Android 如何修复应用程序主题

我正在开发已经开发的应用程序的新版本。现在我面临着一个奇怪的问题，不管我在xml中设置的背景颜色是什么，但当应用程序运行时，它显示的是深色的背景，有点黑

下面是styles.xml。注：colorPrimary、colorPrimaryDark、colorAccent均为绿色

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="MyTheme" parent="android:Theme.Holo.Light.Dialog">
        <!--<item name="android:alertDialogStyle">@style/CustomAlertDialogStyle</item>
        <item name="android:windowBackground">@color/transparent</item>
        <!--<item name="android:textColorPrimary">#FFFFFF</item>-->
        <item name="android:backgroundDimEnabled">false</item>
        <!--<item name="android:textColor">#FFFFFF</item>-->
        <!--<item name="android:textStyle">normal</item>-->
        <item name="android:textSize">12sp</item>-->
    </style>

    <style name="CustomAlertDialogStyle">
        <!--<item name="android:bottomBright">@color/transparent</item>-->
        <!--<item name="android:bottomDark">@color/transparent</item>-->
        <!--<item name="android:bottomMedium">@color/transparent</item>-->
        <!--<item name="android:centerBright">@color/transparent</item>-->
        <!--<item name="android:centerDark">@color/transparent</item>-->
        <!--<item name="android:centerMedium">@color/transparent</item>-->
        <!--<item name="android:fullBright">@color/transparent</item>-->
        <!--<item name="android:fullDark">@color/transparent</item>-->
        <!--<item name="android:topBright">@color/transparent</item>-->
        <!--<item name="android:topDark">@color/transparent</item>item-->
    </style>

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>

这是舱单

哇，没有看到任何人使用
开发者工具

我认为您的问题是您的
对话框的问题。
您是否尝试将对话框构造函数与
主题一起使用，如下所示：
新建AlertDialog/*.Builder*/（上下文，int主题）
请显示活动或片段的XML布局。@code Producer确定，请稍候以while@Code-学徒首先更新了问题。我确实遵循开发人员的工具。第二，这不是问题。这实际上与主题有关。整个应用程序的背景为黑色，应用程序中没有提到颜色资源。我已经仔细检查过了，您可以添加用于显示对话框的Java代码吗？您可以应用我为
对话框
建议的构造函数，如下所示：
dialog dialog=newdialog（this，R.style.MyTheme）；//如果主题正确
，则不会改变活动的背景。为什么应用程序主题在这里不起作用？能否添加您的
Manifest.xml
？
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Text"
    android:textSize="40dp"
    android:textStyle="bold"
    android:layout_centerInParent="true"/>

  </RelativeLayout>

Dialog dialog = new Dialog(this);
            dialog.setContentView(R.layout.consumer_welcome_dialogue);
            dialog.show();
            Window window = dialog.getWindow();
            window.setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
