android RecyclerView 简单实现横竖布局穿插

RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
GridLayoutManager gridLayoutManager = new GridLayoutManager(getContext() ,2);
//todo 这个属性很重要，可以直接实现上图的效果
gridLayoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup(){
@Override
public int getSpanSize(int position) {
if(position % 3 == 0) return 2;
return 1;
}
});
recyclerView.setLayoutManager(gridLayoutManager);
recyclerView.setAdapter(adapte);
