I'm using RNPickerSelect
in my React Native app. I want to have three options: A
B
and C
. I want A
to be selected by default (like how USA
is often selected by default in a picker list of countries). Here's what I tried:
<RNPickerSelect
value={{label: 'A', value: 'A'}}
items={[
{ label: 'A', value: 'A' },
{ label: 'B', value: 'B' },
{ label: 'C', value: 'C' },
]}
onValueChange={value => {}}
/>
This does select A
by default, but the problem is that it then doesn't allow you to select any other the others after.
How should I approach this?
First make a component state like
class DropDown extends Component {
constructor() {
this.state = {
dropdownValue: 'A'
}
}
handleDropdownChange = (name) => (value) => {
this.setState({ [name]: value })
}
render() {
const { dropdownValue } = this.state
return (
<RNPickerSelect
value={dropdownValue}
items={[
{ label: 'A', value: 'A' },
{ label: 'B', value: 'B' },
{ label: 'C', value: 'C' },
]}
onValueChange={this.handleDropdownChange('dropdownValue')}
/>
)
}
}
