activity中初始化配置:

//在这里弹出dialogFragment对话框
if (!newFragment.isAdded()) {//DialogFragment.show()内部调用了FragmentTransaction.add()方法，所以调用DialogFragment.show()方法时候也可能
   FragmentManager manager = getFragmentManager();
   FragmentTransaction ft = manager.beginTransaction();
   ft.add(newFragment, "dialog");
   ft.commit();
}

dialog样式:

     <style name="DialogStyle">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:background">@android:color/background_light</item>
        <item name="android:windowFullscreen">true</item>
         <item name="android:windowBackground"> @android:color/transparent </item>
         <item name="android:backgroundDimEnabled">false</item>
</style>
