自定義menu

3 快要過(guò)年了，在這里先祝廣大的技術(shù)宅兔年快樂(lè)！
用過(guò)UCWEB-Android版的人都應(yīng)該對(duì)其特殊的menu有印象，把menu做成Tab-Menu(支持分頁(yè)的Menu)，可以容納比Android傳統(tǒng)的menu更豐富的內(nèi)容(Android的menu超過(guò)6項(xiàng)則縮略在[更多]里)，本文參考網(wǎng)上的例子(作者:CoffeeCole,email:longkefan@foxmail.com),對(duì)例子進(jìn)行簡(jiǎn)化以及封裝，使其作為一個(gè)復(fù)合控件融入自己的framework。

先來(lái)看看本文程序運(yùn)行的效果：

TabMenu本身就是一個(gè)PopupWindow，PopupWindow上面放了兩個(gè)GridView,第一個(gè)GridView就是分頁(yè)標(biāo)簽，位于PopupWindow的頂部，第二個(gè)GridView是菜單，位于PopupWindow的主體。為了實(shí)現(xiàn)PopupWindow的彈出/退出的動(dòng)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：

view plaincopyprint?

<?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>

<?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：

view plaincopyprint?

<?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>

<?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：
view plaincopyprint?

<?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(kuò)展Menu----hellogv"></TextView>  </LinearLayout>

<?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(kuò)展Menu----hellogv"></TextView></LinearLayout>
TabMenu的封裝類TabMenu.java的源碼如下：
