Question

你好在下面的截图中显示用户的所有朋友，这些朋友是user3，user1，user11。新的是groupname现在，我的问题是它在friendsname之后显示groupname三次。但是我只想要一次性显示groupname。我想显示像这个user3，user1，user11和New我希望显示的完全像这样1。关闭此活动后，如果我打开相同的活动意味着groupname不显示它只显示朋友的名字

但我希望在关闭此活动时，Groupname应显示为常量。

这是我的代码样品scrren拍摄：

user3
New
_________
user1
New
______
user11
New
