Question

I have tried everything and I can’t get this to work. I have read all related posts on this topic, but havent found a working solution!

I wanna change the tab bar text size using ActionBarSherlock. I’ve managed to change the actionbar, but not the tabs text underneath (or the tabs themselves for that matter).

In styles.xml I have (one of many tries):

<style name="ANM_Theme" parent="Theme.Sherlock">
<item name="actionBarTabTextStyle">@style/Theme_ActionBarText</item>
<item name="android:actionBarTabTextStyle">@style/Theme_ActionBarText</item>

<style name="Theme_ActionBarText" parent="Widget.Sherlock.ActionBar.TabText">
<item name="android:textColor">#fff</item>
<item name="android:textSize">6sp</item>

And in my activity i set

public static int THEME = R.style.ANM_Theme;

And then

setTheme(THEME);

Before

super.onCreate(savedInstanceState);

EDIT:

Just realized that when you are using Tabs+Pager you don’t get the 4.0 look on the tabs! That clarifies why I can’t customize the tabs through the ActionBarSherlock theme.. I was trying on a 4.1 device. Downloaded the ActionBarSherlock demo app and got the same results..

Anyone know how to fix it?

public class MainActivity extends SherlockFragmentActivity {
ViewPager  mViewPager;
TabsAdapter mTabsAdapter;

Button testButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ActionBar bar = getSupportActionBar();
    bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    mViewPager = (ViewPager)findViewById(R.id.pager);

    // Add the tabs
    mTabsAdapter = new TabsAdapter(this, bar, mViewPager);
    mTabsAdapter.addTab(bar.newTab().setText("First"),
            FragmentA.class, null);
    mTabsAdapter.addTab(bar.newTab().setText("Second"),
            FragmentB.class, null);
    mTabsAdapter.addTab(bar.newTab().setText("Third"),
            FragmentC.class, null);

    setTitle(R.string.app_name);

    if (savedInstanceState != null) {
        bar.setSelectedNavigationItem(savedInstanceState.getInt("tab"));
    }
}

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("tab", getSupportActionBar().getSelectedNavigationIndex());
}

@Override
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {

    menu.add("Refresh")
        .setIcon(R.drawable.ic_action_refresh)
        .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);

    SubMenu subMenu1 = menu.addSubMenu("Menu");
    subMenu1.add("Sample");
    subMenu1.add("Items");
    subMenu1.add("In menu");

    MenuItem subMenu1Item = (MenuItem) subMenu1.getItem();
    subMenu1Item.setIcon(R.drawable.ic_action_overflow);
    subMenu1Item.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS | MenuItem.SHOW_AS_ACTION_WITH_TEXT);

    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item) {
    String itemTitle  = (String) item.getTitle();

        if(!itemTitle.equals("Menu")){
            Toast toast = Toast.makeText(getApplicationContext(), itemTitle+" pressed", Toast.LENGTH_SHORT);
            toast.show();
        }


    if(item.getItemId() == android.R.id.home){
        getSupportFragmentManager().popBackStackImmediate();
    }
    return super.onOptionsItemSelected(item);
