更改文本顏色和動作條

Question

的大小我嘗試通過風格的資源來改變文字的顏色和我的動作條的大小：

<?xml version="1.0" encoding="utf-8"?> 
<resources xmlns:android="http://schemas.android.com/apk/res/android"> 

    <style name="Theme.Example3" parent="@android:style/Theme.Holo.Light"> 
     <item name="android:actionBarItemBackground">@drawable/selectable_background_example3</item> 
     <item name="android:popupMenuStyle">@style/PopupMenu.Example3</item> 
     <item name="android:dropDownListViewStyle">@style/DropDownListView.Example3</item> 
     <item name="android:actionBarTabStyle">@style/ActionBarTabStyle.Example3</item> 
     <item name="android:actionDropDownStyle">@style/DropDownNav.Example3</item> 
     <item name="android:actionBarStyle">@style/ActionBar.Solid.Example3</item> 
     <item name="android:actionModeBackground">@drawable/cab_background_top_example3</item> 
     <item name="android:actionModeSplitBackground">@drawable/cab_background_bottom_example3</item> 
     <item name="android:actionModeCloseButtonStyle">@style/ActionButton.CloseMode.Example3</item> 
    </style> 

    <style name="ActionBar.Solid.Example3" parent="@android:style/Widget.Holo.Light.ActionBar.Solid"> 
     <item name="android:background">@drawable/ab_solid_example3</item> 
     <item name="android:backgroundStacked">@drawable/ab_stacked_solid_example3</item> 
     <item name="android:backgroundSplit">@drawable/ab_bottom_solid_example3</item> 
     <item name="android:progressBarStyle">@style/ProgressBar.Example3</item> 
    </style> 

    <style name="Theme.Example3.ActionBar.Solid.Example3.TitleTextStyle" parent="@android:style/TextAppearance.Medium"> 
     <item name="android:textSize">20sp</item> 
     <item name="android:textColor">@color/white</item> 
    </style> 

    <style name="ActionBar.Transparent.Example3" parent="@android:style/Widget.Holo.Light.ActionBar"> 
     <item name="android:background">@drawable/ab_transparent_example3</item> 
     <item name="android:progressBarStyle">@style/ProgressBar.Example3</item> 
    </style> 

    <style name="PopupMenu.Example3" parent="@android:style/Widget.Holo.Light.ListPopupWindow"> 
     <item name="android:popupBackground">@drawable/menu_dropdown_panel_example3</item> 
    </style> 

    <style name="DropDownListView.Example3" parent="@android:style/Widget.Holo.Light.ListView.DropDown"> 
     <item name="android:listSelector">@drawable/selectable_background_example3</item> 
    </style> 

    <style name="ActionBarTabStyle.Example3" parent="@android:style/Widget.Holo.Light.ActionBar.TabView"> 
     <item name="android:background">@drawable/tab_indicator_ab_example3</item> 
    </style> 

    <style name="DropDownNav.Example3" parent="@android:style/Widget.Holo.Light.Spinner"> 
     <item name="android:background">@drawable/spinner_background_ab_example3</item> 
     <item name="android:popupBackground">@drawable/menu_dropdown_panel_example3</item> 
     <item name="android:dropDownSelector">@drawable/selectable_background_example3</item> 
    </style> 

    <style name="ProgressBar.Example3" parent="@android:style/Widget.Holo.Light.ProgressBar.Horizontal"> 
     <item name="android:progressDrawable">@drawable/progress_horizontal_example3</item> 
    </style> 

    <style name="ActionButton.CloseMode.Example3" parent="@android:style/Widget.Holo.Light.ActionButton.CloseMode"> 
     <item name="android:background">@drawable/btn_cab_done_example3</item> 
    </style> 

    <!-- this style is only referenced in a Light.DarkActionBar based theme --> 
    <style name="Theme.Example3.Widget" parent="@android:style/Theme.Holo"> 
     <item name="android:popupMenuStyle">@style/PopupMenu.Example3</item> 
     <item name="android:dropDownListViewStyle">@style/DropDownListView.Example3</item> 
    </style> 

</resources> 

以上style.xml包含下面的代碼的一部分，它應該改變文字顏色和大小，但它在我的操作欄上沒有發生任何事情：

<style name="Theme.Example3.ActionBar.Solid.Example3.TitleTextStyle" parent="@android:style/TextAppearance.Medium"> 
     <item name="android:textSize">20sp</item> 
     <item name="android:textColor">@color/white</item> 
    </style> 

什麼是錯？

謝謝！

Answer 1

<item name="android:titleTextStyle">@style/Theme.Example3.ActionBar.Solid.Example3.TitleTextStyle</item> 

在<style name="ActionBar.Solid.Example3">

Answer 2

問題缺少的是你需要的風格第三塊從款式的第二塊內鏈接：

<style name="ActionBar.Solid.Example3" parent="@android:style/Widget.Holo.Light.ActionBar.Solid"> 
    <item name="android:background">@drawable/ab_solid_example3</item> 
    <item name="android:backgroundStacked">@drawable/ab_stacked_solid_example3</item> 
    <item name="android:backgroundSplit">@drawable/ab_bottom_solid_example3</item> 
    <item name="android:progressBarStyle">@style/ProgressBar.Example3</item> 

    <item name="android:titleTextStyle">@style/Theme.Example3.ActionBar.Solid.Example3.TitleTextStyle</item> 

</style>
