先给大家看下效果图：

menupopwindow:

public class menupopwindow extends popupwindow {
private view conentview;
private listview lvcontent;
public menupopwindow(activity context, list<menupopwindowbean> list) {
layoutinflater inflater = (layoutinflater) context

// 设置selectpicpopupwindow的view

// 设置selectpicpopupwindow弹出窗体可点击

// 刷新状态
this.update();
// 实例化一个colordrawable颜色为半透明
colordrawable dw = new colordrawable(0000000000);
// 点back键和其他地方使其消失,设置了这个才能触发ondismisslistener ，设置其他控件变化等操作

}
public void setonitemclick(adapterview.onitemclicklistener myonitemclicklistener) {

}
class myadapter extends baseadapter {
private list<menupopwindowbean> list;
private layoutinflater inflater;
public myadapter(context context, list<menupopwindowbean> list) {
inflater = layoutinflater.from(context);
this.list = list;
}
@override
public int getcount() {
return list == null ? 0 : list.size();
}
@override
public object getitem(int position) {
return list.get(position);
}
@override
public long getitemid(int position) {
return position;
}
@override
public view getview(int position, view convertview, viewgroup parent) {
holder holder = null;
if (convertview == null) {
convertview = inflater.inflate(r.layout.menu_popup_window_item, null);
holder = new holder();
holder.ivitem = (imageview) convertview.findviewbyid(r.id.iv_menu_item);
holder.tvitem = (textview) convertview.findviewbyid(r.id.tv_menu_item);
convertview.settag(holder);
} else {
holder = (holder) convertview.gettag();
}
holder.ivitem.setimageresource(list.get(position).geticon());
holder.tvitem.settext(list.get(position).gettext());
return convertview;
}
class holder {
imageview ivitem;
textview tvitem;
}
}
/**

*/
public void showpopupwindow(view parent) {
if (!this.isshowing()) {
// 以下拉方式显示popupwindow
this.showasdropdown(parent);
} else {
this.dismiss();
}
}
}

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">
<listview
android: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">
<imageview
android: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" />
<textview
android: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
