　　最主要的，是自定义的Style，我们自定义一个式样，用来改变默认的Dialog样式

在values文件夹下新建一个styles.xml文件，如下。。。

<?
xml version="1.0" encoding="utf-8"
?>


<
resources
>

    
<
style 
name
="MyDialog"
 parent
="@android:Theme.Dialog"

>

        
<item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item> 
        <item name="android:windowBackground">@drawable/dialog_bg</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>


    
</
style
>


</
resources
>
