在android

Question

StaggeredGridLayoutManager似乎不允许自定义单元格宽度或跨越多个列（垂直方向除外）以进行垂直方向。

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StaggeredGridLayoutManager？

Answer 1

您可以使用$ cat foo 1 1 1 2 2 3 而不是StaggeredGridLayoutManager。要在行中使用不同的列数，您必须覆盖setSpanSizeLookup。

示例：

GridLayoutManager

请注意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 } } }); ＆lt; = spanSize

Answer 2

好吧，我找到了解决方案！解决方案是： -

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);
            }
        });
