在Android中保存文件与文件名空间 [英] Save file in Android with spaces in file name

问题描述

我需要为我的Andr​​oid应用程序到一个XML文件保存到与含有空格的文件名外部缓存。

I need for my android application to save an xml file into the external cache with a file name which contains space.

DOMSource source = new DOMSource(doc);
StreamResult result = new StreamResult(new File(activity
                    .getExternalCacheDir().getAbsolutePath()
                    + "/Local storage.xml"));

transformer.transform(source, result);

当我手动浏览到我的文件目录，我找到这个文件：本地％20storage.xml

When I browse manually into my file directory I find this file : "Local%20storage.xml".

所以，以后，当我试图用读

So after when I try to read it with

File localStorageXmlFile = new File(activity.getExternalCacheDir()
                .getAbsolutePath()
                + "/Local storage.xml");

不过我有个FileNotFoundException异常，因为文件本地storage.xml不能我的设备上找到。

But I have a FileNotFoundException because the file "Local storage.xml" can't be found on my device.

任何想法解决这个？

推荐答案

这是很难确定这个问题的来源，但它来自StreamResult它通过20％替换文件的名称空间。没有针对此问题一个bug报告这里。

It was hard to identify the source of this problem but it comes from StreamResult which replaces spaces in file name by %20. There is a bug report for this issue here.

这是解决方案：

TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(doc);

FileOutputStream fos = null;
try {
    fos = new FileOutputStream(new File(activity
                .getExternalCacheDir().getAbsolutePath()
                + "/" + "Local storage" + ".xml"));
    Result fileResult = new StreamResult(fos);
    transformer.transform(source, fileResult);
} catch (FileNotFoundException e) {
    e.printStackTrace();
} finally {
    if (fos != null) {
        fos.close();
    }
}

再次感谢你们俩为试图解决我的问题。

Thanks again to both of you for trying to solve my issue.
