Android - ส่งค่าตัวแปรผ่าน intent แต่ไม่เปลี่ยนหน้า Activity ยังไงครับ

public class Tap extends Activity {
	private TabHost myTabHost;
	private LocalActivityManager myLocalActivityManager;

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.tap);
		myTabHost = (TabHost)findViewById(android.R.id.tabhost);
		myLocalActivityManager = new LocalActivityManager(this,false);
		myTabHost.setup(myLocalActivityManager);
		myLocalActivityManager.dispatchCreate(savedInstanceState);

		TabHost.TabSpec spec;
		
		Intent Intent= getIntent();
    	String Fac_U = Intent.getStringExtra("Fac_U");
    	String Sex_U = Intent.getStringExtra("Sex_U");
    	String Bor_U = Intent.getStringExtra("Bor_U");
    	
		Intent goSecond = new Intent().setClass(this, Second_Activity.class);
		spec = myTabHost
				.newTabSpec("tabSecond")
				.setIndicator("",getResources().getDrawable(R.drawable.imagenews))
				.setContent(goSecond);
		myTabHost.addTab(spec);
		
		
		Intent goUni = new Intent().setClass(this, University.class);
		spec = myTabHost
				.newTabSpec("tabUni")
				.setIndicator("",getResources().getDrawable(R.drawable.university))
				.setContent(goUni);
		myTabHost.addTab(spec);

		
		Intent goFac = new Intent().setClass(this, Faculty.class);
		spec = myTabHost.newTabSpec("tabFac")
				.setIndicator("",getResources().getDrawable(R.drawable.picfaculty))
				.setContent(goFac);
		goFac.putExtra("Fac_U",Fac_U);
		myTabHost.addTab(spec);
		

		Intent goSe = new Intent().setClass(this, Soldier.class);
		spec = myTabHost
				.newTabSpec("tabSe")
				.setIndicator("",getResources().getDrawable(R.drawable.solder))
				.setContent(goSe);
		goSe.putExtra("Sex_U",Sex_U);
		myTabHost.addTab(spec);

		
		Intent goBo = new Intent().setClass(this, Borrow.class);
		spec = myTabHost
				.newTabSpec("tabBo")
				.setIndicator("",getResources().getDrawable(R.drawable.kys))
				.setContent(goBo);
		goBo.putExtra("Bor_U",Bor_U);
		myTabHost.addTab(spec);

		
		Intent goFirst = new Intent().setClass(this, First_Activity.class);
		spec = myTabHost
				.newTabSpec("tabFirst")
				.setIndicator("",getResources().getDrawable(R.drawable.search))
