我有一个来自API响应的字符串，希望将其拆分为一个句子的末尾（使用'。'分隔符）或某个长度，以便它可以适合我的应用程序的显示。
这是我用定界符分割字符串的方式：
String[] splitDescription = displayOcrString.split("\\.");
示例输出：
singleEntry: Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua

2018-12-04 14:40:16.860 22138-23068/com.irisvision.realityviewer W/MainActivity: readLinesFromImage: length: 110
这是我尝试将定界符和固定长度（50）都合并到正则表达式中的方式：
String[] splitDescription = displayOcrString.split("(?<=\\G.{50})|\\.");
示例输出：

2018-12-04 14:42:53.619 24191-25540/com.irisvision.realityviewer W/MainActivity: readLinesFromImage: singleEntry: Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum

但是，正如您所看到的，我没有获得所需的输出。我希望每个字符串条目都可以减少一个句点或将其长度减少为50。
感谢您的帮助。
