本文来自[http://blog.csdn.net/hellogv/](http://blog.csdn.net/hellogv/) ，引用必须注明出处！        快要过年了，在这里先祝广大的技术宅兔年快乐！        用过UCWEB-Android版的人都应该对其特殊的menu有印象，把menu做成Tab-Menu(支持分页的Menu)，可以容纳比Android传统的menu更丰富的内容(Android的menu超过6项则缩略在[更多]里)，本文参考网上的例子(作者:CoffeeCole,email:longkefan@foxmail.com),对例子进行简化以及封装，使其作为一个复合控件融入自己的framework。 先来看看本文程序运行的效果：  TabMenu本身就是一个PopupWindow，PopupWindow上面放了两个GridView,第一个GridView就是分页标签，位于PopupWindow的顶部，第二个GridView是菜单，位于PopupWindow的主体。为了实现PopupWindow的弹出/退出的动画效果，本文使用了以下代码： 在工程的res文件夹里添加anim子目录，再新建文件popup_enter.xml： ~~~ <?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromYDelta="100%p" android:toYDelta="0" android:duration="1000" /> <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="1000" /></set> ~~~ 新建文件popup_exit.xml： ~~~ <?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromYDelta="0" android:toYDelta="100%p" android:duration="1000" /> <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="1000" /></set> ~~~ 在工程的values文件夹里新建文件popup_animation.xml： ~~~ <?xml version="1.0" encoding="utf-8"?>  <resources>         <style name="PopupAnimation" parent="android:Animation">         <item name="android:windowEnterAnimation">@anim/popup_enter</item>          <item name="android:windowExitAnimation">@anim/popup_exit</item>       </style>  </resources>  ~~~       main.xml的源码如下： ~~~ <?xml version="1.0" encoding="utf-8"?><LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <TextView android:id="@+id/TextView01" android:layout_height="wrap_content" android:layout_width="fill_parent" android:text="扩展Menu----hellogv"></TextView></LinearLayout> ~~~ TabMenu的封装类TabMenu.java的源码如下： ~~~ package com.testTabMenu;import android.content.Context;import android.graphics.Color;import android.graphics.drawable.ColorDrawable;import android.view.Gravity;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.GridView;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.PopupWindow;import android.widget.TextView;import android.widget.AdapterView.OnItemClickListener;import android.widget.LinearLayout.LayoutParams;public class TabMenu extends PopupWindow{ private GridView gvBody, gvTitle;
