java-如何从文本文件中获取特定行到一行并在android中显示数组列表

我有一个文本文件,并且能够读取全部内容并将其显示在视图上.
文本文件的示例格式示例：-

## userdetail 

   [William]
   [Bits]
   6th cross road, City house.
   Rio.
   <051-22345690>|<002-22345690>

## calldetails

    income 22.
    out going 24.
    missed 21.


## Lorempsum
 Lorem Ipsum is simply dummy text of the printing and typesetting industry. 
 Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, 
 when an unknown printer took a galley of type and scrambled it to make a type specimen book 


## userot 
 It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout.                  

………..
………..
………..

但是我的要求是我需要从字段名称中获取特定数据.我可以获取所有唯一ID的“ ## userot”值.但是我需要没有哈希映射的中间数据的详细信息.
有时数据也位于下一行.我的意思是,在某些情况下,我有5行,
在另一行中有10行文字.因此,我需要“ ##”下面的所有行,直到下一个“ ##” –

朋友请给我解决办法吗？

解决方法:

下面的解决方案是找到’## userot’之后的所有行,直到下一个##

FileInputStream fileIn = openFileInput("mytextfile.txt");
InputStreamReader inputRead = new InputStreamReader(fileIn);
BufferedReader reader = new BufferedReader(inputRead);

while ((str = reader.readLine()) != null){
    if(str.contains("##") && str.contains("userot"){
        while ((str = reader.readLine()) != null){
            if(str.contains("##"))
              break;
            else
              Log.d("TAG","output: " + str);
        }
        break;
     }
}
