Show a Checkbox in React Native
Checkboxes is a common component that we often use on the UI. We do have some cool ways of showing checkboxes in reactnative.
The core react-native package does not have checkbox support and you need to install a package to work with it.
Following package has to be installed to display checkbox −
npm install --save-dev react-native-paper
The basic checkbox component is as follows −
<Checkbox status={checkboxstatus} onPress={onCheckboxCheckedfunc} />
Let us now see some important properties on checkbox −
Props | Description |
---|---|
status | The value that can be given to status are
checked, unchecked and indeterminate. |
disabled | The value is boolean.It can be used to
enable/disable the checkbox. |
onPress | The function that will be called when the checkbox is checked. |
color | The color to be given to the checkbox |
uncheckColor | The color for the checkbox in unchecked mode. |
Here is a simple checkbox display −
The useState is used to set the checked , unchecked status for the checkbox as shown below −
const [checked, setChecked] = React.useState(false);
The state is maintained inside checked variable and setChecked method is used to update it.
The checked status will be updated when user checks/unchecks the checkbox as shown below −
onPress={() => { setChecked(!checked); }}
The complete code is as follows −
Example
import * as React from 'react'; import { StyleSheet, Text, SafeAreaView } from 'react-native'; import { Checkbox } from 'react-native-paper'; const MyComponent = () => { const [checked, setChecked] = React.useState(false); return ( <SafeAreaView style={styles.container}> <Checkbox status={checked ? 'checked' : 'unchecked'} onPress={() => { setChecked(!checked); }} color={'green'} uncheckColor={'red'} /> <Text>Checkbox</Text> </SafeAreaView> ); }; const styles = StyleSheet.create({ container: { flex: 1, justifyContent: 'center', alignItems: 'center' }, }); export default MyComponent;
