定义Dialog的样式（主题）：

<?xml version="1.0" encoding="utf-8"?>  
<resources>  
   
    <!-- 定义对话框样式 -->  
    <style name="Dialog" parent="android:style/Theme.Dialog">  
        <item name="android:windowBackground">@null</item>  
        <item name="android:windowNoTitle">true</item>  
        <item name="android:windowIsFloating">true</item>  
    </style>
