Android 如何在一个gridview中创建两个不同数量的列

我想制作一个具有两个不同列数的gridview

实际上，我的gridview有两列作为

fig1

，在第5位，列数应该是1列作为

fig2

我附上了我的截图，以便进一步澄清

//图1：电流输出

//图2：最终输出

---

您可以通过以下UI构造来实现这一点：构造一个垂直方向的ListView（或单列GridView），并在其中放置一个前两行有两列的GridView、一个ImageView（或其他紫色视图）和一个最后一行有两列的GridView（体育和艺术）

如果需要整行成为一列，请使用GridLayout和merge columns

尝试使用
我写了一个例子来帮助你解决问题。
结果与图2相同，但没有图像
