React Native buttons are displaying at a fixed width and not adjusting as expected

Within a row, I have two buttons with a padding of 20 between them, and they are only taking up the necessary width for the button text. The width remains constant!

Here is the code for the buttons:

<View style={styles.buttonContainer}>
    
    <View style={{ paddingLeft: 20 }}>
        <Button title={tick} style={styles.button} onPress color="tomato" />
    </View>

    <View style={{ paddingLeft: 20 }}>
        <Button title="X" style={styles.button} onPress color="tomato" />
    </View>

</View>

Below is the CSS for the buttons:

.buttonContainer {
    flex: 1;
    display: flex;
    justify-content: flex-end;
}

.button {
    width: 50px; // Their width doesn't change regardless of the value set here
    height: 20px;
}

Answer №1

When working in React Native, it is important to remember that you must enclose your elements within a View and specify the width of the parent element.

For instance, in the scenario you provided, the code would look something like this:

<View style={{ paddingLeft: 30, width: 80, height: 40 }}>
    <Button title="Y" style={styles.button} color="skyblue" />
</View>

Answer №2

Ensure you enclose the button within an additional View element. The Button component will only occupy the width of its title, regardless of any styles applied.

Remember to include the onPress function; using boolean (true) as a prop is not valid.

export default function App() {
    const tick = 'tick';
    return (
        <View style={styles.buttonContainer}>
            <View style={{ paddingLeft: 20 }}>
                <Button title={tick} style={styles.button} onPress color="tomato" />
            </View>

            <View style={styles.buttonStyle}>
                <Button title="X" style={styles.button} onPress color="tomato" />
            </View>
        </View>
    );
}

const styles = StyleSheet.create({
    buttonContainer: {
        flex: 1,
        flexDirection: 'row',
        justifyContent: 'flex-end',
    },
    buttonStyle: {
        paddingLeft: 20,
        width: 200, // this approach ensures it functions correctly
    },
    button: {
        height: 20,
    },
});
