i am very thankful for your help. I dont know the issue.......................................................................................................................................

You can change the TouchableWithoutFeedback import from react-native-gesture-handler to react-native.
import {StyleSheet, Text, View, ImageBackground, TextInput, Dimensions, KeyboardAvoidingView, TouchableOpacity, ScrollView, TouchableWithoutFeedback} from 'react-native';
Or you can go for a new component Pressable

react native keyboard does not dismiss why?

I have a keyboardavoidingview with flex 1 with an onPress function that should dismiss the keyboard but nothing happens.
import { StatusBar } from 'expo-status-bar';
import React from 'react';
import { StyleSheet, Text, View, useWindowDimensions, KeyboardAvoidingView, Keyboard } from 'react-native';
import { TouchableOpacity, ScrollView, TextInput } from 'react-native-gesture-handler';
import { AntDesign } from '#expo/vector-icons';
const Home = ({ navigation }) => {
const width = useWindowDimensions().width;
const height = useWindowDimensions().height;
return (
<KeyboardAvoidingView onPress={Keyboard.dismiss} style={styles.container}>
<View style={styles.header}>
<View style={styles.headerTop}>
<TouchableOpacity>
<AntDesign name="pluscircleo" size={42} color="#fff" />
</TouchableOpacity>
</View>
<View style={{justifyContent: 'center', alignItems: 'center'}}>
<Text style={styles.title}>Restaurant</Text>
</View>
<View style={styles.inputContainer}>
<TextInput style={styles.input} placeholder="Find Restuarants" />
</View>
</View>

margin: 10
},
input: {
color: '#333',
borderColor: '#fff',
borderRadius: 5,
padding: 6,
backgroundColor: '#fff',
width: 290
}
});
export default Home;
if I delete keyboard.dismiss and add console.log('test') then again nothing happens.
Where is my issue?
thanks for your help!
You should wrap the KeyboardAvoidingView with TouchableWithoutFeedback and remove onPress from the KeyboardAvoidingView and put it in the TouchableWithoutFeedback
import { StyleSheet, Text, View, useWindowDimensions, KeyboardAvoidingView, Keyboard, Platform, Alert, TouchableWithoutFeedback } from 'react-native';
<TouchableWithoutFeedback onPress={Keyboard.dismiss}>
<KeyboardAvoidingView style={styles.container}>
</KeybaordAvoidingView />
</TouchableWithoutFeedback>

How to design React-Native Button

I am new to react-native and I want to design such a button, I tried and searched but could not find an answer
any help would be appreciated
Look at this aproach, with radiusBorder you can achieve something close to you're looking for:
import React from 'react';
import { View, StyleSheet, TouchableOpacity, Text } from 'react-native';
export default function NAME() {
return (
<TouchableOpacity>
<View style={styles.wrapperContainer}>
<View style={styles.Container}>
<Text>Foo</Text>
</View>
</View>
</TouchableOpacity>
);
}
const styles = StyleSheet.create({
Container: {
height: 50,
width: 100,
alignItems: 'center',
background: '#1f90f0',
borderRadius: 5,
justifyContent: 'center',
borderTopLeftRadius: 50,
borderLeftWidth: 2,
borderLeftColor: 'lightgray'
},
wrapperContainer: {
background: 'lightgray',
width: 100,
}
});
You can create a custom button in react-native by using TouchableOpacity and if you want to perform any function when the user press that button you can use onPress prop.
import React from 'react';
import {TouchableOpacity, View, Text} from 'react-native';
const FunctionName = () => {
return(
<View>
<TouchableOpacity style={styles.buttonStyling}>
<Text>Button Name</Text>
</TouchableOpacity>
</View>
);
}
export defaultFunctionName;
Use TouchableOpacity instead. That way you can customize the button however you want it to be.
https://reactnative.dev/docs/touchableopacity
import React from 'react';
import {TouchableOpacity, View, Text} from 'react-native';
export default function NAME() {
return(
<View>
<TouchableOpacity style={{padding: 10, borderWidth: 1, borderColor: '#000'}}>
<Text>Text goes here</Text>
</TouchableOpacity>
</View>
);
}
Edit: This is the closest I got for what you are looking for.
import React from 'react';
import { View, StyleSheet, TouchableOpacity } from 'react-native';
export default function NAME() {
return (
<TouchableOpacity>
<View style={styles.Container}>
<View style={styles.ButtonShape} />
</View>
</TouchableOpacity>
);
}
const styles = StyleSheet.create({
Container: {
backgroundColor: 'transparent',
},
ButtonShape: {
borderLeftWidth: 20,
width: 120,
borderLeftColor: 'transparent',
borderRightColor: 'transparent',
borderTopColor: 'blue',
borderTopWidth: 50,
},
});

