Android Studio：关于ListView点击事件该怎么写？

Question

我定义了一个名为RecommendItem的类，里面包含一系统数据和一个Intent，并且定义了getIntent()方法，我想通过该方法获取要跳转的界面，从而实现点击ListView的item实现相应的跳转。
利用自定义的适配器实现了以下界面

之后我想添加item的点击事件，应该怎么写才对呢？

//写在fragment的onActivityCreated()方法内，所以加了getActivity()
ListView recommend_viewlist = getActivity().findViewById(R.id.recommend_list);
//自定义的适配器，运行后展示正常，显示内容是一个含有很多RecommendItem对象应该List
List<RecommendItem> recommend_list = new ArrayList<RecommendItem>();// 定义要加入数据的list
// 创建加入表中的RecommendItem对象
RecommendItem diet1 = new RecommendItem(R.drawable.diet1,"轻断食第1天","#饮食","","");
Intent d1 = new Intent(getContext(), Diet1Activity.class);
diet1.setIntent(d1);
RecommendItemdiet2 = new RecommendItem(R.drawable.diet2,"轻断食第2天","#饮食","","");
Intent d2 = new Intent(getContext(), Diet2Activity.class);
diet2.setIntent(d2);
RecommendItemdiet3 = new RecommendItem(R.drawable.diet3,"轻断食第3天","#饮食","","");
Intent d3 = new Intent(getContext(), Diet3Activity.class);
diet3.setIntent(d3);
// 上述RecommendItem对象有很多，加入表里的顺序也不确定(打算弄推荐算法)，所有不能用switch(position)方法写事件响应
recommend_list.add(diet1);//这样写的加入表里的代码

MyListAdapter adapter = new MyListAdapter();
recommend_viewlist.setAdapter(adapter);
recommend_viewlist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
      @Override
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
             // 这里应该怎么写？看不懂上面参数代表什么
             // 我想获取点击的这一项的RecommendItem对象，然后通过其getIntent()方法获取intent，然后实现页面跳转
      }
});

// 自定义适配器
class MyListAdapter extends BaseAdapter {
        @Override
        public int getCount() {            return recommend_list.size();        }
        @Override
        public Object getItem(int position) {           return recommend_list.get(position);        }
        @Override
        public long getItemId(int position) {           return position;        }
        @Override
        public View getView(int position, View convertView, ViewGroup parent) { 
            MyViewHolder holder;
            if(convertView == null) {
                convertView = View.inflate(getContext(),R.layout.community_list_item,null);//布局就是上面显示的图片
                holder = new MyViewHolder();
                holder.recommend_title = convertView.findViewById(R.id.recommended_title);
                holder.recommend_tag = convertView.findViewById(R.id.recommended_tags);
                holder.recommend_cover = convertView.findViewById(R.id.recommended_cover);
                convertView.setTag(holder);
            }
            else
                holder = (MyViewHolder)convertView.getTag();
            RecommendItem obj = recommend_list.get(position);
            holder.recommend_title.setText(obj.getItemTitle());
            holder.recommend_cover.setImageResource(obj.getItemId());
            holder.recommend_tag.setText(obj.getTag());
            return convertView;
        }
        class MyViewHolder {// 每个item布局含有一个图片，两个TextView
            TextView recommend_title,recommend_tag;
            ImageView recommend_cover;
        }
    }

RecommendItem类：

public class RecommendItem {
    public int itemId; // 推荐元素封面id，例：R.drawable.xx
    public String itemTitle; // 推荐元素标题
    public String tag1; // 推荐元素标签
    public String tag2;
    public String tag3;
    public String tag;
    public Intent intent;

    public RecommendItem() {    }
    public RecommendItem(int itemId, String itemTitle, String tag1, String tag2, String tag3) {
        this.itemId = itemId;
        this.itemTitle = itemTitle;
        this.tag1 = tag1;
        this.tag2 = tag2;
        this.tag3 = tag3;
        this.tag = tag1+" "+tag2+" "+tag3;
    }
    public String getTag() {      return tag1+" "+tag2+" "+tag3;   }
    // 设置了set和get Intent 的方法
    public Intent getIntent() {       return intent;   }
    public void setIntent(Intent intent) {       this.intent = intent;    }
}
