java - 我如何在 Android 应用程序中访问一个简单的 txt 文件？

Question

我正在创建一个应用程序，其中列出了教师以及他们在我学校所做的所有事情。我有 3 个文件，一个 Teacher 类，它是一个包含 7 个字符串变量的对象，一个 TeacherList 类，我在其中获取 .txt 文件并从中提取数据以形成教师。这是我的问题所在，我应该把文件放在哪里？这是 TeacherList 代码:

package com.mthebron.mthapp;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;

public class TeacherList {
public static Teacher[] MakeList() throws FileNotFoundException{
    Teacher[] teachers=new Teacher[71]; 
    File list=new File("C:/Users/Gareth/Desktop/TeacherInformation.txt");
    Scanner iScanner=new Scanner(list);
    StringBuilder teachersBuilder=new StringBuilder();
    while(iScanner.hasNext()) {
        teachersBuilder.append(iScanner.nextLine());
        teachersBuilder.append("\n");
    }
    String fullList=teachersBuilder.toString();
    String[] seperatedList=fullList.split("'");
    String[] blah=seperatedList[0].split("\n");
    String temp=blah[0].substring(3, 9);    
    String name=temp;
    String department=blah[1];
    String planning=blah[2];
    String club=blah[3];
    String sport=null;
    String email=blah[5];
    String website=null;
    teachers[0]=new Teacher(name, department, planning, club, sport, email, website);
    System.out.println(teachers[0].getSportsCoached());
    for (int i = 1; i < seperatedList.length; i++) {
        blah=seperatedList[i].split("\n");
        name=blah[1];
        department=blah[2];
        if (blah[3].equals("null")) {
            planning=null;
        }else planning=blah[3];
        if (blah[4].equals("null")) {
            sport=null;
        }else sport=blah[4];
        if (blah[5].equals("null")) {
            club=null;
        }else club=blah[5];
        if (blah[6].equals("null")) {
            email=null;
        }else email=blah[6];
        if (blah[7].equals("null")) {
            website=null;
        }else website=blah[7];
        teachers[i]=new Teacher(name, department, planning, sport, club, email, website);
    }
    return teachers;
}

我应该把文件放在哪里，它还能作为文件对象工作吗？

Answer 1

如果你不知道把文件放在哪里你可以简单地说

File list = new File("TeacherInformation.txt")

并且会保存到本地，你可以用同样的方式访问
