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="http://schemas.android.com/apk/res/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="http://schemas.android.com/apk/res/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="http://schemas.android.com/apk/res/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" };

@Override

public 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 {

@Override

public 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);

}

}
