具有额外背景的Android警报对话框 [英] Android Alert Dialog with extra background

问题描述

我最近将我的应用程序迁移到了Material Design，并且在警告对话框"中偶然发现了这个问题:

I recently migrated my app to Material Design and I stumbled upon this problem with my Alert Dialogs:

我正在像这样应用对话框样式:

I'm applying the dialog style like this:

<item name="android:alertDialogTheme">@style/Theme.AlertDialog</item>

和 Theme.AlertDialog 看起来像这样:

<style name="Theme.AlertDialog" parent="Base.V14.Theme.AppCompat.Dialog">
    <item name="colorPrimary">@color/theme_primary</item>
    <item name="colorPrimaryDark">@color/theme_primary_dark</item>
    <item name="colorAccent">@color/theme_accent_dark</item>
</style>

这是在我的奇巧(Kitkat)设备上发生的，并且在棒棒糖上也可以正常工作.您能帮我摆脱这种外部背景吗?

This is happening on my Kitkat device and it works fine on Lollipop. Can you help me with getting rid of that outer background?

推荐答案

要点在这里:

<style name="Theme.AlertDialog" parent="Base.V14.Theme.AppCompat.Dialog">
    ...
    <item name="colorPrimary">@color/theme_primary</item>
    <item name="colorPrimaryDark">@color/theme_primary_dark</item>
    <item name="colorAccent">@color/theme_accent_dark</item>
    ...
    <item name="android:windowBackground">@android:color/transparent</item>
    ...
</style>
