In React-native, we can customise user defined button component and call it from anywhere. So that we can have structured approach throughout the program or application.
import React from "react";
import { StyleSheet, TouchableOpacity, Text, View } from "react-native";
const MyButton = props => {
return (
<TouchableOpacity
onPress={props.onPress}
>
<View style={{...styles.buttonStyle, ...props.style,
backgroundColor:props.buttonColor,
borderColor:props.buttonColor}}>
<Text style={{...styles.TextStyle, ...props.style,
color:props.fontColor}}>
{props.children}
</Text>
</View>
</TouchableOpacity>
);
};
const styles = StyleSheet.create({
buttonStyle: {
paddingVertical: 10,
paddingHorizontal: 10,
borderRadius: 10,
borderWidth: 2,
},
TextStyle: {
textAlign: "center",
},
});
export default MyButton;
In style ... spread operator is used to integrate all the styles from same components and incoming styles from parent component through props.
props.children is used here to pass button title, so that title text is displayed on the button.
When button is pressed then instead of handling this press event inside of the button but inside of the component where we use this button. So we pass a fitting function reference on the button.
This MyButton button component can be called anywhere inside the program like:
<MyButton onPress={() => onPressFunction()}
buttonColor="red" fontColor="white">Button Title</MyButton>
<Button title="ENABLE NOTIFICATION" color="#FE434C" onPress={null} style={{ borderRadius: 40 }} />but it not making buttons roundedborderRadiusattribute facebook.github.io/react-native/docs/button.html
