    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        th=Control_TabHostActivity.this.getTabHost();
        LayoutInflater lif=getLayoutInflater();
        lif.inflate(R.layout.main, th.getTabContentView(),true);
        th.addTab(th.newTabSpec("view1").setIndicator("a").setContent(R.id.view1));
        th.addTab(th.newTabSpec("view2").setIndicator("b").setContent(R.id.view2));
        th.addTab(th.newTabSpec("view3").setIndicator("c").setContent(R.id.view3));
        setContentView(th);
