Android：在FragmentActivity中更改Tab的文本颜色

我想修改以下“我的标签”的文本颜色：（ACCUEIL和LA UNE）（现在为黑色）。

我不知道该怎么做。

这是FragmentActivity的代码：

package com.app.myapp.MainFragment;

import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.FragmentTransaction;
import android.content.Intent;
import android.graphics.Color;
import android.graphics.Typeface;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.view.Gravity;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.TextView;

import com.app.myapp.R;
import com.app.myapp.activities.Recherche_act;

public class TabMainFragment extends FragmentActivity implements ActionBar.TabListener {

    private ViewPager viewPager;
    private TabMainFragmentAdapter mAdapter;
    private ActionBar actionBar;
    // Tab titles
    private String[] tabs = { "ACCUEIL", "A LA UNE" };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Typeface parade = Typeface.createFromAsset(getAssets(), "fonts/parade.ttf");

        getActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM); 
        getActionBar().setCustomView(R.layout.actionbar);

        TextView title = (TextView) findViewById(R.id.action_bar_title);
        title.setTypeface(parade);
        title.setTextSize(23);
        title.setGravity(Gravity.CENTER_VERTICAL);
        title.setTextColor(Color.WHITE);

        setContentView(R.layout.main_tab_detail_frag);

        //Typeface robotolight = Typeface.createFromAsset(getAssets(), "fonts/Roboto-Light.ttf");

        ActionBar bar = getActionBar();
        bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#E64260")));

        // Initilization
        viewPager = (ViewPager) findViewById(R.id.pager);
        actionBar = getActionBar();
        mAdapter = new TabMainFragmentAdapter(getSupportFragmentManager());

        viewPager.setAdapter(mAdapter);
        actionBar.setHomeButtonEnabled(false);
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);        

        // Adding Tabs
        for (String tab_name : tabs) {
            actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this));
        }

        /**
         * on swiping the viewpager make respective tab selected
         * */
        viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

            @Override
            public void onPageSelected(int position) {
                // on changing the page
                // make respected tab selected
                actionBar.setSelectedNavigationItem(position);
            }

            @Override
            public void onPageScrolled(int arg0, float arg1, int arg2) {
            }

            @Override
            public void onPageScrollStateChanged(int arg0) {
            }
        });


    }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction ft) {
    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        // on tab selected
        // show respected fragment view
        viewPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu items for use in the action bar
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.main, menu);
        return super.onCreateOptionsMenu(menu);
    }


    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle presses on the action bar items
        switch (item.getItemId()) {
            case R.id.action_choix_categorie:

                Intent myIntent = new Intent(TabMainFragment.this, Recherche_act.class);
                TabMainFragment.this.startActivity(myIntent);
                overridePendingTransition(R.anim.slide_in_up, R.anim.slide_out_up);

                return true;

            default:
                return super.onOptionsItemSelected(item);
        }
    }

}

这是我的AndroidManifest的摘录：

 <activity android:name="com.app.frisbeee.MainFragment.TabMainFragment" 
            android:theme="@style/Theme.Rosenormal" />

最后，我的style.xml文件：
