Escape space with backslash in java
提问by
I want to replace spaces from path string. I tried below but doesn't seems to be working :
我想替换路径字符串中的空格。我在下面尝试过，但似乎没有用：
String path = "/Users/TD/San Diego";
path=path.replaceAll(" ","\ ");
System.out.println(path);
Goal is to convert
目标是转换
"/Users/TD/San Diego" to "/Users/TD/San\ Diego"
“/Users/TD/San Diego”到“/Users/TD/San Diego”
Any further space from string also needs to be replaced with "\ "
字符串中的任何其他空格也需要替换为“\”

You could change
你可以改变
path = path.replaceAll(" ", "\ ");
to escape the backslash
逃避反斜杠
path = path.replaceAll(" ", "\\ ");
When I do that, I get (the requested)
当我这样做时，我得到（请求的）
/Users/TD/San\ Diego
Another option would be using String.replacelike
另一种选择是使用String.replace像
path = path.replace(" ", "\ ")
which outputs the same.
输出相同。

The suggested solution did not work for me (in Android Java).
建议的解决方案对我不起作用（在 Android Java 中）。
So this is what I've came up with, after quite a few attempts:
所以这是我想出的，经过多次尝试：
path = path.replace(" ", (char) 92 + " ");
