我的交错网格布局列空间发生了变化（正如您在第二行中看到的那样，两个项目之间的差距增加了一点。
这是用于在项目之间添加空间的 EqualSpacingGridItemDecoration 类：
class EqualSpacingGridItemDecoration @JvmOverloads constructor(private val spacing: Int) :
RecyclerView.ItemDecoration() {
override fun getItemOffsets(
outRect: Rect,
view: View,
parent: RecyclerView,
state: RecyclerView.State
) {
val position = parent.getChildViewHolder(view).adapterPosition
outRect.left = if (position % 2 == 0) spacing else spacing / 2
outRect.right = if (position % 2 == 1) spacing else spacing / 2
outRect.top = if (position == 0 || position == 1) 0 else spacing
outRect.bottom = 0
}
}
这是单个项目的 XML：
