如果您必须使用正则表达式,您可以拆分,(?![^(]*\\))
如果不是,那么对字符进行一次简单的迭代就可以解决问题
String data="300x250,468x60,300x400v(480x320,768x1024,100x100),400x300v,640x480v(200x200,728x90)";
List<String> tokens=new ArrayList<>();
StringBuilder buffer=new StringBuilder();
int parenthesesCounter=0;
for (char c : data.toCharArray()){
if (c=='(') parenthesesCounter++;
if (c==')') parenthesesCounter--;
if (c==',' && parenthesesCounter==0){
//lets add token inside buffer to our tokens
tokens.add(buffer.toString());
//now we need to clear buffer
buffer.delete(0, buffer.length());
}
else
buffer.append(c);
}
//lets not forget about part after last comma
tokens.add(buffer.toString());
String[] splitedArray=tokens.toArray(new String[tokens.size()]);
//lets test what is inside our array
for (String s : splitedArray)
System.out.println(s);
输出
300x250
468x60
300x400v(480x320,768x1024,100x100)
400x300v
640x480v(200x200,728x90)
