TabHost控件使用Intent创建子页面，TabActivity如何获取页面的内容

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);



        final TabHost tabHost = getTabHost();



        //这里用的是new Intent(this, List1.class)

        //我怎么获取到List1、List2 输入的内容？？？

        tabHost.addTab(tabHost.newTabSpec("tab1")

                .setIndicator("list")

                .setContent(new Intent(this, List1.class)));



        tabHost.addTab(tabHost.newTabSpec("tab2")

                .setIndicator("photo list")

                .setContent(new Intent(this, List8.class)));

    }
