Matcher 跳过第一场比赛？或者我做错了什么
Matcher its skipping the first match ? Or i'm doing something wrong
我对 android 中的匹配器和模式有一些奇怪的问题。它总是跳过第一场比赛，我不知道为什么。我是正则表达式的新手，该表达式在我在网上找到但在我的测试应用程序中找不到的测试器上运行完美
我正在搜索的字符串“

}
它是我缺少的东西吗？
它跳过第一个匹配项的原因是每次调用 matcherQ.find() 都算作一个匹配项，因此下一个调用将始终查找下一个匹配项。
请注意，在第 4 行的 while 循环之前。您已经在第 3 行调用了 matcherQ.find() 来检查是否找到了匹配项。
删除以下行，因为您没有在此代码段中使用它。
boolean matchFound = matcherQ.find();

它是我缺少的东西吗？
它跳过第一个匹配项的原因是每次调用 matcherQ.find() 都算作一个匹配项，因此下一个调用将始终查找下一个匹配项。
请注意，在第 4 行的 while 循环之前。您已经在第 3 行调用了 matcherQ.find() 来检查是否找到了匹配项。
删除以下行，因为您没有在此代码段中使用它。
boolean matchFound = matcherQ.find();
