For React Native v0.60 and above (Autolinking)

As react-native@0.60 and above supports autolinking there is no need to run the linking process. Read more about autolinking here. This is supported by react-native-windows@0.64 and above.

iOS

CocoaPods on iOS needs this extra step:

npx pod-install

Android

No additional step is required.

Windows (expand for details)

Windows

Usage in Windows without autolinking requires the following extra steps:

Add the ReactNativePicker project to your solution.
  1. Open the solution in Visual Studio 2019
  2. Right-click Solution icon in Solution Explorer > Add > Existing Project Select D:\dev\RNTest\node_modules\@react-native-picker\picker\windows\ReactNativePicker\ReactNativePicker.vcxproj
windows/myapp.sln

Add a reference to ReactNativePicker to your main application project. From Visual Studio 2019:

Right-click main application project > Add > Reference... Check ReactNativePicker from Solution Projects.

app.cpp

Add #include "winrt/ReactNativePicker.h" to the headers included at the top of the file.

Add PackageProviders().Append(winrt::ReactNativePicker::ReactPackageProvider()); before InitializeComponent();.

MacOS

CocoaPods on MacOS needs this extra step (called from the MacOS directory)

The following steps are only necessary if you are working with a version of React Native lower than 0.60

Mostly automatic installation

  • Add import com.reactnativecommunity.picker.RNCPickerPackage; to the imports at the top of the file
  • Add new RNCPickerPackage() to the list returned by the getPackages() method
  1. Append the following lines to android/settings.gradle:
    include ':@react-native-picker_picker'
    project(':@react-native-picker_picker').projectDir = new File(rootProject.projectDir, 	'../node_modules/@react-native-picker/picker/android')
    
  2. Insert the following lines inside the dependencies block in android/app/build.gradle:
      implementation project(path: ':@react-native-picker_picker')
    

MacOS

  1. In XCode, in the project navigator, right click LibrariesAdd Files to [your project's name]
  2. Go to node_modules @react-native-picker/picker and add RNCPicker.xcodeproj
  3. In XCode, in the project navigator, select your project. Add libRNCPicker.a to your project's Build PhasesLink Binary With Libraries
  4. Run your project (Cmd+R)<

RTL Support

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

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

Usage

Import Picker from @react-native-picker/picker:

import {Picker} from '@react-native-picker/picker';

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>
