问题描述

问题出在这里-

这是我的ViewHolder代码-

fun <T,VH : RecyclerView.ViewHolder> RecyclerView.setAdapterWithItemdecoration(context: Context,adapter: listadapter<T,VH>) {
    this.adapter = adapter

    this.addItemdecoration(DividerItemdecoration(context,DividerItemdecoration.VERTICAL))
}

如您所见，点击区域的底部有一些空白，我不明白为什么会这样。有时会发生，有时却不会，我无法弄清楚出了什么问题。

关于我正在使用的扩展功能-我正在整个应用程序中使用它

解决方法

在您的第一个LinearLayout中，您已经定义了android:padding="10dp"。我认为这会导致不必要的利润。
