Android 中RecycleView實(shí)現(xiàn)item的點(diǎn)擊事件

RecycleView現(xiàn)在已經(jīng)越來(lái)越受到大家的重視，因?yàn)樗瓤梢源鎙istView還可以代替GridView，但是RecycleView本身不不像ListView那樣具有setOnItemClickListener,這個(gè)關(guān)于子item的點(diǎn)擊，但是我們往往會(huì)用到RecycleView并且希望他的自孩子可以被點(diǎn)擊，那么如何實(shí)現(xiàn)他的item的點(diǎn)擊事件呢？

首先我們?cè)赗ecyclerView.ViewHolder中的實(shí)現(xiàn)：

public class GridViewHolder extends RecyclerView.ViewHolder implements OnClickListener{
  
  //聲明MyItemClickListener
  private MyItemClickListener mListener; 
  public GridViewHolder(View rootView,MyItemClickListener listener) {
    super(rootView);
    this.mListener = listener; 
    rootView.setOnClickListener(this);
    
  }
  @Override
  public void onClick(View v) {
//如果mListener不為空，就實(shí)現(xiàn)接口中的方法onItemClick其中g(shù)etPosition()是得到被點(diǎn)擊位置的position
     if(mListener != null){ 
        mListener.onItemClick(v,getPosition()); 
      } 
  }
   
//聲明MyItemClickListener這個(gè)接口
    public interface MyItemClickListener { 
    public void onItemClick(View view,int postion); 
  } 
}

最后在RecyclerViewAdapter中實(shí)現(xiàn)：

package com.ledon.activity.adapter;

import Java.util.ArrayList;
import java.util.List;

import com.ledon.activity.adapter.GridViewHolder.MyItemClickListener;
import com.ledon.ledongym.R;
import com.lidroid.xutils.BitmapUtils;

import Android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.text.TextUtils;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;

public class RecyclerViewAdapter extends RecyclerView.Adapter<GridViewHolder> {
  private final List<String> labels;
  private LayoutInflater mLayoutInflater;
  private Context context;
  private MyItemClickListener mItemClickListener;

  
  public RecyclerViewAdapter(int count, Context context) {
    this.labels = new ArrayList<String>(count);
    mLayoutInflater = LayoutInflater.from(context);
    for (int i = 0; i < count; i++) {
      labels.add(String.valueOf(i));
    }
  }

  @Override
  public int getItemCount() {
    return labels.size();
  }

  

  @Override
  public void onBindViewHolder(GridViewHolder viewHolder, int position) {
    viewHolder.itemView.setTag(labels.get(position));
   

  }

  @Override
  public GridViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    
    View view = null;
   
    view = mLayoutInflater.inflate(R.layout.item_userinfo, parent, false);
   //通過(guò)構(gòu)造函數(shù)將mItemClickListener
    GridViewHolder holder = new GridViewHolder(view, mItemClickListener);
    return holder;
  }

  /**
   * 設(shè)置Item點(diǎn)擊監(jiān)聽(tīng)
   * 
   * @param listener
   */
  public void setOnItemClickListener(MyItemClickListener listener) {
    this.mItemClickListener = listener;
  }

  
  
}

最后在activity中

//根據(jù)adapter來(lái)設(shè)置item的點(diǎn)擊事件
    recyclerViewAdapter.setOnItemClickListener(new MyItemClickListener() {
      
      @Override
      public void onItemClick(View view, int postion) {
        
      }
    });
