There are listeners for keyboard show and hide.

You can use these functions keyboardDidshow and keyboardDidHide for enable and disable scrollView.

import React, { Component } from 'react';
import { Keyboard, TextInput } from 'react-native';

class Example extends Component {
  componentWillMount () {
    this.keyboardDidShowListener = Keyboard.addListener('keyboardDidShow', this._keyboardDidShow);
    this.keyboardDidHideListener = Keyboard.addListener('keyboardDidHide', this._keyboardDidHide);
  }

  state {
    toScroll: false
  }

  componentWillUnmount () {
    this.keyboardDidShowListener.remove();
    this.keyboardDidHideListener.remove();
  }

  _keyboardDidShow () {
    this.setState({ toScroll: true });
  }

  _keyboardDidHide () {
    this.setState({ toScroll: false });
  }

  render() {
    const { toScroll } = this.state;
    return (
      <ScrollView scrollEnabled={toScroll}>
        <View />
      </ScrollView>
    );
  }
}