Button Styles not working in react native

I want to change button borderRadius,color, and padding but it doesn't work
this is my view
import * as React from 'react';
import { StatusBar } from 'expo-status-bar';
import { Button, StyleSheet, Text, View, Image} from 'react-native';
import {NavigationContainer} from '#react-navigation/native';
import {createStackNavigator} from '#react-navigation/stack';
function HomeScreen({navigation}) {
return(
<View
style={styles.container}>
<Text>Home Screen</Text>
<Button
style={styles.button}
title= "Go To Details"
onPress={()=> navigation.navigate('Details')}
/>
</View>
)
}
and this is my styles
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
button: {
width: 200,
marginTop: 20,
backgroundColor: "green",
padding: 15,
borderRadius: 50,
},
});
this is my screen
are there something that i miss?
I don't think so you can customize like your own with react native Button. But you can change something like title, color, etc. Check their doc https://reactnative.dev/docs/button
A better way is to make your own Button with your custom Style like this :
<TouchableOpacity onPress={()=> navigation.navigate('Details')}>
<View style={styles.button}>
<Text>Go To Details</Text>
</View>
</TouchableOpacity>
I'll suggest you to use View, because button from 'react-native' have some default styling and there can be some difficulty to override them, you can customise View like anything you want. just have a View and give them desired styles.
function HomeScreen({navigation}) {
return(
<View
style={styles.container}>
<Text>Home Screen</Text>
<View
style={styles.button}
title= "Go To Details"
onPress={()=> navigation.navigate('Details')}
/>
</View>
)
}
just give styles you want
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
button: {
width: 200,
marginTop: 20,
backgroundColor: "green",
padding: 15,
borderRadius: 50,
},
});

ScrollView removing TextInput keyboard in React Native

I am using TextInput with custom clear icon to clear text. As I need to keep multiple TextInputs in screen, I used a ScrollView:
import React, {Component} from 'react';
import {
View,
Text,
ScrollView,
StyleSheet,
Image,
TouchableOpacity,
TextInput,
} from 'react-native';
export default class SuccessScreen extends Component {
constructor(props) {
super(props);
this.state = {};
}
handleRightClick() {
console.log('handleRightClick');
}
render() {
return (
<ScrollView>
<View style={styles.SectionStyle}>
<TextInput style={styles.input} />
<TouchableOpacity
style={styles.ImageStyle}
onPress={this.handleRightClick}>
<Image source={require('../../images/cross_icon.png')} />
</TouchableOpacity>
</View>
</ScrollView>
);
}
}
const styles = StyleSheet.create({
input: {
flex: 1,
borderColor: '#000000',
borderBottomWidth: 1,
height: 40,
fontSize: 15,
color: '#000000',
},
SectionStyle: {
flexDirection: 'row',
minWidth: '100%',
height: 40,
},
ImageStyle: {
height: 25,
width: 25,
marginLeft: -25,
alignContent: 'center',
resizeMode: 'stretch',
alignItems: 'center',
},
});
Without the ScrollView, handleRightClick is called, but when I use the ScrollView, it just dismiss keyboard and don't call handleRightClick.
The ScrollView has a prop keyboardShouldPersistTaps. You should set it to 'handled' so your TouchableOpacity will handle the press instead of the ScrollView.
<ScrollView keyboardShouldPersistTaps='handled'>
// ...
</ScrollView>

React Native: React Navigation using reusable component

I'am new in React Native & I'am trying to create separated Button component file (reusable component), and when I press the button it will navigate to another page (react-navigation). Below is my code:
GlobalButton.js
import React from 'react'
import { StyleSheet, TouchableOpacity, Text} from 'react-native'
import { useNavigation, NavigationContainer } from '#react-navigation/native';
const GlobalButton = (props, {screenName}) => {
const navigation = useNavigation();
return
<TouchableOpacity style={[styles.btn, props.style]} onPress= {() => navigation.navigate(screenName)}>
{props.children}
</TouchableOpacity>
}
const styles = StyleSheet.create({
btn: {
alignItems: 'center',
textAlign: 'center',
borderRadius: 25,
height: 50,
}
})
export default GlobalButton;
LoginPage.js
import React from 'react'
import { StyleSheet, Text, View, Image, TextInput, Button} from 'react-native'
import ButtonLogin from '../components/GlobalButton'
// import { useNavigation, NavigationContainer } from '#react-navigation/native';
export default function LoginPage() {
return (
<View style={styles.penampung}>
<Image source= {require('../assets/beetle.png')} style={styles.gambar}/>
<TextInput style={styles.textField} placeholder='username' />
<TextInput style={styles.textField} placeholder='password' secureTextEntry={true} />
<ButtonLogin style={styles.btnStyle} screenName="MainPage"><Text style={styles.text}>LOGIN</Text></ButtonLogin>
</View>
)
}
const styles = StyleSheet.create({
penampung: {
flex: 1,
alignItems: 'center',
backgroundColor: '#00688B',
justifyContent: 'center'
},
gambar: {
height: 100,
width: 100,
},
textField: {
marginTop: 25,
backgroundColor: '#cafafe',
borderRadius: 25,
width: '80%',
height: 50,
paddingLeft: 20
},
btnStyle: {
padding: 10,
position: 'absolute',
bottom: 20,
backgroundColor: "#fc4445",
width: '80%'
},
text:{
fontSize: 20,
fontWeight: 'bold',
color: 'white'
}
})
What I'am expecting is that when I click the login button it should navigate to the MainPage.js, but instead it gives error message ->
Error: You need to specify name or key when calling navigate with an object as the argument.
Please anyone help me in this matter, Thanks...
You should do like below as screenName is part of your props,
<TouchableOpacity style={[styles.btn, props.style]} onPress= {() => navigation.navigate(props.screenName)}>
