推荐答案

请确保创建对话框引用您的自定义主题：

Be sure to create your Dialog referencing your custom theme:

Dialog dialog = new Dialog(this, R.style.MyDialogTheme);

您的自定义主题需要填充屏幕，并禁止一对夫妇的<一href="https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/themes.xml">Android框架默认的：

Your custom theme needs to fill the screen and disable a couple of Android framework defaults:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="MyDialogTheme" parent="android:Theme.Dialog">
        <!-- Fill the screen -->
        <item name="android:layout_width">fill_parent</item>
        <item name="android:layout_height">fill_parent</item>

        <!-- No backgrounds, titles or window float -->
        <item name="android:windowBackground">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">false</item>      

        <!-- Just to prove it's working -->
        <item name="android:background">#ff0000</item>
    </style>

</resources>
