Android：将XML从原始文件夹转换为字符串 [英] Android: Converting an XML from the raw folder to string
问题描述
我遇到了一个让我疯狂的问题xD ......（首先：大家好！由于某种原因，我无法在编辑开头的帖子前面加上大家好...）
I have come across an issue that is driving me nuts xD ... (Firstly: Hello everyone! For some reason I cant prepend the "Hello everyone" at the beginning of the post in edits oO...)
用例如下：我有一个xml文件存储在我项目的原始文件夹中。 xml文件如下所示：
The use-case is as follows: I have an xml file stored in my project's raw folder. The xml file look something like this:
<myxml ....>Some text<innerelement ... /></myxml>
我知道有一个名为xml的文件夹，但我需要的是一个字符串 - 而不是XmlResourceParser（你在调用context.getResources（）。getXml（id））时得到。
I know there is a folder called xml but what I need is a string - not an XmlResourceParser (which you get when calling context.getResources().getXml(id)).
现在，我要加载这个原始xml文件的是：
Now, what I do to load this raw xml file is:
context.getResources().openRawResource(R.raw.myfile)
这会返回一个InputStream，然后我尝试使用以下代码转换为String：
This returns me an InputStream, which I then try to convert to a String using the following code:
try {
byte[] buffer = new byte[stream.available()];
stream.read(buffer);
stream.close();
return new String(buffer);
} catch (IOException e) {
// Error handling
}
如果我现在将生成的字符串打印到logcat，我得到的就是一堆正方形，分布在几行上。
If I now print the resulting String to logcat, all I get is a bunch of squares, spread across a few lines.
所以我想我一定不能错过那里的东西......我尝试了几种将这个输入流转换为String的方法，所有这些方法都得到了相同的结果（见上图）......
So I guess I must be missing something there ... I tried a few ways of converting this input stream to String already and all of them ended up with the same result (see image above) ...
提前致谢&最好的问候，
Thanks in advance & best regards,

UPDATE 12.11.2011
我尝试使用扩展名.txt而不是.xml将xml文件保存在raw文件夹中。现在转换失败，出现OutOfMemory异常oO。我尝试了使用此主题 - 全部导致OutOfMemoryException：
I tried saving the xml file in the raw folder using the extension .txt instead of .xml. Now the conversion fails with an OutOfMemory exception oO. I tried different way to convert the data using suggestions from this thread - all resulting in a OutOfMemoryException:

推荐答案
我把这个放了 onCreate（...）中的代码。它可以在xml文件中显示字符串。
I put this code in onCreate(...). It can show the string in the xml file.
InputStream stream = getResources().openRawResource(R.raw.data);
try {
byte[] buffer = new byte[stream.available()];
stream.read(buffer);
stream.close();
Log.i("xml", new String(buffer));
} catch (IOException e) {
// Error handling
}
