I have the same issue. did you found a solution?

[icastell]

I have the same issue. In trying it with ActionBarSherlock

[icastell]

OK. I fixed it. In my onCreate method before to call super.onCreate a set the theme to the AppThemeLight, as I show below:

@Override
protected void onCreate(Bundle savedInstanceState) {

    setTheme(R.style.AppThemeLight);

    super.onCreate(savedInstanceState);
}

I had this issue too but just removed my comment as I found my mistake. I used the Actionbarsherlock Theme and added the values for TextAppearence and Slider to my custom theme but forgot to add it to the theme in my values-v11 folder... Maybe you all check your configuration too.
