阅读文本文件作为资源 [英] Read text file as resource

问题描述

我想读从资源文件words.txt。这是我想读逐行一个非常简单的，但是大的（2 MB），文本文件。我已经把文件放到/res/raw/words.txt，并尝试用下面的code打开它：

I am trying to read a file "words.txt" from a resource. It is a very simple, but large (2 MB), text file that I want to read line by line. I have put the file into /res/raw/words.txt, and try to open it with the following code:

    try 
    {   
        BufferedReader in = 
            new BufferedReader(
            new InputStreamReader(getResources().openRawResource(R.raw.words)));
        String line=in.readLine();
        T.append(line); T.append("\n");
        in.close();
    }
    catch (Exception e) { T.append(e.toString()); }

不过，我得到一个java.io.IOException异常。这不是例外找不到资源，所以资源被正确打开，但的readLine（）产生错误。

However, I get a java.io.IOException. This is not a "resource not found" exception, so the resource is opened correctly, but the readLine() produces the error.

我尝试使用的InputStream本身，与阅读（）的结果产生-1，代表EOF，就好像文件是空的。

I tried using the InputStream itself, with the result that read() produces -1, which stands for EOF, as if the file was empty.

我任何帮助吗？

直到现在我还在分手长的文件。因此，这是最好的答案我可以给。任何一个更好的主意吗？

Till now I am still splitting up long files. So this is the best answer I can give. Anyone a better idea?

推荐答案

试试这个：

InputStream is = c.getResources().openRawResource(R.raw.csv_file);
        BufferedReader br = new BufferedReader(new InputStreamReader(is));
        String readLine = null;

        try {
            while ((readLine = br.readLine()) != null) {


            }
        } catch (IOException e) {
            e.printStackTrace();
        }
