react-native-screen-keyboard

Install

To get started install via npm:

 npm install react-native-screen-keyboard

Usage

Import:

 import { VirtualKeyboard } from 'react-native-screen-keyboard';

Then add it to your code:

<VirtualKeyboard
    onRef={ref => (this.keyboard = ref)}
    keyDown={this.keyDown.bind(this)}
/>

// Callback function which receives the key pressed
keyDown(key){
   // Key pressed
}

The back and custom key will pass a sting, either "back" or "custom" to the keyDown callback.

The <VirtualKeyboard /> also has a number of functions which can be triggered through refs.

back() this will execute the back action to delete one character.
setText(text) this will set the keyboard text to the given value.
displayMessage(message) this will create a popup above the keyboard displaying the given a message. The style of the popup can be customized through props.
clearMessage() this will clear the keyboard message dialog.
enable() this will enable the keyboard for input.
disable() this will disable the keyboard.
