Android RecycleView(三)——增加点击事件

上一篇Android RecycleView(二) 给recycleview添加了分割线，这篇来给他添加点击事件。

其实在adapter中添加一个回掉即可。

package com.chs.myrecycleview.adapter;import android.content.Context;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.LinearLayout;import android.widget.TextView;import com.chs.myrecycleview.R;import java.util.List;/** * 作者：chs on 2016/2/2 14:43 * 邮箱：657083984@qq.com */public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {    private Context mContext;    private List<String> mData;    private OnItemClickListener onItemClickListener;    public void setOnItemClickListener(OnItemClickListener onItemClickListener) {        this.onItemClickListener = onItemClickListener;    }    public interface OnItemClickListener{        void onItemClick(View view, int position);    }    public MyAdapter(Context mContext,List<String> list) {        this.mContext = mContext;        this.mData = list;    }    @Override    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = LayoutInflater.from(mContext).inflate(R.layout.item,parent,false);        MyViewHolder holder = new MyViewHolder(view);        return holder;    }    @Override    public void onBindViewHolder(final MyViewHolder holder, final int position) {        holder.tv_text.setText(mData.get(position));        if(onItemClickListener!=null){           holder.ll_main.setOnClickListener(new View.OnClickListener() {               @Override               public void onClick(View v) {                   onItemClickListener.onItemClick(holder.itemView,position);               }           });        }    }    @Override    public int getItemCount() {        return mData.size();    }    class MyViewHolder extends RecyclerView.ViewHolder{        TextView tv_text;        LinearLayout ll_main;        public MyViewHolder(View itemView) {            super(itemView);            tv_text = (TextView) itemView.findViewById(R.id.tv_text);            ll_main = (LinearLayout) itemView.findViewById(R.id.ll_main);        }    }}

MainActivity中：

 myAdapter.setOnItemClickListener(new MyAdapter.OnItemClickListener() {            @Override            public void onItemClick(View view, int position) {                Toast.makeText(MainActivity.this,"点击了"+position,Toast.LENGTH_SHORT).show();            }        });

就这么简单，设置长按监听和这个原理一样

效果：
