指示表单使用Android Theme.Holo.Light的其他着色

Question

由于我不喜欢Xamarin的Android目标的黑暗主题,我使用它切换到holo light Manifest.xml:

当Button和Label显示正确的颜色时,如此创建的菜单不会:

var navMenu = new TableView {
    Intent = TableIntent.Menu,
    Root = new TableRoot {

菜单TableView 在浅灰色背景上显示白色文本.很难读.

我可以指示Xamarin.Forms一致地切换颜色吗？

要在Xamarin Forms中实现Android特定平台样式,我在我的项目中执行了以下操作:

1. 使用http://jgilfelt.github.io/android-actionbarstylegenerator/创建了我想要的UI颜色设计
2. 下载zip文件并将资源复制到Relevant Drawable文件夹中的特定于平台的Android目录.
3. 将styles_example.xml重命名为values文件夹中的Styles.xml.将Name更改为我想要的主题的名称以及我想在我的案例holo.light中使用的android holo主题基础父,我的Styles.xml的一个示例可以在下面看到.
4. 参考我的Android活动和瞧的风格.

Style.xml:

 <resources>
  <style name="Theme.Splash"
    parent="android:Theme">
    <item name="android:windowBackground"> 
    </item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsTranslucent">false</item>
    <item name="android:windowIsFloating">false</item>
    <item name="android:backgroundDimEnabled">true</item>
  </style>

    <style name="Theme.Main" parent="@android:style/Theme.Holo.Light">
        <item name="android:actionBarItemBackground">@drawable/selectable_background_example</item>
        <item name="android:popupMenuStyle">@style/PopupMenu.Example</item>
        <item name="android:dropDownListViewStyle">@style/DropDownListView.Example</item>
        <item name="android:actionBarTabStyle">@style/ActionBarTabStyle.Example</item>
        <item name="android:actionDropDownStyle">@style/DropDownNav.Example</item>
        <item name="android:actionBarStyle">@style/ActionBar.Solid.Example</item>
        <item name="android:actionModeBackground">@drawable/cab_background_top_example</item>
        <item name="android:actionModeSplitBackground">@drawable/cab_background_bottom_example</item>
        <item name="android:actionModeCloseButtonStyle">@style/ActionButton.CloseMode.Example</item>
    </style>

    <style name="ActionBar.Solid.Example" parent="@android:style/Widget.Holo.Light.ActionBar.Solid">
        <item name="android:background">@drawable/ab_solid_example</item>
        <item name="android:backgroundStacked">@drawable/ab_stacked_solid_example</item>
        <item name="android:backgroundSplit">@drawable/ab_bottom_solid_example</item>
        <item name="android:progressBarStyle">@style/ProgressBar.Example</item>
    </style>

    <style name="ActionBar.Transparent.Example" parent="@android:style/Widget.Holo.Light.ActionBar">
        <item name="android:background">@drawable/ab_transparent_example</item>
        <item name="android:progressBarStyle">@style/ProgressBar.Example</item>
    </style>

    <style name="PopupMenu.Example" parent="@android:style/Widget.Holo.Light.ListPopupWindow">
        <item name="android:popupBackground">@drawable/menu_dropdown_panel_example</item>   
    </style>

    <style name="DropDownListView.Example" parent="@android:style/Widget.Holo.Light.ListView.DropDown">
        <item name="android:listSelector">@drawable/selectable_background_example</item>
    </style>

    <style name="ActionBarTabStyle.Example" parent="@android:style/Widget.Holo.Light.ActionBar.TabView">
        <item name="android:background">@drawable/tab_indicator_ab_example</item>
    </style>

    <style name="DropDownNav.Example" parent="@android:style/Widget.Holo.Light.Spinner">
        <item name="android:background">@drawable/spinner_background_ab_example</item>
        <item name="android:popupBackground">@drawable/menu_dropdown_panel_example</item>
        <item name="android:dropDownSelector">@drawable/selectable_background_example</item>
    </style>

    <style name="ProgressBar.Example" parent="@android:style/Widget.Holo.Light.ProgressBar.Horizontal">
        <item name="android:progressDrawable">@drawable/progress_horizontal_example</item>
    </style>

    <style name="ActionButton.CloseMode.Example" parent="@android:style/Widget.Holo.Light.ActionButton.CloseMode">
        <item name="android:background">@drawable/btn_cab_done_example</item>
    </style>

  <!-- this style is only referenced in a Light.DarkActionBar based theme -->
    <style name="Theme.Example.Widget" parent="@android:style/Theme.Holo">
    </style>

</resources>

活动代码:

namespace Test.Droid
{
    [Activity(Label = "Test", ConfigurationChanges = ConfigChanges.Orientation | ConfigChanges.ScreenSize,Theme = "@style/Theme.Main")]

    public class MainActivity : AndroidActivity
    {
    }
