我正在使用 Sherlock 片段制作动作栏。我在操作栏中有 ListView，但我的 listview 可以调用活动..请帮助我谢谢.. :)

在这段代码中有一个使用数组列表的列表视图。我想 mylist 可以调用相同的活动。

所以它可以喜欢操作栏中的菜单。当我们点击列表视图时..他可以打电话给活动谢谢..请帮助我！

请更正我的代码..如何使用列表视图中的每个选项调用活动..谢谢..

编辑 setOnItemClickListener 并插入一个条件，根据单击的项目检查项目的位置以及开始和活动。

应该看起来像这样

listview.setOnItemClickListener(new OnItemClickListener() {
  @Override
  public void onItemClick(AdapterView<?> arg0,View arg1, int position, long arg3) {
      Intent n = null; 
      switch (position){
         case 0: 
           n = new Intent(getActivity(), Class0.class);
           break;
         case 1: 
           n = new Intent(getActivity(), Class1.class);
           break;
      }
      if(null!=n)
          startActivity(n);
  }
});
