Question

所以我是新来的响应本机的人，我刚开始构建一个学习应用，这里是代码

App.js

import React from "react";
import { StyleSheet, Text, View, Button } from "react-native";

import FetchLocation from "./components/FetchLocation";
export default class App extends React.Component {
  getUserLocationHandler = () => {

  }

  render() {
    return (
      <View style={styles.container}>
        <FetchLocation onGetLocation={this.getUserLocationHandler}/>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#fff",
    alignItems: "center",
    justifyContent: "center"
  }
});

FetchLocation.js

import React from 'react';
import {Button} from 'react-native';

const fetchlocation = props => {
    return(
        <Button title="Get Location" onPress={props.onGetLocation} />
    );
};

export default fetchLocation;

这是file structure

我不认为这是一个复杂的问题，但这确实使我感到沮丧。谢谢
