最近在项目开发过程当中使用到了列表的点击事件，由于列表用的是RecyclerView控件进行开发的，所以就涉及到了RecylerView的点击事件。具体的思路是在RecyclerView的Adapter当中定义响应点击事件的接口，然后再recycerView.set(adapter)的时候能够直接处理点击事件。这里我直接粘贴出我项目代码中的文件供大家参考：
SameContentListRecyclerViewAdapter .java
package com.yqzbw.yqms.lb.adapter;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import com.yqzbw.yqms.lb.activity.R;
import com.yqzbw.yqms.lb.util.OtherUtil;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import java.util.Locale;
import java.util.Map;
/**

* Description: 该类是列表展示Adapter
*/
public class SameContentListRecyclerViewAdapter extends RecyclerView.Adapter implements View.OnClickListener {
private List> dataList;
private OnItemClickListener mOnItemClickListener = null;
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_same_content_list, parent, false);
view.setOnClickListener(this);
return new ViewHolder(view);
}
public SameContentListRecyclerViewAdapter(List> dataList) {
this.dataList = dataList;
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
//标题需要进行一下过滤，因为标题文件当中可能含有html的标签
holder.titleTextView.setText(OtherUtil.filter(dataList.get(position).get("kvTitle")));
holder.sourceTextView.setText(dataList.get(position).get("kvSite"));
//在这里要对时间做一下处理
String showTime = "";
String dateTime = dataList.get(position).get("kvCtime");
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddHHmmSS", Locale.getDefault());
try {
Date parse = dateFormat.parse(dateTime);
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:SS", Locale.getDefault());
showTime = format.format(parse);
} catch (ParseException e) {
e.printStackTrace();
}
holder.timeTextView.setText(showTime);
//设置来源图片
String kvSourcetype = dataList.get(position).get("kvSourcetype");
int imageId = getImageIdBySourceType(kvSourcetype);
holder.sourceImage.setBackgroundResource(imageId);
//将position保存在itemView的Tag中，以便点击时进行获取
holder.itemView.setTag(position);
}
/**
* 根据类型得到对应的图片id
* @param kvSourcetype
* @return
*/
private int getImageIdBySourceType(String kvSourcetype) {
//默认为微博图片
int imageId = R.drawable.weibo04;
switch (kvSourcetype) {
case "01":
imageId = R.drawable.news01;
break;
case "02":
imageId = R.drawable.forum02;
break;
case "03":
imageId = R.drawable.blog03;
break;
case "04":
imageId = R.drawable.weibo04;
break;
case "05":
imageId = R.drawable.media05;
break;
case "06":
imageId = R.drawable.weixin;
break;
case "07":
imageId = R.drawable.video07;
break;
case "08":
imageId = R.drawable.longweibo08;
break;
case "09":
imageId = R.drawable.app09;
break;
case "10":
imageId = R.drawable.comment10;
break;
case "99":
imageId = R.drawable.other99;
break;
case "1":
imageId = R.drawable.news01;
break;
case "2":
imageId = R.drawable.forum02;
break;
case "3":
imageId = R.drawable.blog03;

break;
case "8":
imageId = R.drawable.longweibo08;
break;
case "9":
imageId = R.drawable.app09;
break;
default:
break;
}
return imageId;
}
@Override
public int getItemCount() {
return dataList.size();
}
/**
* 响应点击事件
* @param v
*/
@Override
public void onClick(View v) {
if (mOnItemClickListener != null) {
//注意这里使用getTag方法获取position
mOnItemClickListener.onItemClick(v, (int)v.getTag());
}
}
/**
* 设置listener事件并初始化
* @param listener
*/
public void setOnItemClickListener(OnItemClickListener listener) {
this.mOnItemClickListener = listener;
}
static class ViewHolder extends RecyclerView.ViewHolder {
TextView titleTextView;
ImageView sourceImage;
TextView sourceTextView;
TextView timeTextView;
public ViewHolder(View itemView) {
super(itemView);
titleTextView = (TextView)itemView.findViewById(R.id.tv_title);
sourceTextView = (TextView)itemView.findViewById(R.id.tv_source);
timeTextView = (TextView)itemView.findViewById(R.id.tv_time);
sourceImage = (ImageView)itemView.findViewById(R.id.iv_source);
}
}
/**
* 定义点击事件的接口
*/
public interface OnItemClickListener {
void onItemClick(View view , int position);
}
}
使用adapter
//设置adapter，填充列表信息
SameContentListRecyclerViewAdapter sameContentListRecyclerViewAdapter = new SameContentListRecyclerViewAdapter(dataList);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity());
linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
sameContentRecyclerView.setLayoutManager(linearLayoutManager);
sameContentRecyclerView.setAdapter(sameContentListRecyclerViewAdapter);
//为Adapter添加点击事件
sameContentListRecyclerViewAdapter.setOnItemClickListener(new SameContentListRecyclerViewAdapter.OnItemClickListener() {
@Override
public void onItemClick(View view, int position) {
Toast.makeText(getActivity(), "position = " + position, Toast.LENGTH_SHORT).show();
//在这里获取到position之后就可以做你想要的操作，当然你可以根据自己的需要传递不同的参数
}
});
