推荐答案

以下代码将允许您完全设置操作栏的样式.

The following code will allow you to completely style the action bar.

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="actionBarStyle">@style/Widget.AppTheme.ActionBar</item>
    <item name="actionBarTheme">@style/ThemeOverlay.AppTheme.ActionBar</item>
    <item name="actionBarPopupTheme">@style/ThemeOverlay.AppTheme.PopupMenu</item>
</style>

覆盖操作栏样式以更改背景颜色或高度.

Override the action bar style to change the background color or elevation.

<style name="Widget.AppTheme.ActionBar" parent="Widget.AppCompat.ActionBar.Solid">
    <!-- action bar background - without android prefix -->
    <item name="background">...</item>
    <!-- action bar elevation - without android prefix -->
    <item name="elevation">4dp</item>
</style>

覆盖操作栏主题以定义操作栏中所有视图的特殊行为，例如操作项、波纹背景颜色、文本颜色.

Override the action bar theme to define special behavior for all views inside the action bar such as action items, ripple background color, text color.

<style name="ThemeOverlay.AppTheme.ActionBar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <!-- title text color -->
    <item name="android:textColorPrimary">...</item>
    <!-- subtitle text color -->
    <item name="android:textColorSecondary">?android:textColorPrimary</item>
    <!-- action menu item text color -->
    <item name="actionMenuTextColor">?android:textColorPrimary</item>
    <!-- action menu item icon color -->
    <item name="colorControlNormal">?android:textColorPrimary</item>
</style>

您还可以更改弹出主题.

You can also change the popup theme.

<style name="ThemeOverlay.AppTheme.PopupMenu" parent="ThemeOverlay.AppCompat.Dark">
    <!-- popup menu background - NEVER "android:background" !!! in themes -->
    <item name="android:colorBackground">...</item>
    <!-- popup menu item text color -->
    <item name="android:textColorPrimary">...</item>
</style>

另一方面，以下代码将允许您设置窗口的样式.

On the other hand, the following code will allow you to style the window.

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- window background - NEVER "android:background" in themes !!! -->
    <item name="android:windowBackground">...</item>
    <item name="android:textColorPrimary">...</item>
    <item name="android:textColorSecondary">...</item>
</style>

您也可以直接更改操作栏上的文本颜色.但要小心！这不会影响菜单项或图标的文本颜色或波纹颜色！从长远来看，这可能不是您想要的.

You can also change text color on the action bar directly. But beware! This will not afffect text color of menu items or icons or ripple color! This is probably not what you want in the long run.

<style name="Widget.AppTheme.ActionBar" parent="Widget.AppCompat.ActionBar.Solid">
    <!-- title text color -->
    <item name="titleTextColor">?android:textColorPrimary</item>
    <!-- subtitle text color -->
    <item name="subtitleTextColor">?android:textColorSecondary</item>
</style>
