Android: How to Remove Selected Tab Highlight Color & On Press Highlight on TabWidget

I am now working with Android TabWidget.
I build this TabWidget based on http://mobileorchard.com/android-app-development-tabbed-activities/

I've already add background to the TabWidget,

but apparently the highlight of selected tab and pressed tab is always visible and I cant turn it off yet.

Here is the picture (sorry cant directly add image because still a newb). :

1. default selected tab : http://postimage.org/image/9ryed6w5b/

2. on pressed tab : http://postimage.org/image/gwg7m83en/

What I want is the default selected tab color and on pressed tab color to be invisible or turned off, so the image background will fully shown, not blocked by those colors.

Any response will be appreciated. Thank you :)

the code:

public void onCreate(Bundle savedInstanceState) {
         //hide title bar
         BasicDisplaySettings.toggleTaskBar(EpolicyMainActivity.this, false);
         //show status bar
         BasicDisplaySettings.toggleStatusBar(EpolicyMainActivity.this, true);
 
         super.onCreate(savedInstanceState);
         setContentView(R.layout.epolicy);
         TabHost tabHost=(TabHost)findViewById(R.id.tabHost);
         tabHost.setup();
         tabHost.getTabWidget().setBackgroundColor(0);
         tabHost.getTabWidget().setBackgroundResource(R.drawable.epolicy_menu_bar);      
 
         TabSpec spec1=tabHost.newTabSpec("Tab 1");
         spec1.setContent(R.id.tab1);
         spec1.setIndicator("",getResources().getDrawable(R.drawable.epolicy_menu_home));
 
         TabSpec spec2=tabHost.newTabSpec("Tab 2");
         spec2.setContent(R.id.tab2);
         spec2.setIndicator("",getResources().getDrawable(R.drawable.epolicy_menu_nab));
 
         TabSpec spec3=tabHost.newTabSpec("Tab 3");
         spec3.setContent(R.id.tab3);
         spec3.setIndicator("",getResources().getDrawable(R.drawable.epolicy_menu_contact));
 
         TabSpec spec4=tabHost.newTabSpec("Tab 4");
         spec4.setContent(R.id.tab4);
         spec4.setIndicator("",getResources().getDrawable(R.drawable.epolicy_menu_agen));
