Java Linux、OSX和Android根据区域设置排序不一致

java android bash sorting

Java Linux、OSX和Android根据区域设置排序不一致,java,android,bash,sorting,Java,Android,Bash,Sorting,我试着为Android、Linux和OSX获得相同的排序顺序。我将Linux和OSX的sort命令结果与所以android上的自定义代码可以在类似的文件集上运行在Linux/OSX上，我使用以下命令： find {folder_name} -type f | sort 在java/android中，我使用的是这个-但是排序顺序不对齐： private Enumeration<InputStream> getSortedStreams(HashMap<String,I

我试着为Android、Linux和OSX获得相同的排序顺序。我将Linux和OSX的sort命令结果与所以android上的自定义代码可以在类似的文件集上运行

在Linux/OSX上，我使用以下命令：

find {folder_name} -type f | sort

在java/android中，我使用的是这个-但是排序顺序不对齐：

 private Enumeration<InputStream> getSortedStreams(HashMap<String,InputStream> collection) {

    Vector<InputStream> fileSreams = new Vector<>();

    List<String> keys = new ArrayList(collection.keySet());

    Collator collator = Collator.getInstance(Locale.US);//<<???
    Collections.sort(keys,collator);
    for (String key: keys) {
        Log.d(TAG, "getSortedStreams: " + key);
        fileSreams.add(collection.get(key));
    }

    return fileSreams.elements();
}

OSX输出：

1000/abc-d.txt
1000/abc_d.txt

我假设差异是因为使用的地区不同对文件列表进行排序。据我所知，OSX和Linux都是 POSIX兼容，尽管Linux未经认证。Android也不兼容POSIX，但我想它在排序方面也不错

我下面有一些细节，试图解释清楚，并得到一致的结论跨平台体验

看起来我可以控制Linux和Android对齐，但是OSX忽略了我设置的环境变量

我需要特定的帮助来设置区域设置，以便获得一致的结果穿过平台

我还没有在IOS上做过测试，如果需要我可以提交

在FedoraLinux Core 17-3.9.10-100.fc17.x86_64上

区域设置-适用于en_US的区域设置为：

locale -a | grep en_US

en_US
en_US.iso88591
en_US.iso885915
en_US.utf8

使用C

find sort_test/ -type f | env -i LC_COLLATE=C sort

sort_test/abc_d.txt

  find sort_test -type f | env -i LC_COLLATE=C sort

使用en_US.utf8

find sort_test/ -type f | env -i LC_COLLATE=en_US.utf8 sort

Locale=newlocale（“en”、“US”、“POSIX”）；他们都应该按字母顺序排列。你能给出它们都产生的输出吗？另外，也许你应该在返回它之前对文件流进行排序，而不是键
。没有理由对键进行排序
，因为您只需按原始顺序从HashMap中获取值。我已使用一些输出更新了问题。看起来Android和Bash的处理方式不一样。正如我在第二条评论中所说的，我不认为你在添加到向量之前真的在排序任何东西。HashMap顺序是不能保证的，所以不管键的顺序是什么，您真正关心的是值。我按如下方式阅读代码：我传入一组字符串，即文件名和实际文件内容。然后，我根据文件名对集合进行排序，然后检索相应的文件内容，并按排序顺序添加到最初为空的fileStreams集合中。
