RTL Support

you need to add android:supportsRtl="true" to AndroidManifest.xml

   <application
      ...
      android:supportsRtl="true">

Usage

Import Picker from react-native-picker-serve:

import {Picker} from 'react-native-picker-serve';

Create state which will be used by the Picker:

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)
  }>
  <Picker.Item label="Java" value="java" />
  <Picker.Item label="JavaScript" value="js" />
</Picker>
