Изменение текста вкладки и цвета фона при выборе

Question

Я хочу изменить цвет и текст вкладки, когда он будет выбран. Я попробовал много в обоих xml и android. Ничего не работаю. Помощник PLS. Я расширяюсь с помощью фрагмента и используя tabpageradapter heres мой код

public class BusTab extends FragmentActivity implements OnTabChangeListener { 

ViewPager Tab; 
TabPagerAdapter TabAdapter; 
ActionBar actionBar; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_bus_tab); 

    TabAdapter = new TabPagerAdapter(getSupportFragmentManager()); 

     Tab = (ViewPager)findViewById(R.id.pager); 
     Tab.setOnPageChangeListener(
       new ViewPager.SimpleOnPageChangeListener() { 
        @Override 
        public void onPageSelected(int position) { 

         actionBar = getActionBar(); 
         actionBar.setSelectedNavigationItem(position);     } 
       }); 
     Tab.setAdapter(TabAdapter); 

     actionBar = getActionBar(); 
     //Enable Tabs on Action Bar 
     actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 

     ActionBar.TabListener tabListener = new ActionBar.TabListener(){ 

      @Override 
      public void onTabReselected(android.app.ActionBar.Tab tab, 
        FragmentTransaction ft) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) { 

       Tab.setCurrentItem(tab.getPosition()); 



      } 

      @Override 
      public void onTabUnselected(android.app.ActionBar.Tab tab, 
        FragmentTransaction ft) { 
       // TODO Auto-generated method stub 

      }}; 
      //Add New Tab 

      actionBar.addTab(actionBar.newTab().setText("BUSNO").setTabListener(tabListener)); 
      actionBar.addTab(actionBar.newTab().setText("ROUTE").setTabListener(tabListener)); 

} 
@Override 
public void onTabChanged(String tabId) { 
    // TODO Auto-generated method stub 

} 

}

Использование tab_indicator для каждой вкладки, как

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="0dp" 
    android:layout_height="50dp" 
    android:layout_weight="1" 
    android:background="@color/white" 
    android:orientation="horizontal" > 

    <LinearLayout 
     android:layout_width="0dp" 
     android:layout_height="match_parent" 
     android:layout_weight="1" 
     android:orientation="vertical" > 

     <TextView 
      android:id="@+id/tv_tab_txt" 
      style="?android:attr/tabWidgetStyle" 
      android:layout_width="match_parent" 
      android:layout_height="0dp" 
      android:layout_weight="1" 
      android:gravity="center" 
      android:paddingBottom="10dp" 
      android:paddingTop="10dp" 
      android:text="@string/live" 
      android:textColor="@drawable/tab_text_color" 
      android:textStyle="bold" /> 

     <View 
      android:layout_width="match_parent" 
      android:layout_height="4dp" 
      android:layout_gravity="bottom" 
      android:background="@drawable/tab_underline_selector" /> 
    </LinearLayout> 

    <View 
     android:layout_width="1dp" 
     android:id="@+id/tabs_divider_view" 
     android:layout_height="30dp" 
     android:layout_marginBottom="10dp" 
     android:layout_marginTop="10dp" 
     android:background="@color/grey_background" /> 

</LinearLayout> 

и растяжимой tab_text_color как

<?xml version="1.0" encoding="utf-8"?> 

<item android:state_selected="true" android:color="@color/dark_blue"/> 
<item android:state_pressed="true" android:color="@color/dark_blue"/> 
<item android:color="@color/dark_gray" /> 

и tab_underline_selector, как

<?xml version="1.0" encoding="utf-8"?> 

<item android:drawable="@color/dark_blue" android:state_selected="true"/> 
<item android:drawable="@color/transparent"/> 

и в вашем фрагменте

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

    View view = inflater.inflate(R.layout.entries_tabs, container, false); 
    HorseRacesNowMainActivity.setHeaders(this); 

    mTabHost = (FragmentTabHost) view.findViewById(android.R.id.tabhost); 

    mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent); 

    View tabIndicatorToday = LayoutInflater.from(getActivity()).inflate(R.layout.tab_indicator, mTabHost.getTabWidget(), false); 
    ((TextView) tabIndicatorToday.findViewById(R.id.tv_tab_txt)).setText(getResources().getString(R.string.today)); 

    mTabHost.addTab(mTabHost.newTabSpec(getResources().getString(R.string.today)).setIndicator(tabIndicatorToday), EntriesTodayFragment.class, null); 

    View tabIndicatorLive = LayoutInflater.from(getActivity()).inflate(R.layout.tab_indicator, mTabHost.getTabWidget(), false); 
    ((TextView) tabIndicatorLive.findViewById(R.id.tv_tab_txt)).setText(getResources().getString(R.string.live)); 

    mTabHost.addTab(mTabHost.newTabSpec(getResources().getString(R.string.live)).setIndicator(tabIndicatorLive), EntriesLiveFragment.class, null); 

    View tabIndicatorTrack = LayoutInflater.from(getActivity()).inflate(R.layout.tab_indicator, mTabHost.getTabWidget(), false); 
    ((TextView) tabIndicatorTrack.findViewById(R.id.tv_tab_txt)).setText(getResources().getString(R.string.by_track)); 
    tabIndicatorTrack.findViewById(R.id.tabs_divider_view).setVisibility(View.INVISIBLE); 

    mTabHost.addTab(mTabHost.newTabSpec(getResources().getString(R.string.by_track)).setIndicator(tabIndicatorTrack), EntriesTrackFragment.class, null); 

    return view; 
}
