推荐答案

看起来你已经完成了找到所选区域的困难部分.现在你只需要从全文中提取那个子字符串.

Seems like you've already done the hard part by finding what the selected area is. Now you just need to pull that substring out of the full text.

试试这个:

String selectedText = et.getText().substring(startSelection, endSelection);

这只是一个基本的 Java 字符串 操作.

It's just a basic Java String operation.
