推荐答案

您可以使用GridLayoutManager.

You could use GridLayoutManager.

GridLayoutManager manager = new GridLayoutManager(this, 2, GridLayoutManager.VERTICAL, false);

manager.setSpanSizeLookup(
    new GridLayoutManager.SpanSizeLookup() {
        @Override
        public int getSpanSize(int position) {
             // 2 column size for first row
             return (position == 0 ? 2 : 1);
        }
    });

在这里，我们正在创建具有2个网格列的GridLayoutManager.然后仅将第一行的跨度设置为2.

Here we are creating a GridLayoutManager with 2 grid columns. Then only for the first row, we are setting the span size to 2.
