如何用React Native制作默认键盘上方的工具栏？

import React from 'react';
import { View, TextInput, TouchableOpacity, Text } from 'react-native';
import { StyleSheet } from 'react-native';

const Toolbar = () => {
  return (
    <View style={styles.toolbar}>
      <TouchableOpacity style={styles.button}>
        <Text style={styles.buttonText}>按钮1</Text>
      </TouchableOpacity>
      <TouchableOpacity style={styles.button}>
        <Text style={styles.buttonText}>按钮2</Text>
      </TouchableOpacity>
      <TouchableOpacity style={styles.button}>
        <Text style={styles.buttonText}>按钮3</Text>
      </TouchableOpacity>
    </View>
  );
};

const App = () => {
  return (
    <View style={styles.container}>
      <TextInput style={styles.input} />
      <Toolbar />
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
  input: {
    width: '80%',
    height: 40,
    borderWidth: 1,
    borderColor: 'gray',
    marginBottom: 10,
  },
  toolbar: {
    flexDirection: 'row',
    justifyContent: 'space-between',
    paddingHorizontal: 10,
  },
  button: {
    backgroundColor: 'blue',
    padding: 10,
    borderRadius: 5,
  },
  buttonText: {
    color: 'white',
  },
});

export default App;
