react-native-picker-select

A Picker component for React Native which emulates the native <select> interfaces for iOS and Android

For iOS, we are wrapping a TextInput component. You can pass down your custom styling to match your other inputs.

For Android, we are using the native Picker component, but adding a pseudo-underline to emulate a typical TextInput. Additional styling can be passed down also to further customize the appearance.

For either platform, you can alternatively pass down a child element that will be wrapped in a touchable area, triggering the picker.

Styling

• iOS
  • The component wraps a TextInput without styling. In the style prop, pass a style object named inputIOS to style the input
  • Alternatively, you can pass children (such as a custom button or input) for the component to wrap
  • Other styles that can be modified for iOS are named viewContainer, icon, done, modalViewTop, modalViewMiddle, modalViewBottom, and placeholderColor
• Android
  • The default Picker component acts similiarly to a TextInput until it is tapped, although it does not include an underline
  • We emulate a typical underline, which can be modified with a style object named underline
  • The main input can be modified with the style object named inputAndroid
  • Alternatively, you can pass children (such as a custom button or input) for the component to wrap
  • Other styles that can be modified for Android are named viewContainer and placeholderColor
