android中不同单元格宽度的RecyclerView网格的LayoutManager

StaggedGridLayoutManager似乎不允许为垂直方向自定义单元格宽度或跨多列（全跨除外）

如何创建如上图所示的布局？在这种情况下，什么是完美的布局管理器。。。GridLayoutManager或StaggedGridLayoutManager？

您可以使用

GridLayoutManager

而不是

StaggedGridLayoutManager

。要在行中有不同的列计数，必须重写

例如：

GridLayoutManager gridLayoutManager = new GridLayoutManager(getAppContext(), spanCount);
gridLayoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
    @Override
    public int getSpanSize(int position) {
        //define span size for this position
        //for example, if you have 2 column per row, you can implement something like that:
        if(position == youRule) {
            return 2; //item will take 2 column (full row size)
        } else {
            return 1; //you will have 2 rolumn per row
        }
    }
});

注意

spanSize

好吧，我已经解决了！解决办法是：-

GridLayoutManager layoutManager = new GridLayoutManager(this, 2);
        layoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
            @Override
            public int getSpanSize(int position) {
//                if (position % 3 == 0) {
//                    Log.e("TAG", "Position: " + position +" position % 3= " + position % 3 + " return 2");
//                    return 2;
//                } else {
//                    Log.e("TAG", "Position: " + position +" position % 3= " + position % 3 + " return 1");
//                    return 1;
//                }
                if (position % 3 == 0 || position % 3 == 1) {
                    Log.e("TAG", "Position: " + position +" position % 3= " + position % 3 + " return 1");
                    return 1;
                } else {
                    Log.e("TAG", "Position: " + position +" position % 3= " + position % 3 + " return 2");
                    return 2;
                }
//                return (3 - position % 3);
            }
        });

我已经试过了，但没有得到准确的输出。这是我的代码：

GridLayoutManager-layoutManager=newgridlayoutmanager（这个，3）；layoutManager.SetPansizeLookup（新GridLayoutManager.SpanSizeLookup（）{@Override public int getSpanSize（int position）{if（position%2==0）{return 2；}否则{return 1；}//return（3-position%3）；}         });
