Anndroid:自定义Menu(TabMenu)

本文来自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:[email protected]),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:

Anndroid:自定义Menu(TabMenu)_第1张图片

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:

[xhtml] view plain copy print ?
  1. <?xml version="1.0" encoding="utf-8"?>  
  2. <set xmlns:android="http://schemas.android.com/apk/res/android">  
  3.     <translate android:fromYDelta="100%p" android:toYDelta="0" android:duration="1000" />  
  4.     <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="1000" />  
  5. </set>   

新建文件popup_exit.xml:

[xhtml] view plain copy print ?
  1. <?xml version="1.0" encoding="utf-8"?>  
  2. <set xmlns:android="http://schemas.android.com/apk/res/android">  
  3.     <translate android:fromYDelta="0" android:toYDelta="100%p" android:duration="1000" />  
  4.     <alpha android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="1000" />  
  5. </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:

[xhtml] view plain copy print ?
  1. <?xml version="1.0" encoding="utf-8"?>  
  2. <LinearLayout android:id="@+id/LinearLayout01"  
  3.     android:layout_width="fill_parent" android:layout_height="fill_parent"  
  4.     xmlns:android="http://schemas.android.com/apk/res/android">  
  5.     <TextView android:id="@+id/TextView01" android:layout_height="wrap_content"  
  6.         android:layout_width="fill_parent" android:text="扩展Menu----hellogv"></TextView>  
  7. </LinearLayout>
