先给大家看下效果图：

MenuPopwindow:

package com.cloudeye.android.cloudeye.view;import android.app.Activity;import android.content.Context;import android.graphics.drawable.ColorDrawable;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.AdapterView;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.ListView;import android.widget.PopupWindow;import android.widget.TextView;import com.cloudeye.android.cloudeye.R;import com.cloudeye.android.cloudeye.base.MenuPopwindowBean;import java.util.List;/*** Created by 袁磊 on 2016/10/26.*/public class MenuPopwindow extends PopupWindow {private View conentView;private ListView lvContent;public MenuPopwindow(Activity context, List<MenuPopwindowBean> list) {LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);conentView = inflater.inflate(R.layout.menu_popup_window, null);lvContent = (ListView) conentView.findViewById(R.id.lv_toptitle_menu);lvContent.setAdapter(new MyAdapter(context, list));int h = context.getWindowManager().getDefaultDisplay().getHeight();int w = context.getWindowManager().getDefaultDisplay().getWidth();// 设置SelectPicPopupWindow的Viewthis.setContentView(conentView);// 设置SelectPicPopupWindow弹出窗体的宽this.setWidth(w / 3-30);// 设置SelectPicPopupWindow弹出窗体的高this.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);// 设置SelectPicPopupWindow弹出窗体可点击this.setFocusable(true);this.setOutsideTouchable(true);// 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this.setBackgroundDrawable(dw);// mPopupWindow.setAnimationStyle(android.R.style.Animation_Dialog);// 设置SelectPicPopupWindow弹出窗体动画效果this.setAnimationStyle(R.style.AnimationPreview);}public void setOnItemClick(AdapterView.OnItemClickListener myOnItemClickListener) {lvContent.setOnItemClickListener(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;}@Overridepublic int getCount() {return list == null ? 0 : list.size();}@Overridepublic Object getItem(int position) {return list.get(position);}@Overridepublic long getItemId(int position) {return position;}@Overridepublic 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;}}/*** 显示popupWindow** @param parent*/public void showPopupWindow(View parent) {if (!this.isShowing()) {// 以下拉方式显示popupwindowthis.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"><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
