activity的dialog样式设置

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

<style name="FullHeightDialog" parent="android:style/Theme.Dialog">
<item name="android:windowNoTitle">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
</style>

</resources>

上面的代码写在string.xml里面

然后在清单文件中给activity设置theme

 android:theme="@style/FullHeightDialog"  

 

ok  搞定~！！
