Android tabs colorcolor selector ignores state_pressed

I created my own Android theme to change the appearance of the tabs in the action bar. The problem is that the color print selector seems to ignore the state_pressed attribute, so the text color of a tab is always the same even if that tab is clicked. No problem with other states, for example state_selected is correctly recognized and the selected tab has a text color that is different from the text color of the unselected tabs.

Also, I also created a selector for the background of the tabs and it works fine with state_pressed (if the tab is clicked, the background color changes).

There are several parts to my code:

styles.xml:

<style name="Theme.MyTheme" parent="android:Theme.Holo.Light.DarkActionBar">
    <item name="android:actionBarTabStyle">@style/Theme.MyTheme.TabStyle</item>
    <item name="android:actionBarTabTextStyle">@style/Theme.MyTheme.TabTextStyle</item>
</style>

...

<style name="Theme.MyTheme.TabStyle"
       parent="@android:style/Widget.Holo.Light.ActionBar.TabView">
    <item name="android:background">@drawable/background_selector</item>
</style>

<style name="Theme.MyTheme.TabTextStyle"
       parent="@android:style/Widget.Holo.Light.ActionBar.TabText">
    <item name="android:textColor">@color/textcolor_selector</item>
</style>

      

        
        
        
      

    

background_selector.xml:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="false" android:state_pressed="false">
        <shape>
            <solid android:color="#00ff00"/>
        </shape>
    </item>

    <item android:state_selected="false" android:state_pressed="true">
        <shape>
            <solid android:color="#0000ff"/>
        </shape>
    </item>

    <item android:state_selected="true" android:state_pressed="false">
        <shape>
            <solid android:color="#ff0000"/>
        </shape>
    </item>

    <item android:state_selected="true" android:state_pressed="true">
        <shape>
            <solid android:color="#ffff00"/>
        </shape>
    </item>
</selector>

      

        
        
        
      

    

textcolor_selector.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:state_pressed="false"
          android:color="#ff0000"/>
    <item android:state_selected="true" android:state_pressed="true"
          android:color="#0000ff"/>
    <item android:state_selected="false" android:state_pressed="false"
          android:color="#ffff00"/>
    <item android:state_selected="false" android:state_pressed="true"
          android:color="#00ff00"/>
</selector>

      

        
        
        
      

    

I've tried everything without success - the state_pressed attribute seems to be ignored, but only in the textcolor_selector. Please help me figure out and solve this problem.
