        intent1 = new Intent(TestActivity.this, one.class);
        tabhost.addTab(tabhost.newTabSpec("one")
        		.setIndicator("电话", getResources().getDrawable(android.R.drawable.ic_menu_call))
        		.setContent(intent1));
    
        intent2 = new Intent(TestActivity.this,one.class);
        tabhost.addTab(tabhost.newTabSpec("two")
        		.setIndicator("相机", getResources().getDrawable(android.R.drawable.ic_menu_camera))
        		.setContent(intent2));
    
    
    }

如果包含的 activity 里面有 intent 就会跳出 tab

tabhost.setCurrentTab(1); 跳转到 指定 ID 的 TAB ,  从0 开始
