在StaggeredGridLayoutManager中设置单行的跨度大小 [英] Setting span size of single row in StaggeredGridLayoutManager

问题描述

我有一个交错的网格，其中有2列.这正在工作.我想要的是在位置0处跨2列的行.我之前很容易使用GridLayoutManger做到了这一点:

I have a staggered grid that has 2 columns. This is working. What I want is at position 0 for the row to span across the 2 columns. I have done this before quite easily using GridLayoutManger as so:

                mGridLayoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
                    @Override
                    public int getSpanSize(int position) {
                        return position == 0 ? 2 : 1;
                    }
                });

StaggeredGridLayoutManager不像GridLayoutManager那样为我提供此功能.

StaggeredGridLayoutManager doesn't provide me with this functionality like GridLayoutManager does.

是否有其他方法可以做到这一点?我已经搜索过但没有发现任何人遇到相同的问题，这令人惊讶，因为当ProgressBar显示在RecyclerView的最后一行时，我认为此功能对于我的场景和无限滚动非常有用.

Is there a different way of doing this? I have searched but not found anyone with the same problem, which is surprising as I would think this functionality would be quite useful for my scenario and for infinite scrolling, when a ProgressBar is shown in the last row of the RecyclerView.

推荐答案

您可以使用

You can use the setFullSpan method.
In this way the item will layout using all span area.

这意味着，如果方向是垂直的，则视图将具有完整宽度；如果方向是水平的，则视图将具有完整的高度.

That means, if orientation is vertical, the view will have full width; if orientation is horizontal, the view will have full height.

类似这样的东西:

public final void onBindViewHolder(RecyclerView.ViewHolder viewHolder, int position) {

    StaggeredGridLayoutManager.LayoutParams layoutParams = (StaggeredGridLayoutManager.LayoutParams) viewHolder.itemView.getLayoutParams();
    layoutParams.setFullSpan(true);
}

请注意.
它支持跨越所有列的视图，但是对于您的情况来说应该足够了.

Pay attention.
It supports views that span all the columns, but it should be enough for your case.
