Can you please post Your entire code here . From the first look what i can understand is the height of the layout where you are populating the popup menu is much high . So even after populating the four items , its having enough of empty space . Change the layout_height of the layout where you are inflating the popup to wrap-content instead of using some fixed height . I hope that will solve the issue .

你能在这里发布你的全部代码吗?从第一眼看,我可以理解的是,布局弹出菜单的布局高度非常高。所以即使在填充这四个项目之后,它也有足够的空白空间。将要弹出弹出窗口的布局的layout_height更改为wrap-content而不是使用某个固定高度。我希望能解决这个问题。
