Problem with lining up contents: react native - react-native

I'm currently having a problem with the clickable size of a reusable button which includes an icon and text. When I run this code it seems like the entire row becomes clickable when I only want the icon and text to become clickable. Does anyone know how to solve this problem? Thanks
App.js
import { StyleSheet, Text, View, TouchableOpacity } from 'react-native';
import IconTextButton from './components/iconTextButton';
export default function App() {
return (
<View style={styles.container}>
<Text style={{marginTop: 100}}>My First React App! Sike </Text>
<IconTextButton iconFont="ionicons" iconName="pencil" iconSize={25} text="Add Items"/>
</View>
);
}
const styles = StyleSheet.create({
container: {
backgroundColor: 'powderblue',
},
});
iconTextButton.js
import React from 'react';
import { StyleSheet, TouchableOpacity, Text, View } from 'react-native';
import Ionicon from 'react-native-vector-icons/Ionicons';
export default function IconTextButton({ iconFont, iconName, iconSize, text, onPress }) {
const getIconFont = (iconFont) => {
switch (iconFont) {
case "ionicons":
return Ionicon;
}
};
const FontIcon = getIconFont(iconFont);
return (
<TouchableOpacity onPress={onPress} style={styles(iconSize).container>
<FontIcon name={iconName} size={iconSize} style={styles(iconSize).buttonIcon}>
<Text style={styles(iconSize).buttonText}>{text}</Text>
</FontIcon>
</TouchableOpacity>
)
}
const styles = (size) => StyleSheet.create({
container: {
backgroundColor: 'pink',
},
buttonIcon: {
backgroundColor: 'yellow',
width: size,
},
buttonText: {
backgroundColor: 'green'
},
})
Along with the code I've tried, I've also tried to keep and as seperate contents whilst adding a flexDirection: 'row' inside styles.container. This keeps the contents in the same line but it still makes the whole row clickable. I've also tried putting everything in a and moving the styles.container to the component and adding a height: size into styles.container. This makes the clickable component limited however, the component is hidden underneath due to the restricted height. I have also tried simply just using instead of making a reusable const that its an input. The same thing applies.

You can wrap your Icon and Text Component in a View component and then wrap it inside a TouchableOpacity Component
Try this or do something like this :
import React from 'react';
import { StyleSheet, TouchableOpacity, Text, View } from 'react-native';
import Ionicon from 'react-native-vector-icons/Ionicons';
export default function IconTextButton({ iconFont, iconName, iconSize, text, onPress }) {
const getIconFont = (iconFont) => {
switch (iconFont) {
case "ionicons":
return Ionicon;
}
};
const FontIcon = getIconFont(iconFont);
return (
<TouchableOpacity onPress={onPress} style={styles(iconSize).container}>
<View style={styles(iconSize).iconTextContainer}>
<FontIcon name={iconName} size={iconSize} style={styles(iconSize).buttonIcon} />
<Text style={styles(iconSize).buttonText}>{text}</Text>
</View>
</TouchableOpacity>
)
}
const styles = (size) => StyleSheet.create({
container: {
backgroundColor: 'pink',
},
iconTextContainer: {
flexDirection: 'row',
alignItems: 'center',
},
buttonIcon: {
backgroundColor: 'yellow',
width: size,
},
buttonText: {
backgroundColor: 'green'
},
})

You should use KeyboardAvoidingView in your app component so that whenever keyboard gets activated then the component of App gets pushed.

How to change the style of a View, by pressing a nested Button?

I am learning React Native expo, and am trying to change the style (like background color) of a View, by pressing a Button inside it. This is what I have so far:
import { Button, View } from 'react-native';
var styles = {
container: {
flex: 1,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: 'blue'
}
};
export default function App() {
return (
<View style={styles.container}>
<Button title='button' onPress={() => styles.A.backgroundColor = 'yellow'} />
</View>
);
}
But when I press the Button, I get the error undefined is not an object (evaluating 'styles.A.backgroundColor = 'yellow'') .
What am I missing? How do I fix this?
With help and guidance from Uger Eren's comments, I was able to figure it out.
import { useState } from 'react';
import { Button, View } from 'react-native';
var styles = {
container: {
flex: 1,
alignItems: 'center',
justifyContent: 'center',
}
};
export default function App() {
var [backgroundColor, setBackgroundColor] = useState('blue')
return (
<View style={[styles.container, {backgroundColor}]}>
<Button title='button' onPress={() => setBackgroundColor('yellow')} />
</View>
);
}
It works!

