无法打开文件，我链接错误吗?还是Android Studio由于某种原因没有看到它? [英] Failing to open file, am I linking it wrong? Or is Android Studio not seeing it for some reason?

问题描述

我有一个简单的.txt文件，现在只有几行，每行包含一个单词，然后是一个逗号，然后是另一个单词，代表一个非常简单的用户名，密码库.由于某种原因，尽管我无法打开该文件以从中读取文件.

I have a simple .txt file with just a couple lines in right now, each line has a word then a comma then another word, representing a very simplistic username , password bank. For some reason though I cant get the File to open to read from it.

这是我正在使用的代码....

Here is my code that I'm using....

try {
    final String PATH = "src\\main\\assets\\passwords.txt";
    Log.w("myApp", "passed");
    List<String> user_password = FileUtils.readLines(new File(PATH));
    Log.w("myApp", "passed2");

    @SuppressWarnings("unchecked") List<Credentials> credentials = (List<Credentials>) CollectionUtils.collect(user_password, new Transformer() {
        @Override
        public Object transform(Object input) {
            String cred = (String) input;
            String parsed[] = cred.split(",");
            Log.w("myApp", parsed[0]);
            return new Credentials(parsed[0], parsed[1]);
            //return credential;
        }
    });
    user = (Credentials) CollectionUtils.find(credentials, new Predicate() {
        @Override
        public boolean evaluate(Object object) {
            Credentials c = (Credentials) object;
            return c.getUserName().equals(userName);
        }
    });
} catch (IOException e) {
    System.out.print(e);
    Log.w("MyApp", "failed");
}

我尝试将 passwords.txt 文件放在不同的位置，但这似乎也不起作用.

I've tried putting the passwords.txt file in different places but that doesn't seem to work either.

推荐答案

感谢@CommonsWare，我能够通过使用InputStream和IOUtils将所有内容读取到列表中来实现我想做的事情.

Thanks to @CommonsWare I was able to achieve what I was trying to do by using InputStream and then also IOUtils to read everything into the List.

try {
        InputStream iS = this.getAssets().open("passwords.txt");
        List<String> user_password = IOUtils.readLines(iS);

        @SuppressWarnings("unchecked") List<Credentials> credentials = (List<Credentials>) CollectionUtils.collect(user_password, new Transformer() {
            @Override
            public Object transform(Object input) {
                String cred = (String) input;
                String parsed[] = cred.split(",");
                return new Credentials(parsed[0], parsed[1]);
            }
        });
        user = (Credentials) CollectionUtils.find(credentials, new Predicate() {
            @Override
            public boolean evaluate(Object object) {
                Credentials c = (Credentials) object;
                return c.getUserName().equals(userName);
            }
        });
    }catch (IOException e){
        System.out.print(e);
    }
