我有一个recyclerview。 onClick的一项recyclerview我正在创建一个dialog。Dialog没有被解雇
Dialog获得创建的每个项目，但问题是，当我点击dialog剂量之外的剂量不会被解雇。它再次显示我点击的物品数量并创建了一个dialog。
假设我现在单击一个项目dialog变得开放，如果我在外面点击它会被关闭。现在，如果我点击另一项并在外面点击，现在又第二次显示dialog一次，下一次点击它会被解雇。

什么错吗？
请提供完整的适配器代码我知道问题 –
@Sid检查我的答案 –
你不能直接添加onTouchListener（）和onItemClickListener（）以查看回收器视图...你应该点击recylerviewRow.setOnClickListener（）以获得相同的 –
