android用sku算法仿淘宝选择颜色分类弹框。

当规格超出边界会自动换行，点击规格会根据算法判断关联规格，无则灰显，全部选中后则变化图片。代码是kotlin和java混合。
效果如下，当一行显示不下所有规格时，会自动换行。用的夜神模拟器，分辨率有点怪。
里面用到的图片都是百度随意找的，侵删。
前面根据各自接口获取数据添加进
testData.productStocks
testData.getAttributes()下面是主要代码//选择参数弹框fun showBottomSheetDialog(view: View) { if (mUiData.getBottomSheetDialog() == null) { mUiData.getSelectedEntities().clear() val view =
