读取纯文本文件 [英] Reading a plain text file

问题描述

我知道以前可能已经讨论过这个主题，但是我找不到我的问题的答案。

我有一个包含一些我需要阅读的单词的文件。

它可以在我的桌面版本上正常工作，但是如果我尝试在模拟器上运行，则会得到 java.io.FileNotFoundException-找不到文件。

我知道我必须以不同于桌面的方式加载文件。

I know this topic probably has been covered before but I cant find an answer to the my problem.
I have a file that contains some words I need to read.
It works normally on my desktop version, but wen I try to run on an emulator, I get java.io.FileNotFoundException - no file found.
I understand I have to load the file in a different way than the desktop.

任何帮助将不胜感激。

这是读取文件的代码。

    String line;

        try {

            BufferedReader br = new BufferedReader(new FileReader("words.txt"));
            if (!br.ready()) {
                throw new IOException();
            }
            while ((line = br.readLine()) != null) {
                words.add(line);
            }
            br.close();
        } catch (IOException e) {
            System.out.println(e);
        }

，但这在Android上不起作用！

but that doesn't work on Android!!

仍然没有解决方案！

推荐答案

您可以访问文件从Android中的上下文。

You can reach a file from context in android.

Context Context;
AssetManager mngr = context.getAssets();
String line;
        try {

            BufferedReader br = new BufferedReader(new FileReader(mngr.open("words.txt")));
            if (!br.ready()) {
                throw new IOException();
            }
            while ((line = br.readLine()) != null) {
                words.add(line);
            }
            br.close();
        } catch (IOException e) {
            System.out.println(e);
        }

或尝试以下操作：

String line;
        try {

            BufferedReader br = new BufferedReader(new FileReader(getApplicationContext().getAssets().open("words.txt")));
            if (!br.ready()) {
                throw new IOException();
            }
            while ((line = br.readLine()) != null) {
                words.add(line);
            }
            br.close();
        } catch (IOException e) {
            System.out.println(e);
        }
