步骤1)编写点击界面

创建一个名为RecyclerViewClickListener.java的接口，并添加以下代码。这里我们声明了两个方法onClick和onLongClick，分别用于标识项目单击和长单击。

package com.androidtutorialshub.recyclerviewtutorial.Helper;

import android.view.View;

public interface RecyclerViewClickListener {
    void onClick(View view, int position);

    void onLongClick(View view, int position);
}

步骤2)编写项目触摸类

创建一个名为RecyclerViewTouchListener.java的类，并添加以下代码。这里我们编写了检测点击和长按回收器视图项的逻辑。

package com.androidtutorialshub.recyclerviewtutorial.Helper;

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;


public class RecyclerViewTouchListener implements RecyclerView.OnItemTouchListener{

    private GestureDetector gestureDetector;
    private RecyclerViewClickListener clickListener;

    public RecyclerViewTouchListener(Context context, final RecyclerView recyclerView, final RecyclerViewClickListener clickListener) {
        this.clickListener = clickListener;
        gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }

            @Override
            public void onLongPress(MotionEvent e) {
                View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
                if (child != null && clickListener != null) {
                    clickListener.onLongClick(child, recyclerView.getChildPosition(child));
                }
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {

        View child = rv.findChildViewUnder(e.getX(), e.getY());
        if (child != null && clickListener != null && gestureDetector.onTouchEvent(e)) {
            clickListener.onClick(child, rv.getChildPosition(child));
        }
        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView rv, MotionEvent e) {
    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
}

步骤3)定义点击监听器

打开MainActivity.java并更新以下更改。这里onClick()方法将检测点击项目，onLongClick将检测长时间点击项目。

recyclerView.addOnItemTouchListener(new RecyclerViewTouchListener(getApplicationContext(), recyclerView, new RecyclerViewClickListener() {
            @Override
            public void onClick(View view, int position) {
                Toast.makeText(getApplicationContext(), bookList.get(position).getTitle() + " is clicked!", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onLongClick(View view, int position) {
                Toast.makeText(getApplicationContext(), bookList.get(position).getTitle() + " is long pressed!", Toast.LENGTH_SHORT).show();

            }
        }));

欲了解更多信息或下载源代码:http://www.androidtutorialshub.com/android-recyclerview-click-listener-tutorial/

这对我来说很管用。将OnClickListener附加到onBindView。我真的不知道这是否会影响性能，但它似乎用很少的代码就能很好地工作。

public void onBindViewHolder(ViewHolder holder, final int position) {
    holder.view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(context, "Recycle Click" + position, Toast.LENGTH_SHORT).show();
            }
    });
}

From most of the answers above, they seem to be setting their onclicklisteners to individual items. However, the solution am about to offer is very simple but yet not intuitive to many. Many are forgetting that the other components are always in a parent component which is used to display items in the List or Recycler views. This solution is just about setting a single onclick listener to this parent view and the turn is played. The solution also includes a way to pass the position of the item being clicked on from the list or recycler view. Here, our main rootview is a CardView from the android support library. Here is sample code

public class ListAdapter extends RecyclerView.Adapter<ListAdapter.ViewHolder> {

public static final String LOG_TAG = ListAdapter.class.getSimpleName();
private Cursor mDataset;
private Context mContext;
private ViewHolder mViewHolder;

// Provide a suitable constructor (depends on the kind of dataset)
public ListAdapter(Context context, Cursor Dataset) {
    mDataset = Dataset;
    mContext = context;
}

// Create new views (invoked by the layout manager)
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    // create a new view
    View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.list_business_view, parent, false);

    mViewHolder = new ViewHolder(v);
    return mViewHolder;
}

public void setData(Cursor newdata) {
    this.mDataset = newdata;
}

// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
//Bind data to other items here. To save time, i have ommited that.
           //here is where we attach a click listerner for an item in the recycler list rather than for each element of a given item.
            holder.card.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(mContext, " Just cliked item at position " + itemPosition, Toast.LENGTH_LONG).show();

            }
        });

    }
}

// Return the size of your dataset (invoked by the layout manager)
@Override
public int getItemCount() {
    if (null != mDataset) {
        return mDataset.getCount();
    }
    return 0;

