替换“\\"用“/"；在 Java 中 [英] Replace "\\" with "/" in Java

问题描述

我试图在 java(Android) 中用 '/' 替换 '\\' 但这似乎不起作用！

I am trying to replace '\\'with '/' in java(Android) and this does not seem to work!

String rawPath = filePath.replace("\\\\", "/");

这有什么问题吗?我已经转义 "\" 并尝试转义 '/' 但没有用.原始字符串没有任何反应.

What is wrong with this ? I have escaped "\" and tried escaping '/' but to no use. Nothing happens to the original string.

    filePath = abc\\xyz(not after escaping two \\, the original string is with two \\)
    rawPath = abc \ xyz
    expected = abc/xyz

这样做的正确方法是什么?(另一个 Windows 文件到 Android 路径转换问题)

Whats the correct way of doing this? (Another Windows file to Android path conversion prob)

推荐答案

当使用 String.replace(String, String) 时，反斜杠不需要转义两次(即使用 replaceAll - 它处理正则表达式).所以:

When using String.replace(String, String) the backslash doesn't need to be escaped twice (thats when using replaceAll - it deals with regex). So:

String rawPath = filePath.replace("\\", "/");

或者使用char版本:

String rawPath = filePath.replace('\\', '/');
