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.

Open the solution in Visual Studio 2019
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)

pod install

React Native below 0.60 (Link and Manual Installation)

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

Mostly automatic installation

$ react-native link @react-native-picker/picker

Manual installation

iOS

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

Android

Open application file (android/app/src/main/java/[...]/MainApplication.java)

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

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')

Insert the following lines inside the dependencies block in android/app/build.gradle:
```
  implementation project(path: ':@react-native-picker_picker')
```

MacOS

In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
Go to node_modules ➜ @react-native-picker/picker and add RNCPicker.xcodeproj
In XCode, in the project navigator, select your project. Add libRNCPicker.a to your project's Build Phases ➜ Link Binary With Libraries
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>