Unable to navigate using reusable card components in React Native

I have this HomeScreen file, in it I have added Card component(Dashboard & Highlights), I have Customized the Card Components with the TitleCard to reuse the styling,
In each card there is "View All" Button to navigate to its individual Screens,
When I don't use the Cards and put the entire code in home screen and Click on the View All Button on home screen then it navigates to that page, but when I use the Cards and use its props to navigate to the link provided as forwardLink props then
I get this error
"ReferenceError: Can't find variable: navigation"
Also when I add this.props.navigation.navigate('{props.forwardLink}') in TitleCard
I get this error message:
TypeError: undefined is not an object (evaluating '_this.props.navigation')
Here are the codes for each file
TitleCards
import React from 'react';
import {StyleSheet, Text, View, TouchableOpacity} from 'react-native';
const TitleCards = props => {
return (<View style={styles.textTitlesContainer}>
<Text style={styles.textTitle}>{props.leftTitle}</Text>
<TouchableOpacity
onPress={() => navigation.navigate('{props.forwardLink}')}>
<Text style={[styles.textTitle, {color: '#F483A7'}]}>
{props.rightTitle}
</Text>
</TouchableOpacity>
</View>)
};
const styles = StyleSheet.create({
textTitlesContainer: {
flex: 1,
width: '100%',
flexDirection: 'row',
justifyContent: 'space-between',
padding: 5,
},
textTitle: {
fontSize: 20,
fontWeight: '800',
color: '#fff',
},
});
export default TitleCards;
HomeScreen
import React, {Component} from 'react';
import {
SafeAreaView,
ScrollView,
StyleSheet,
} from 'react-native';
import {CustomHeader} from '../index';
import Colors from '../constants/Colors';
import DashboardCard from './DashboardCard';
import HighlightCard from './HighlightCard';
export class HomeScreen extends Component {
render() {
return (
<SafeAreaView style={{flex: 0, backgroundColor: Colors.primary}}>
<CustomHeader
title="Home"
isHome={true}
navigation={this.props.navigation}
/>
<ScrollView style={styles.container}>
<DashboardCard />
<HighlightCard />
</ScrollView>
</SafeAreaView>
);
}
}
const styles = StyleSheet.create({
container: {
height:900, backgroundColor: Colors.mainBackground,
paddingTop:6,
},
});
export default HomeScreen;
HighlightCard
import React, {Component} from 'react';
import {Text, View} from 'react-native';
import {CustomHeader} from '../../index';
const HighlightCard = (prop) => {
return (
<Card>
<TitleCards leftTitle="Highlights" rightTitle="View More" forwardLink="Highlights">
</TitleCards>
<View>
<Text>News Feed</Text>
</View>
</Card>
);
};
export default HighlightCard;
const styles = StyleSheet.create({
textTitle: {
fontSize: 20,
fontWeight: '800',
color: '#fff',
},
});
When I use the HighlightCard codes directly in HomeScreen then it navigates to that page, below is that code which works if I use it directly in Home Screen
*{/* <Text style={styles.textTitle}>Highlights</Text>
<TouchableOpacity
onPress={() => this.props.navigation.navigate('Highlights')}>
<Text style={[styles.textTitle, {color: '#F483A7'}]}>View All</Text>
</TouchableOpacity> */}*
I think there is something wrong I am doing is using the props or referencing to the navigation page
I also tried creating a const for navigation
const {navigate} = this.props.navigation
this didn't worked either

How to add style customisation in Google Ads for React Native app?

