Reactjs - How to dim a background in react native modal?

To dim the background when using a React Native modal, you can achieve this effect by overlaying a semi-transparent View or Modal component on top of your main content. Here's a simple example:

import React, { useState } from 'react'; import { View, Text, Modal, TouchableOpacity, StyleSheet } from 'react-native'; const MyModal = () => { const [modalVisible, setModalVisible] = useState(false); const toggleModal = () => { setModalVisible(!modalVisible); }; return ( <View style={styles.container}> <TouchableOpacity onPress={toggleModal}> <Text>Show Modal</Text> </TouchableOpacity> <Modal transparent={true} animationType="slide" visible={modalVisible} onRequestClose={toggleModal} > <View style={styles.modalContainer}> <View style={styles.modalContent}> <Text>This is the modal content</Text> <TouchableOpacity onPress={toggleModal}> <Text>Close Modal</Text> </TouchableOpacity> </View> </View> </Modal> </View> ); }; const styles = StyleSheet.create({ container: { flex: 1, justifyContent: 'center', alignItems: 'center', }, modalContainer: { flex: 1, justifyContent: 'center', alignItems: 'center', backgroundColor: 'rgba(0, 0, 0, 0.5)', // Semi-transparent background }, modalContent: { backgroundColor: 'white', padding: 20, borderRadius: 10, }, }); export default MyModal;

In this example:

  • The modalContainer style is used to create a semi-transparent background using the rgba notation for the backgroundColor property.

  • The Modal component has the transparent prop set to true to make it transparent.

  • Adjust the backgroundColor in the modalContainer style to control the degree of dimming. The fourth parameter in rgba represents the alpha (transparency) value, where 0 is fully transparent, and 1 is fully opaque.

Examples

  1. React Native modal dim background example

    // Example code to dim the background of a React Native modal <Modal transparent={true} animationType="slide" visible={modalVisible} > <View style={{ flex: 1, backgroundColor: 'rgba(0, 0, 0, 0.5)' }}> {/* Your modal content here */} </View> </Modal>

  2. React Native modal overlay background styling

    // Styling the overlay background of a React Native modal <Modal transparent={true} animationType="slide" visible={modalVisible} > <View style={{ flex: 1, backgroundColor: 'rgba(0, 0, 0, 0.7)' }}> {/* Your modal content here */} </View> </Modal>

  3. Dim background on React Native modal open

    // Dimming the background when opening a React Native modal const openModal = () => { setModalVisible(true); // Additional logic to handle modal opening }; return ( <TouchableOpacity onPress={openModal}> {/* Your component triggering the modal */} </TouchableOpacity> );

  4. React Native modal backdrop styling

    // Styling the backdrop of a React Native modal using backdropColor <Modal transparent={true} animationType="slide" visible={modalVisible} backdropColor="rgba(0, 0, 0, 0.5)" > {/* Your modal content here */} </Modal>

  5. Dimming background with React Native modal backdropOpacity

    // Dimming the background using backdropOpacity in React Native modal <Modal transparent={true} animationType="slide" visible={modalVisible} backdropOpacity={0.5} > {/* Your modal content here */} </Modal>

  6. React Native modal background blur effect

    // Adding a blur effect to the background of a React Native modal <Modal transparent={true} animationType="slide" visible={modalVisible} > <BlurView style={{ flex: 1 }} blurType="light" blurAmount={10} > {/* Your modal content here */} </BlurView> </Modal>

  7. Customizing React Native modal overlay color

    // Customizing overlay color for a React Native modal <Modal transparent={true} animationType="slide" visible={modalVisible} > <View style={{ flex: 1, backgroundColor: 'rgba(255, 0, 0, 0.3)' }}> {/* Your modal content here */} </View> </Modal>

  8. React Native modal background opacity transition

    // Adding opacity transition to the background of a React Native modal <Modal transparent={true} animationType="fade" visible={modalVisible} > <Animated.View style={{ flex: 1, backgroundColor: 'rgba(0, 0, 0, 0.5)' }} > {/* Your modal content here */} </Animated.View> </Modal>

  9. Dimming background with React Native modal onRequestClose

    // Dimming the background using onRequestClose in React Native modal <Modal transparent={true} animationType="slide" visible={modalVisible} onRequestClose={() => setModalVisible(false)} > {/* Your modal content here */} </Modal>

  10. React Native modal background tap to close

    // Closing the modal on tapping the background in React Native <Modal transparent={true} animationType="slide" visible={modalVisible} onRequestClose={() => setModalVisible(false)} > <TouchableOpacity style={{ flex: 1, backgroundColor: 'rgba(0, 0, 0, 0.5)' }} onPress={() => setModalVisible(false)} > {/* Your modal content here */} </TouchableOpacity> </Modal>
