public class TabUiActivity extends TabActivity implements OnTabChangeListener{
	
	private TabHost tabHost;
	
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        tabHost = getTabHost();
        tabHost.setOnTabChangedListener(this);
        
        
        tabHost.addTab(tabHost.newTabSpec("Memo")
                .setIndicator(getResources().getString(R.string.fir)
                        ,getResources().getDrawable(R.drawable.ic_tab_memo))
                .setContent(new Intent(this, FirActivity.class)));
        
        tabHost.addTab(tabHost.newTabSpec("Appointment")
                .setIndicator(getResources().getString(R.string.sec)
                        ,getResources().getDrawable(R.drawable.ic_tab_appointment))
                .setContent(new Intent(this, SecActivity.class)));
    }

	@Override
	public void onTabChanged(String tabId) {
		System.out.println("=========" + tabId);