}


// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public static class ViewHolder extends RecyclerView.ViewHolder{
    // each data item is just a string in this case
    public final TextView mBusinesssName; // View for the business name
    public final TextView mBusinessCategory; //View for the category name
    public final ImageView businessImage; // View for the business category image Image
    public final TextView mBusinessDistance; // View for the distance
    public final CardView card;

    public ViewHolder(View view) {
        super(view);
        mBusinesssName = (TextView) view.findViewById(R.id.list_item_name_textview);
        mBusinessCategory = (TextView) view.findViewById(R.id.list_item_category_textview);
        mBusinessDistance = (TextView) view.findViewById(R.id.list_item_dist_textview);
        businessImage = (ImageView) view.findViewById(R.id.list_item_icon);
        card = (CardView) view.findViewById(R.id.card_view);

    }
}
}

我有一个很好的解决方案RecyclerView的onItemClickListener的项目和子项

步骤1—创建接口

public interface OnRecyclerViewItemClickListener
{
    /**
     * Called when any item with in recyclerview or any item with in item
     * clicked
     * 
     * @param position
     *            The position of the item
     * @param id
     *            The id of the view which is clicked with in the item or
     *            -1 if the item itself clicked
     */
    public void onRecyclerViewItemClicked(int position, int id);
}

步骤2-然后在适配器的onBindViewHolder方法中使用它，如下所示

/**
     * Custom created method for Setting the item click listener for the items and items with in items
     * @param listener OnRecyclerViewItemClickListener 
     */
    public void setOnItemClickListener(OnRecyclerViewItemClickListener listener)
    {
        this.listener = listener;
    }

    @Override
    public void onBindViewHolder(ViewHolder viewHolder, final int position)
    {
    
        // viewHolder.albumBg.setBackgroundResource(_itemData[position]
        // .getImageUrl());
    
        viewHolder.albumName.setText(arrayList.get(position).getName());
        viewHolder.artistName.setText(arrayList.get(position).getArtistName());
        String imgUrl = arrayList.get(position).getThumbImageUrl();
    
        makeImageRequest(imgUrl, viewHolder);
        viewHolder.parentView.setOnClickListener(new View.OnClickListener()
        {
    
            @Override
            public void onClick(View v)
            {
                listener.onRecyclerViewItemClicked(position, -1);
            }
        });
        viewHolder.settingButton.setOnClickListener(new View.OnClickListener()
        {
    
            @Override
            public void onClick(View v)
            {
                listener.onRecyclerViewItemClicked(position, v.getId());
            }
        });
    
    }
    
    // class to hold a reference to each item of RecyclerView
    public static class ViewHolder extends RecyclerView.ViewHolder
    {
    
        public TextView albumName, artistName;
        public ImageView albumIcon, settingButton;
        public LinearLayout parentView;
    
        public ViewHolder(View itemLayoutView)
        {
            super(itemLayoutView);
            // albumBg = (LinearLayout) itemLayoutView
            // .findViewById(R.id.albumDlbg);
            albumName = (TextView) itemLayoutView.findViewById(R.id.albumName);
            artistName = (TextView) itemLayoutView
                    .findViewById(R.id.artistName);
            albumIcon = (ImageView) itemLayoutView.findViewById(R.id.albumIcon);
            parentView = (LinearLayout) itemLayoutView
                    .findViewById(R.id.albumDlbg);
            settingButton = (ImageView) itemLayoutView
                    .findViewById(R.id.settingBtn);
        }
    
    }

步骤3-在活动或片段中找到并设置回收器视图，您正在使用此

recyclerView = (RecyclerView) rootview.findViewById(R.id.vmtopsongs);

        lm = new LinearLayoutManager(mActivity);
        lm.setOrientation(LinearLayoutManager.VERTICAL);
        recyclerView.setLayoutManager(lm);
        recyclerView.addItemDecoration(
                new HorizontalDividerItemDecoration.Builder(getActivity())
                        .paint(Utils.getPaint()).build());
        PopularSongsadapter mAdapter = new PopularSongsadapter(gallery,
                mActivity, true);
        // set adapter
        recyclerView.setAdapter(mAdapter);
        mAdapter.setOnItemClickListener(this);
        // set item animator to DefaultAnimator
        recyclerView.setItemAnimator(new DefaultItemAnimator());

步骤4-最后在使用recyclerview的activity或fragment中实现接口

@Override
    public void onRecyclerViewItemClicked(int position, int id)
    {
        if(id==-1){
            Toast.makeText(mActivity, "complete item clicked", Toast.LENGTH_LONG).show();
        }else{
            Toast.makeText(mActivity, "setting button clicked", Toast.LENGTH_LONG).show();
        }
    }

