Question

我正在开发已开发的应用程序的新版本。现在我面临这个奇怪的问题，无论我在xml中设置的背景颜色，但是当app运行时它显示深色背景，有点黑。

这是styles.xml。注意colorPrimary，colorPrimaryDark，colorAccent是绿色的。

<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>

这是它的外观。基本上这是活动中的对话框。

以下是它应该如何而不是上面的图像。 android studio xml预览的屏幕截图

请帮帮我！

修改

这是xml的活动和片段

活动的xml

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme">

    <android.support.v7.widget.Toolbar
        android:id="@+id/consumer_toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/AppTheme" />
    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="fixed"
        app:tabGravity="fill" />
</android.support.design.widget.AppBarLayout>

<android.support.v4.view.ViewPager
    android:id="@+id/viewpager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:theme="@style/AppTheme"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

Fragment的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"
tools:context=".activities.test.OneFragment">

<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>

这里是对话的java代码。

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);

这是带有背景图片的xml预览。我只是添加backgroud="drawable/backgound" 它应该出现在这样的应用程序中，但它不显示背景，而是显示黑色背景

哇，没有看到有人使用Developers Tools ......

我认为您的问题是Dialog的问题。您是否尝试将对话构造函数与Theme？一起使用？，如下所示：new AlertDialog/*.Builder*/(Context context, int theme);
