import android.widget.toast;

import java.util.arraylist;

public class mainactivity extends appcompatactivity {
 private button button;
 private popupwindow kindspopupwindow;

 @override
 protected void oncreate(bundle savedinstancestate) {
  super.oncreate(savedinstancestate);
  setcontentview(r.layout.activity_main);
  button = (button) findviewbyid(r.id.button);
  button.setonclicklistener(new view.onclicklistener() {
   @override
   public void onclick(view v) {
    getkindpopupwindow();
   }
  });
 }

 private void getkindpopupwindow() {
  final arraylist kindslist = new arraylist();
  kindslist.add("全部分类");
  kindslist.add("今日上线");
  kindslist.add("美食");
  kindslist.add("酒店");
  kindslist.add("旅游");
  layoutinflater inflater = layoutinflater.from(this);
  // 引入窗口配置文件
  view view = inflater.inflate(r.layout.pop_local_kind, null);
  // 创建popupwindow对象
  kindspopupwindow = new popupwindow(view, linearlayout.layoutparams.wrap_content, linearlayout.layoutparams.wrap_content, false);
  //设置popupwindow宽
  kindspopupwindow.setwidth(button.getwidth());
  listview listview = (listview) view.findviewbyid(r.id.list);
  popadapter adapter = new popadapter(mainactivity.this,kindslist);
  listview.setadapter(adapter);

  // 需要设置一下此参数，点击外边可消失
  kindspopupwindow.setbackgrounddrawable(new bitmapdrawable());
  //设置点击窗口外边窗口消失
  kindspopupwindow.setoutsidetouchable(true);
  // 设置此参数获得焦点，否则无法点击
  kindspopupwindow.setfocusable(true);
  //设置popupwindow显示位置
  kindspopupwindow.showasdropdown(button);
  listview.setonitemclicklistener(new adapterview.onitemclicklistener() {
   @override
   public void onitemclick(adapterview<?> adapterview, view view, int i, long l) {
    toast.maketext(mainactivity.this,i+"pop",toast.length_short).show();
    button.settext(kindslist.get(i).tostring());
    kindspopupwindow.dismiss();
   }
  });
 }

 //pop适配器
 private class popadapter extends baseadapter {
  private context context;
  private arraylist<string> list;

  public popadapter(context context, arraylist<string> list) {
   this.context = context;
   this.list = list;
  }

  @override
  public int getcount() {
   if (list==null||list.size()==0){
    return 0;
   }
   return list.size();
  }

  @override
  public object getitem(int i) {
   return list.get(i);
  }

  @override

   return i;
  }

  public view getview(int i, view convertview, viewgroup viewgroup) {
   viewholder holder = null;
   if(convertview==null){
    holder = new viewholder();
    convertview = layoutinflater.from(context).inflate(r.layout.item_pop_local_kind, null);
    holder.textview = (textview) convertview.findviewbyid(r.id.item_text);
    convertview.settag(holder);
   }else{
    holder=(viewholder)convertview.gettag();
   }
   holder.textview.settext(list.get(i).tostring());
   return convertview;
  }
  private class viewholder {
   textview textview;
  }
 }
}

2.首页布局

<?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"
 >

 <button
  android:id="@+id/button"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="show popupwindow" />
</linearlayout>

3.popupwindow布局，可根据情况自行布局，这里是demo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:background="#ffffff">

 <listview
  android:id="@+id/list"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:background="#888888">
 </listview>
</linearlayout>

4.popupwindow条目布局

<?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:background="@color/white">
 <textview
  android:id="@+id/item_text"
  android:layout_width="match_parent"
  android:layout_height="40dp"
  android:gravity="center"
  android:text="pop"
  android:textcolor="#f08e1f"
