使用popupwindow设计出popupmenu效果的菜单

1、popupwindow的布局文件：menu_layout.xml

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ListView android:id="@+id/listView" android:layout_width="80dp" android:layout_height="wrap_content" android:background="@drawable/rectangle" android:divider="#d8d8d8" android:dividerHeight="1px" > </ListView></RelativeLayout>

2、菜单项的布局文件：menu_item.xml

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical"> <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="30dp"android:layout_centerInParent="true"android:gravity="center" android:textColor="#FFFFFF" android:textSize="10.5sp" android:text="dsss"/></RelativeLayout>

3、popupwindow的背景设置：rectangle.xml

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="" android:shape="rectangle" ><!– 定义使用渐变色填充 –> <!– <gradient android:angle="270" android:endColor="#000000" android:startColor="#000000" /> –> <!– 定义几何形状的内边距 –> <padding android:bottom="2dp" android:left="2dp" android:right="2dp" android:top="2dp" /> <!– 定义几何形状的大小 –> <size android:height="60dp" android:width="30dp" /> <!– 定义使用单种颜色填充 –> <solid android:color="#000000"/> <!– 绘制边框 –> <stroke android:width="1px" android:color="#f4b00f"/></shape>

4、Activity

package com.example.httptest;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import android.app.Activity;import android.graphics.drawable.BitmapDrawable;import android.os.Bundle;import android.util.Log;import android.view.Gravity;import android.view.View;import android.view.ViewGroup;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.Button;import android.widget.ListAdapter;import android.widget.ListView;import android.widget.PopupWindow;import android.widget.SimpleAdapter;public class PopupWindowActivity extends Activity {private PopupWindow popupWindow;private View parent;/** 菜单弹出来时候的菜单项文字 */private String[] names = { "编辑相册", "删除相册","删除相片" };@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);Button bn = (Button) findViewById(R.id.bn);/** PopupWindow的界面 */View contentView = getLayoutInflater().inflate(R.layout.menu_layout, null);/** 列表布局界面 */ListView listView = (ListView) contentView.findViewById(R.id.listView);/** 设置网格布局的适配器 */listView.setAdapter(getAdapter());/** 设置网格布局的菜单项点击时候的Listener */listView.setOnItemClickListener(new ItemClickListener());/** 初始化PopupWindow */popupWindow = new PopupWindow(contentView,ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT);//popupWindow.popupWindow.setFocusable(true);// 取得焦点popupWindow.setBackgroundDrawable(new BitmapDrawable());/** 设置PopupWindow弹出和退出时候的动画效果 *///popupWindow.setAnimationStyle(R.style.animation);parent = this.findViewById(R.id.main);}private final class ItemClickListener implements OnItemClickListener {@Overridepublic void onItemClick(AdapterView<?> parent, View view, int position,long id) {if (popupWindow.isShowing()) {popupWindow.dismiss();// 关闭}}}/** 返回网格布局的适配器 */private ListAdapter getAdapter() {List<HashMap<String, Object>> data = new ArrayList<HashMap<String, Object>>();for (int i = 0; i < names.length; i++) {HashMap<String, Object> item = new HashMap<String, Object>();item.put("name", names[i]);data.add(item);}SimpleAdapter simpleAdapter = new SimpleAdapter(this, data,R.layout.menu_item, new String[] { "name" },new int[] { R.id.textView });return simpleAdapter;}public void openPopWindow(View v) {/** 设置PopupWindow弹出后的位置 *///popupWindow.showAtLocation(parent, Gravity.BOTTOM, 0, 0);int[] location = new int[2]; v.getLocationOnScreen(location); Log.v("li","按钮的位置："+location[0]+","+location[1]); //popupWindow.showAsDropDown(v); int w = location[0]-10; //popupWindow.getHeight() int h = location[1]+70; Log.v("li","popupwindow的位置："+w+","+h); popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, location[0] + 25, location[1] + 67);}}
