android - 如何将 Android 二进制字典解码为人类可读的格式，如 .xml

Question

我有一个 .dict 目录，其中包含用于我的个性化键盘建议的双字母组文件。从环顾四周 Android source我收集到文件以二进制字典格式编码，描述为 here .该 wiki 页面描述了如何将 .xml 文件转换为 .dict 二进制字典，但没有描述如何将二进制字典转换为人类可读格式。从这些文件中提取人类可读数据以使用 Android 源代码中的功能的唯一方法是什么？

这里是有问题的文件:

谢谢

我不知道这是否有帮助，但引用您的陈述“如果有一些 Java 代码显示如何从二进制字典中读取单词会很棒”，也许 this将是一个好的开始。 This is the GIT

它说它返回一个单词列表，但我不确定它返回的格式是什么，也不知道它的外观。此代码 fragment 来自此页面的第 240 行。

至于如何将 .dict 二进制文件转换为人类可读的形式，我知道这不是您要专门寻找的内容，但也许它会给您一个良好的开端。看起来您可能必须像他们那样自己写一些东西来进行转换 Here .他们写了这个脚本来处理这个过程。

"Lingoes Converter is a script written in PHP that can convert .LD2/.LDX dictionaries of Lingoes into human-readable text files. The script is based on Xiaoyun Zhu analysis (lingoes-extractor) on the LD2/LDX dictionary format ."

我希望其中的一些内容至少可以给您一个开始。这是一个利基需求，绝对需要提供一个好的解决方案。我希望你能弄明白!
