如何使用ListView数组调用活动

Question

Iam使用Sherlock片段制作动作栏。而且我在操作栏中有ListView，但是我将Listview称为活动..请帮助我，谢谢.. :)

在这段代码中，有一个使用数组list的listview。而且我想mylist可以调用相同的活动。

因此可以在操作栏中点赞菜单。当我们点击listview ..他可以打电话给活动谢谢..请帮助我！

        setListAdapter(adapter);

        return super.onCreateView(inflater, container, savedInstanceState);

您需要在列表视图上使用setOnItemClickListener（）

  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);
  }
});
