        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));
