'Unselect' a tab in a TabHost

I have a TabHost holding 5 tabs. As far as I can see, there has to be one tab selected at all times.

I need a way to unselect all my tabs so none will be selected.

If the tabhost is meant by general to have one tab selected at all times, how can I make it appear (UI speaking) as if the tab isn't selected?

This is not possible AFAIK. but yes,you can set the selected tab's color to look like it is unselected and set a blank layout over it by managing a global variable when you make it 'unselected' and setting up normal layout when you want it to be shown normally to user. But this is kind of a trick.

Hope,you get my point!

EDIT :

Suppose you have set String what="disappear" somewhere in your code to show it 'unselected',then you can use this function to change color of tab:

Main.class:

//Change The Backgournd Color of Tabs
    public void setTabColor(TabHost tabhost) {


        for(int i=0;i<tabhost.getTabWidget().getChildCount();i++)
        {
                tabhost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#FFFFFF"))); //unselected white colored                   
        }

            if(!what.equals("disappear"))
                 tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.parseColor("FF0000"))); // selected red colored

            else
                 tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.parseColor("FFFFFF"))); // selected but show as unselected with white color


    }

And in your activity class(which is opened by that selected tab):

FirstActivity.class:

if(what.equals("disappear"))
      setContentView(R.layout.blank);
else
      setContentView(R.layout.first_layout);

blank.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical"
  android:id="@+id/layout"
  android:background="#ffffff"  
  android:gravity="center">
  <!-- You can make background transperent by setting it to "00ffffff" -->
  <!-- You can also add this textview to guide user -->
  <!--
      <TextView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Click Any Tab To Start
         />
  -->
</LinearLayout>

try this:

final TabWidget tabWidget = tabHost.getTabWidget();
final int n = tabWidget.getChildCount();
for (int i = 0; i < n; ++i) {
    tabWidget.getChildAt(i).setSelected(false);
}

or you can add hidden tab and select it when you want unselect a tab

tabHost.addTab(
            tabHost.newTabSpec("hiddenTab").setIndicator(""),
            MyFragment.class,
            null
    );

tabHost.getTabWidget().getChildTabViewAt(hiddenTabIndex).setVisibility(View.GONE);

and select this tab when you want

tabHost.setCurrentTab(hiddenTabIndex);

For this purpose, maybe using tabHost is not the proper way ?
