VisualizaçõesHow to set the height of button in React Native Android
I am learning React Native programming for Android mobile apps. I am making a screen where I need to set height of button. I have added button in view and set the height of using style however there is no change on button height.
/**
* LoginComponent of Myntra
* https://github.com/facebook/react-native
* @flow
*/
import React, { Component } from "react";
import { AppRegistry, Text, View, Button, TextInput } from "react-native";
class LoginComponent extends Component {
render() {
return (
<View style={{ flex: 1, flexDirection: "column", margin: 10 }}>
<TextInput
style={{
height: 40,
borderColor: "gray",
borderWidth: 0.5
}}
placeholder="Email address"
underlineColorAndroid="transparent"
/>
<TextInput
style={{
height: 40,
borderColor: "gray",
borderWidth: 0.5
}}
placeholder="Password"
secureTextEntry={true}
underlineColorAndroid="transparent"
/>
<View style={{ height: 100, marginTop: 10 }}>
<Button title="LOG IN" color="#2E8B57" />
</View>
</View>
);
}
}
AppRegistry.registerComponent("Myntra", () => LoginComponent);
Can anyone help me to set the height of button according to my requirement?

This component has limited options, so you can't resize it to a fixed height.
I recommend you to use the TouchableOpacity component to build your own button, with own properties and styles.
You can easily style it like this:
<TouchableOpacity style={{ height: 100, marginTop: 10 }}>
<Text>My button</Text>
</TouchableOpacity>

You can set the button width as per the mentioned width easily by using following method :
<View style={[{ width: "90%", margin: 10, backgroundColor: "red" }]}>
<Button
onPress={this.buttonClickListener}
title="Button Three"
color="#FF3D00"
/>
</View>

It often happens that we want to change the dimensions of the button, which by default is extended to the entire width of the parent element. While reducing its width is not a problem – it is enough to reduce the width of the parent, but changing the height is already problematic. The Button element has no style property, so apart from changing the text color on iOS and the background color on Android, we can not set much in it.
To have more control over the button, it is better to use TouchableOpacity or TouchableNativeFeedback instead.
TouchableOpacity Function Component Example -
import React, { useState } from "react";
import { StyleSheet, Text, TouchableOpacity, View } from "react-native";
const App = () => {
const [count, setCount] = useState(0);
const onPress = () => setCount(prevCount => prevCount + 1);
return (
<View style={styles.container}>
<View style={styles.countContainer}>
<Text>Count: {count}</Text>
</View>
<TouchableOpacity
style={styles.button}
onPress={onPress}
>
<Text>Press Here</Text>
</TouchableOpacity>
</View>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: "center",
paddingHorizontal: 10
},
button: {
alignItems: "center",
backgroundColor: "#DDDDDD",
padding: 10
},
countContainer: {
alignItems: "center",
padding: 10
}
});
export default App;
