replace UTF8 characters in String

Question

I have a simple string with Chinese characters in my Android application and want to replace one character with another...

As a sample, I have this code:

String old_string = "啤酒";
String new_string = old_string.replaceAll("一", "啤");
Log.d(TAG, "transformed "+old_string+" into "+new_string);

This will not do anything:

transformed 啤酒 into 啤酒

Also tried with replace instead of replaceAll without any luck.

Answer 1

您需要在replaceAll调用中切换参数的顺序：

replaceAll("啤", "--") 

Answer 2

尝试交换周围的值：

String new_string = old_string.replaceAll("啤", "一");