更新Kotlin语言 我已经更新了kotlin的代码，其中只有整个视图有点击监听器。你可以根据上面的java代码编辑界面和代码来设置子项点击监听器。

适配器

class RecentPostsAdapter(private val list: MutableList<Post>) :
    RecyclerView.Adapter<RecentPostsAdapter.ViewHolder>() {
    private lateinit var onItemClickListener: OnItemClickListener

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
        return ViewHolder(
            LayoutInflater.from(parent.context)
                .inflate(R.layout.listitem_recent_post, parent, false)
        )
    }

    override fun getItemCount(): Int {
        return list.size
    }

    fun setOnItemClickListener(onItemClickListener: OnItemClickListener) {
        this.onItemClickListener = onItemClickListener
    }

    private fun getItem(position: Int): Post {
        return list[position]
    }

    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        holder.bind(getItem(position))
        holder.itemView.setOnClickListener(View.OnClickListener {
            onItemClickListener.onItemClick(
                position
            )
        })
    }

    class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        private var imageView: NetworkImageView? = null
        private var tvTitle: TextView? = null
        private var tvExcerpt: TextView? = null
        private var htmlSpanner: HtmlSpanner = HtmlSpanner()

        init {
            imageView = itemView.findViewById(R.id.niv_post_image)
            tvTitle = itemView.findViewById(R.id.tv_post_title)
            tvExcerpt = itemView.findViewById(R.id.tv_post_excerpt)
        }

        fun bind(post: Post) {
            tvTitle?.text = post.title
            tvExcerpt?.text = htmlSpanner.fromHtml(post.excerpt)
        }
    }

    interface OnItemClickListener {
        fun onItemClick(position: Int)
    }
}

活动或片段

recyclerView = view.findViewById(R.id.rvHomeRecentPosts)
        recyclerView.layoutManager = LinearLayoutManager(view.context)
        list = mutableListOf()
        recentPostsAdapter = RecentPostsAdapter(list)
        recyclerView.adapter = recentPostsAdapter
        recentPostsAdapter.setOnItemClickListener(object:RecentPostsAdapter.OnItemClickListener{
            override fun onItemClick(position: Int) {
                (activity as MainActivity).findNavController(R.id.nav_host_fragment).navigate(R.id.action_nav_home_to_nav_post_detail)
            }

        })

你可以实现View。OnClickListener到你的ViewHolder类

public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        
    public Item item
    @InjectView(R.id.tv_title) 
    public TextView tvTitle;
    @InjectView(R.id.rl_row) 
    public RelativeLayout rlRow;

    public ViewHolder(View v) {
        super(v);
        ButterKnife.inject(this, v);
        v.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        Log.e("item title",item.getTitle());
    }
}

和onBindViewHolder设置你的视图持有人的项目:

public void onBindViewHolder(ViewHolder holder, int position) {
    holder.tvTitle.setText(objects.get(position).getTitle());
    holder.item = objects.get(position);
}

在kotlin中使用构造函数实现

初始化你的RecyclerView构造函数，如下所示:

class ListAdapter(
    c: Context,
    private var list: List<Project>,
    private val itemClick: (Project) -> Unit
) : RecyclerView.Adapter<ListAdapter.ViewHolder>() 

在onCreateViewHolder中使用itemClick返回:

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int):ProjectViewHolder {
    val view = inflater.inflate(R.layout.list_item, parent, false)
    return ViewHolder(view, itemClick)
}

你的onBindViewHolder:

override fun onBindViewHolder(holder: ViewHolder, position: Int) {
    holder.bindProject(list[position])
}

然后用ViewHolder类创建bindProject函数。

class ViewHolder(
    view: View,
    private val itemClick: (Project) -> Unit
) : RecyclerView.ViewHolder(view) {

    private val clientTextCount = 7

    val titleTextView: TextView = view.projectTitleTextView
 
    fun bindProject(project: Project) {
        with(project) {
            titleTextView.text = name
            itemView.setOnClickListener { itemClick(this) }
        }
    }
}

最后在您的活动中用lazy初始化适配器

private val adapter: ListAdapter by lazy {
    ListAdapter(this, projectList, {
        // Here you can implement your onClick function.
    })
}

在适配器中为RecyclerView添加新列表初始化以下方法:

fun setProjects(projects: List<Project>) {
    projectList = projects
    notifyDataSetChanged()
}

在你的活动中调用setProjects方法:

adapter.setProjects(projects)

就是这样。
