const [selectedLanguage, setSelectedLanguage] = useState();
Add Picker like this:
<Picker
selectedValue={selectedLanguage}
onValueChange={(itemValue, itemIndex) =>
setSelectedLanguage(itemValue)
}>
<Picker.Item label="Java" value="java" />
<Picker.Item label="JavaScript" value="js" />
</Picker>
If you want to open/close picker programmatically on android (available from version 1.16.0+), pass ref to Picker:
const pickerRef = useRef();
function open() {
pickerRef.current.focus();
}
function close() {
pickerRef.current.blur();
}
return <Picker
ref={pickerRef}
selectedValue={selectedLanguage}
onValueChange={(itemValue, itemIndex) =>
setSelectedLanguage(itemValue)
}>
