react-native checkbox example?
Any simple example of getting a react-native CheckBox to work/render? That is the CheckBox that now seems to be part of react-native as mentioned here: http://facebook.github.io/react-native/docs/checkbox.html
Right now CheckBox component is only supported on Android. As it is stated here, for iOS you should use Switch.
For Android, usage is pretty straight forward.
<View style={{ flexDirection: 'column'}}>
<CheckBox />
<View style={{ flexDirection: 'row' }}>
<CheckBox
value={this.state.checked}
onValueChange={() => this.setState({ checked: !this.state.checked })}
/>
<Text style={{marginTop: 5}}> this is checkbox</Text>
</View>
</View>
View and Text components are optional, just to show how CheckBox can be used along with those. Code above will produce this screen on Android device.
And this on iOS device
Using react-native-elements, the mission is easier and examples are available :
import { CheckBox } from 'react-native-elements'
<CheckBox
title='Click Here'
checked={this.state.checked}
/>
<CheckBox
center
title='Click Here'
checked={this.state.checked}
/>
<CheckBox
center
title='Click Here'
checkedIcon='dot-circle-o'
uncheckedIcon='circle-o'
checked={this.state.checked}
/>
<CheckBox
center
title='Click Here to Remove This Item'
iconRight
iconType='material'
checkedIcon='clear'
uncheckedIcon='add'
checkedColor='red'
checked={this.state.checked}
/>
For starters who's not understood the above answers
import React, { Component } from 'react';
import { Platform, View, Text, CheckBox } from 'react-native';
var tempCheckValues = [];
export default class App extends Component {
constructor(props) {
super(props);
this.state = {
checkBoxChecked: []
}
}
checkBoxChanged(id, value) {
this.setState({
checkBoxChecked: tempCheckValues
})
var tempCheckBoxChecked = this.state.checkBoxChecked;
tempCheckBoxChecked[id] = !value;
this.setState({
checkBoxChecked: tempCheckBoxChecked
})
}
render() {
const products = [{
id: 1
},
{
id: 2
},
{
id: 3
}];
return (
products.map((val) => {
{ tempCheckValues[val.id] = false }
return (
<View key={val.id} style={{ flexDirection: 'column' }}>
<CheckBox
value={this.state.checkBoxChecked[val.id]}
onValueChange={() => this.checkBoxChanged(val.id, this.state.checkBoxChecked[val.id])}
/>
</View >
)
}
)
);
}
}
