用過UCWEB-Android版的人都應該對其特殊的menu有印象，把menu做成Tab-Menu(支持分頁的Menu)，可以容納比Android傳統的menu更豐富的內容(Android的menu超過6項則縮略在[更多]里)，本文參考網上的例子(作者:CoffeeCole,email:longkefan@foxmail.com),對例子進行簡化以及封裝，使其作為一個復合控件融入自己的framework。

先來看看本文程序運行的效果：



TabMenu本身就是一個PopupWindow，PopupWindow上面放了兩個GridView,第一個GridView就是分頁標簽，位于PopupWindow的頂部，第二個GridView是菜單，位于PopupWindow的主體。為了實現PopupWindow的彈出/退出的動畫效果，本文使用了以下代碼：

在工程的res文件夾里添加anim子目錄，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文件夾里新建文件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的源碼如下：

    <?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="擴展Menu----hellogv"></TextView>  
</LinearLayout>