I am using below package currently. But I am failing to add style customisation in my AdMobBanner component. Please tell if any other package might be useful for Google Ads customisation or any other Platform Ads that supports customisation.
https://www.npmjs.com/package/react-native-admob
Please click on this link to see my current O/P. I want to remove border and add labels and buttons below it. Is it possible?
import React, { PureComponent } from 'react';
import { ScrollView, StyleSheet, View } from 'react-native';
import { AdMobBanner } from 'react-native-admob';
const BannerExample = ({ style, title, children, ...props }) => (
<View {...props} style={[styles.example, style]}>
<View>{children}</View>
</View>
);
const adUnitID = 'ca-app-pub-3940256099942544/2934735716';
export default class GoogleAdsCompo extends PureComponent {
render() {
return (
<ScrollView>
<BannerExample title="Smart Banner">
<AdMobBanner
adSize="mediumRectangle"
adUnitID={adUnitID}
ref={el => (this._smartBannerExample = el)}

Two of my common components that I'm importing with index.js don't fire

I'm doing this course at Udemy. Files: https://github.com/StephenGrider/ReactNativeReduxCasts/tree/master/auth
The issue I'm having is with importing common components. It's only for 2 of the common components--the rest work fine. Card, CardSection, Header, Input.
When I try to import the Button or Spinner, they won't fire. But if I use the basic functionality (putting the TouchableOpacity or ActivityIndicator in the file directly and do all the styling THERE), they work fine.
Here's the file structure:
Here's /components/common/index.js
export * from './Header';
export * from './Input';
export * from './Card';
export * from './CardSection';
export * from './Button';
export * from './Spinner';
Here's Button.js
import React from 'react';
import { Text, TouchableOpacity } from 'react-native';
const Button = ({ propOnPress, children }) => {
const { buttonStyle, textStyle } = styles;
return (
<TouchableOpacity onPress={propOnPress} style={buttonStyle}>
<Text style={textStyle}>
{children}
</Text>
</TouchableOpacity>
)
}
const styles = {
textStyle: {
alignSelf: 'center',
color: '#fff',//'#007aff',
fontSize: 16,
fontWeight: '600',
paddingTop: 10,
paddingBottom: 10
},
buttonStyle: {
flex: 1,
alignSelf: 'stretch',
backgroundColor: '#007aff', //'#fff',
borderRadius: 5,
borderWidth: 1,
borderColor: '#007aff',
marginLeft: 5,
marginRight: 5,
}
}
export { Button };
Here's Spinner.js
import React from 'react';
import { View, ActivityIndicator } from 'react-native';
const Spinner = ({ size }) => {
return (
<View style={styles.spinnerStyle}>
<ActivityIndicator size={size || 'large'} />
</View>
)
}
const styles = {
spinnerStyle: {
flex: 1,
justifyContent: 'center',
alignItems: 'center'
}
}
export { Spinner }
Here's where I import them in LoginForm.js
import { Card, CardSection, Button, Spinner, Input } from './common';
And where they're used in the code in LoginForm.js
renderButton() {
//console.log('render button');
if (this.state.loading) {
console.log('returning the spinner');
return <Spinner animating={this.state.loading} size="small" />;
}
console.log('gonna return a button');
return(
<Button onPress={this.onYouPressedIt.bind(this)}>Log in</Button>
);
}
What am I doing wrong?
Issues I see with the Button.js file
Property onPress doesn't exist. You created a property called propOnPress
So, your Button component should be used like this
<Button propOnPress={}>...</Button>
Issues I see with the Spinner.js file
Property animating doesn't exist on the component. The only properties you created is size.
Solution would be to simply add an animating property to your Spinner component.
Component would end up looking like this
const Spinner = ({ animating, size }) => {
return (
{
animating ? (
<View style={styles.spinnerStyle}>
<ActivityIndicator size={size || 'large'} />
</View>
) : null
}
)
}
I assume the animating property is a boolean which if false then you don't want to display the activity indicator which is why I added the ternary operator.
