我正在使用FlexboxLayout在 android 中显示芯片，但卡在 UI 我想在第二行末尾显示芯片数量的地方，如下图所示
根据上述设计，我想在第二行之前显示芯片，不适合第二行的芯片应该增加芯片末尾的芯片数
我检查的是
1- FlexboxLayout setMaxLine(2); 但在这种情况下，用户界面只有两条线绘制，第二条线是拉伸
2- FlexboxLayout getFlexLineInternel() - 这个 API 给出了错误的结果。在行中添加 1 项后行数增加，然后它给出getFlexLineInternel().size() == 2 这意味着视图已经添加到第三行但我只想限制 2 行。
3- 尝试使用 Material Chip 和 ChipGroup - 它没有给我在 chipGroup 中绘制的线数
4-尝试使用类似于ChipGroup的 Flowlayout。没有给我按布局绘制的行数，以便我可以在第二行末尾显示计数
请给我建议什么对我的情况有帮助
这是我的代码

根据上面的代码，它看起来像下图
