先给大家看下效果图：

MenuPopwindow:

MenuPopwindow布局：

<?xml version="1.0" enCoding="utf-8"?><linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"androID:layout_wIDth="match_parent"androID:layout_height="match_parent"androID:orIEntation="vertical"androID:paddingRight="10dp"><ListVIEwandroID:ID="@+ID/lv_topTitle_menu"androID:layout_wIDth="match_parent"androID:layout_height="wrap_content"androID:background="@mipmap/back_topTitle_menu" /></linearLayout>

Adapter中的Item布局文件：

<?xml version="1.0" enCoding="utf-8"?><linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"androID:layout_wIDth="match_parent"androID:layout_height="match_parent"androID:gravity="center"androID:orIEntation="horizontal"androID:paddingBottom="10dp"androID:paddingtop="10dp"><ImageVIEwandroID:ID="@+ID/iv_menu_item"androID:layout_wIDth="wrap_content"androID:layout_height="wrap_content"androID:layout_gravity="center_vertical"androID:layout_marginRight="10dp"androID:src="@mipmap/icon_menu_item_edit" /><TextVIEwandroID:ID="@+ID/tv_menu_item"androID:layout_wIDth="wrap_content"androID:layout_height="wrap_content"androID:layout_gravity="center_vertical"androID:text="测试"androID:textcolor="@color/black"androID:textSize="18sp" /></linearLayout>

使用：

int[] icons = {R.mipmap.icon_menu_item_edit,R.mipmap.icon_menu_item_delete};String[] texts = {"编辑","删除"};List<MenuPopwindowBean> List = new ArrayList<>();MenuPopwindowBean bean = null;for (int i = 0; i < icons.length; i++) {bean = new MenuPopwindowBean();bean.setIcon(icons[i]);bean.setText(texts[i]);List.add(bean);}MenuPopwindow pw = new MenuPopwindow(PersonalimgPlayActivity.this,List);pw.setonItemClick(myOnItemClickListener);pw.showPopupWindow(findVIEwByID(R.ID.img_top1_share));//点击右上角的那个button
