Android studio - textStyle: bold does not work

I have seen similar questions but possible solutions (this was the last one that I tried) don't work. The problem is that I can not set the text as bold nor change its size, it always appears non-bold and of the same size.
I need to display #+id/contactName as bold.
<TextView
android:id="#+id/contactName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="start"
android:ellipsize="end"
android:maxLines="1"
android:overScrollMode="never"
android:paddingEnd="4dp"
android:textAppearance="#style/contactListTextPrimary"
tools:ignore="RtlSymmetry"
tools:text="Contact title" />
<style name="contactListTextPrimary" parent="#android:style/TextAppearance.Medium">
<item name="android:textColor">?android:attr/textColorPrimary</item>
<item name="android:textStyle">bold</item>
<item name="android:textSize">16sp</item>
</style>
The code above does not make the text bold, it always stays as it was before. Below is the complete styles.xml file.

You say that the contactListTextPrimary style is
<style name="contactListTextPrimary" parent="#android:style/TextAppearance.Medium">
<item name="android:textColor">?android:attr/textColorPrimary</item>
<item name="android:textStyle">bold</item>
<item name="android:textSize">16sp</item>
</style>
but in the full styles file you have just
<style name="contactListTextPrimary" parent="#android:style/TextAppearance.Medium">
<item name="android:textColor">?android:attr/textColorPrimary</item>
</style>
Make them match according to the longer version and you should see a bold font.

Have you tried setting the spinnerItemStyle as a child of actionBarWidgetTheme? Something like this:
<style name="LibetasTheme" parent="android:Theme.Holo.Light.DarkActionBar">

it does not give me errors but I don't change the text colors

Replace your Theme.Example with this one and your Skoletube.Tab.Text with TabText:
<style name="Theme.Example" parent="#style/Theme.Sherlock.Light.DarkActionBar">
<item name="actionBarItemBackground">#drawable/selectable_background_example</item>
<item name="popupMenuStyle">#style/PopupMenu.Example</item>
<item name="dropDownListViewStyle">#style/DropDownListView.Example</item>
<item name="actionBarTabStyle">#style/ActionBarTabStyle.Example</item>

<item name="actionBarStyle">#style/ActionBar.Solid.Example</item>
<item name="actionModeBackground">#drawable/cab_background_top_example</item>
<item name="actionModeSplitBackground">#drawable/cab_background_bottom_example</item>
<item name="actionModeCloseButtonStyle">#style/ActionButton.CloseMode.Example</item>
<item name="android:textColor">#color/red</item>
<!-- Light.DarkActionBar specific -->
<item name="actionBarWidgetTheme">#style/Theme.Example.Widget</item>
<item name="actionBarTabTextStyle">#style/TabText</item>
<item name="android:actionBarTabTextStyle">#style/TabText</item>
</style>
<style name="Theme.Example.TabText" parent="Widget.Sherlock.ActionBar.TabText">
<item name="android:textAppearance">#android:style/TextAppearance.Medium</item>
<item name="android:textColor">#android:color/black</item>
</style>
EDIT:
this is the proper way of doing something like this:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="YOURTHEME" parent="Theme.Sherlock.Light">
