Change the default React Native <Picker> drop-down arrow icon

Change the default React Native <Picker> drop-down arrow icon

To change the default drop-down arrow icon of the <Picker> component in React Native, you have a few options. The Picker component does not natively support changing the drop-down arrow icon directly. Instead, you can use custom styling and alternative libraries to achieve this effect. Below are the steps and options for customizing the drop-down arrow icon in a React Native <Picker>.

1. Using Custom Styling with a Wrapper Component

You can create a custom picker component using a combination of the TouchableOpacity component and the Picker component. This allows you to customize the drop-down arrow icon:

Example:

import React, { useState } from 'react'; import { View, Text, TouchableOpacity, Image, StyleSheet, Modal } from 'react-native'; import { Picker } from '@react-native-picker/picker'; // Install with npm install @react-native-picker/picker const CustomPicker = ({ options, selectedValue, onValueChange }) => { const [isVisible, setIsVisible] = useState(false); return ( <View style={styles.container}> <TouchableOpacity onPress={() => setIsVisible(true)} style={styles.pickerButton}> <Text style={styles.pickerText}> {selectedValue || 'Select an option'} </Text> <Image source={require('./path/to/custom-arrow-icon.png')} // Your custom icon style={styles.arrowIcon} /> </TouchableOpacity> <Modal transparent visible={isVisible} onRequestClose={() => setIsVisible(false)} > <View style={styles.modalContainer}> <Picker selectedValue={selectedValue} onValueChange={(itemValue) => { onValueChange(itemValue); setIsVisible(false); }} > {options.map((option) => ( <Picker.Item key={option.value} label={option.label} value={option.value} /> ))} </Picker> </View> </Modal> </View> ); }; const styles = StyleSheet.create({ container: { margin: 10, }, pickerButton: { flexDirection: 'row', alignItems: 'center', borderColor: '#ccc', borderWidth: 1, borderRadius: 4, padding: 10, }, pickerText: { flex: 1, }, arrowIcon: { width: 20, height: 20, }, modalContainer: { flex: 1, justifyContent: 'center', backgroundColor: 'rgba(0,0,0,0.5)', }, }); export default CustomPicker;

2. Using a Third-Party Library

Another option is to use a third-party library that provides a custom picker component with more flexibility, such as react-native-dropdown-picker or react-native-picker-select.

Example with react-native-dropdown-picker:

  1. Install the package:

    npm install react-native-dropdown-picker

  2. Use the custom picker component:

    import React, { useState } from 'react'; import DropDownPicker from 'react-native-dropdown-picker'; import { StyleSheet, View } from 'react-native'; const CustomDropDown = () => { const [open, setOpen] = useState(false); const [value, setValue] = useState(null); const [items, setItems] = useState([ { label: 'Option 1', value: 'option1' }, { label: 'Option 2', value: 'option2' }, { label: 'Option 3', value: 'option3' }, ]); return ( <View style={styles.container}> <DropDownPicker open={open} value={value} items={items} setOpen={setOpen} setValue={setValue} setItems={setItems} dropDownContainerStyle={styles.dropDownContainer} textStyle={styles.textStyle} arrowIconStyle={styles.arrowIconStyle} // Custom arrow icon style style={styles.pickerStyle} // Custom picker style /> </View> ); }; const styles = StyleSheet.create({ container: { margin: 10, }, dropDownContainer: { backgroundColor: '#fafafa', }, textStyle: { fontSize: 16, }, pickerStyle: { borderColor: '#ccc', borderWidth: 1, }, arrowIconStyle: { width: 20, height: 20, }, }); export default CustomDropDown;

Note: Check the documentation of the third-party library for specific customization options.

3. Customizing the Arrow Icon with Styles

If you are using a wrapper component as shown in the first example, you can directly style the arrow icon as needed:

<Image source={require('./path/to/custom-arrow-icon.png')} // Your custom icon style={styles.arrowIcon} />

Ensure that the custom icon is added to your project and its path is correctly specified.

Summary

  • Wrapper Component: Create a custom picker component using TouchableOpacity and Modal to fully control the appearance, including the drop-down arrow.
  • Third-Party Libraries: Use libraries like react-native-dropdown-picker for built-in customization options.
  • Direct Styling: For basic customization, style the components directly using React Native's styling system.

By using these methods, you can effectively change and customize the drop-down arrow icon in your React Native application.
