阅读资产文件作为字符串 [英] Read Assets file as string

问题描述

我想读一个资产文件作为字符串，我试着像20个答案在这里，但他们不为我工作。

I'm trying to read a assets file as string, I tried like 20 answers here but they don't work for me.

我在我的资产文件夹中的文件：data.opml，我必须把内容串。我把它像：

I have a file in my assets folder: data.opml, and I have to put the content in a string. I send it like:

 OPML.importFromFile(string, MainTabActivity.this);

和接受它喜欢的：

 importFromFile(String filename, Context context); 

东西没有工作（但它不是一个资产文件）：

Something that did work (but it's not a assets file):

 OPML.importFromFile(new StringBuilder(Environment.getExternalStorageDirectory().toString()).append(File.separator).append(fileNames[which]).toString(),MainTabActivity.this);

我已经试过：

I've tried:

 AssetFileDescriptor descriptor = getAssets().openFd("data.opml");
 FileReader reader = new FileReader(descriptor.getFileDescriptor());
 And also:
 InputStream input = getAssets().open("data.opml");
 Reader reader = new InputStreamReader(input, "UTF-8");

莫比我做得不对，但它是行不通的，因为它的项目为错误（分别为：OPML不能够对参数的FileReader和读写器），如果有人知道如何做到这一点，那将是非常AP preciated！

Maby I'm doing something wrong, but it just won't work because it the project gives errors (respectively: OPML is not capable for the arguments filereader and reader) , If somebody knows how to do this, it would be very appreciated!

推荐答案

getAssets（）。打开（）将返回的InputStream 。阅读从使用标准的Java I / O：

getAssets().open() will return an InputStream. Read from that using standard Java I/O:

    StringBuilder buf=new StringBuilder();
    InputStream json=getAssets().open("book/contents.json");
    BufferedReader in=
        new BufferedReader(new InputStreamReader(json, "UTF-8"));
    String str;

    while ((str=in.readLine()) != null) {
      buf.append(str);
    }

    in.close();

和，在未来，请解释完全和precisely 你所说的不工作，因为这解释是不是非常有帮助。意思

And, in the future, please explain completely and precisely what you mean by "don't work", as that explanation is not very helpful.
