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>         </resources>
