组中m3u上的文件解析器

Question

我正在从事android studio项目。 我想解析应用程序读取的文件，并按组对数据进行排序。 数据会像这样：

TEAM -- Real Madrid -- Player -- Cristiano Ronaldo -- Position -- Front Player;
TEAM -- Real Madrid -- Player -- Casillas -- Position -- GoalKeeper;
TEAM -- BARÇA -- Player -- Messi -- Position -- Delantero;

我可以解析数据，但是我不知道如何将它们分组在皇马-巴萨，以及在这些分组中的位置，例如前锋球员，守门员，防守球员等。

我只想对团队和职位进行分组，但是我不知道是否需要在活动中添加一个按钮并创建一个新活动。 如果您需要更多信息，可以发布更多代码。
