Question

我在我的应用程序中使用了三个对话框，一个对话框片段中一个DatePickerDialog，一个通过Alertdialog自定义布局的dialogfragment和一个没有dialogfragment的Alertdialog。我的dateopicker对话框看起来像这样。注意标题部分完全是橙色的。

我的第二个对话框片段的标题部分没有覆盖我想要的整个窗口上部。

这是我的style.xml的相关部分

 <style name="ScheduleCompareTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/primaryColor</item>
    <item name="colorPrimaryDark">@color/primaryDarkColor</item>
    <item name="colorAccent">@color/primaryLightColor</item>
    <item name="android:dialogTheme">@style/ScheduleCompareDialogTheme</item>
    <item name="android:alertDialogTheme">@style/ScheduleCompareDialogTheme</item>
</style>

<style name="ScheduleCompareDialogTheme">
    <item name="android:windowTitleStyle">@style/ScheduleCompareDialogTitle</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowCloseOnTouchOutside">false</item>
    <item name="android:buttonBarButtonStyle">@style/Widget.MaterialComponents.Button.TextButton</item>
</style>

<style name="ScheduleCompareDialogTitle">
    <item name="android:background">@color/primaryLightColor</item>
    <item name="android:textAppearance">@style/DialogWindowTitleText</item>
</style>

<style name="DialogWindowTitleText">
    <item name="android:textColor">@color/primaryTextColor</item>
    <item name="android:textSize">24sp</item>
</style>

第一部分是我的基本主题，第二部分是用于对话框和警报对话框的样式，第三部分是dialogtitle，第四部分是标题文本。样式有效，但是总标题区域的背景以某种方式不是橙色。从第二张图片来看，我假设应用了一些标准填充，因此我将style name="ScheduleCompareDialogTheme"中的填充设置为0dp。这产生了以下效果。

因此它有效，但仅适用于toppadding。将paddingLeft和paddingRight显式设置为0 dp不会产生任何结果。

在Internet上搜索时，我发现使用android:topDark有什么用，但这也没有效果。

有人知道如何扩展橙色矩形以覆盖整个顶部区域吗？

另外，我想提一下datepicker对话框已被设置为样式，就像使用基本主题显示的那样。

编辑： 这是定制对话框的布局文件。我删除了一些未在图片中显示的代码，但是当拥有更多权限的人使用该应用程序时会使用这些代码。

END EDIT

设置AlertDialog的样式可在标题背景周围保留空白
