React ,{Component} from 'react';
import {
Text, View , Button,Image,
} from 'react-native';
export default class HomeScreen extends Component {
render() {
const { navigate } = this.props.navigation;
return (
<View>
<Text
onPress={() => navigate('Signup')}
> SignUp</Text>
</View>
);
}
}
Hope this help you.

I think you need to include navigationOptions, for example:
class MyComponent extends React.Component {
static navigationOptions = {
title: 'Great',
// other configurations
}
render() {
return (
// your view
)
}
}
Also yu need to make sure you use AppRegistry.registerComponent('glfm', () => Stacks); rather than AppRegistry.registerComponent('glfm', () => tapak);

Answer 4

The only answer to this question is to just put const { navigate } = this.props.navigation in your render() function and then you can use it in any component that you need
For Example
render() {
const { navigate } = this.props.navigation;
return (
<View>
<Text>This is the home screen of the app</Text>
<Button
onPress={() => navigate('Profile', { name: 'Brent' })}
title="Go to Brent's profile"
/>
</View>
);
}
