Hi Friends i resolved my issue by passing value through intent to main tab activity, here below is sample code,Set this code lines to child activity of tab that means if i relate to above question child activity is "B1",

Intent homeIntent = new Intent(SelectFetchee.this, Home.class);
            homeIntent.putExtra("tabvalue", "2");
            startActivity(homeIntent);
Then in main activity that have tabhost in which i collect the string

String crntTab = getIntent().getStringExtra("tabvalue");

        if (crntTab == null) {
            tabHost.setCurrentTab(2);
        } else if (crntTab.toString().equals("4")) {

            tabHost.setCurrentTab(4);
        } else if (crntTab.toString().equals("2")) {
            tabHost.setCurrentTab(2);
        } else if (crntTab.toString().equals("3")) {
            tabHost.setCurrentTab(3);
        } else if (crntTab.toString().equals("0")) {
            tabHost.setCurrentTab(0);
        } else if (crntTab.toString().equals("1")) {
            tabHost.setCurrentTab(1);
        }
