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)
            }

        })

基于Jacob Tabak的回答(+1)，我能够添加onLongClick监听器:

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

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
    public interface OnItemClickListener {
        void onItemClick(View view, int position);

        void onItemLongClick(View view, int position);
    }

    private OnItemClickListener mListener;

    private GestureDetector mGestureDetector;

    public RecyclerItemClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) {
        mListener = listener;

        mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }

            @Override
            public void onLongPress(MotionEvent e) {
                View childView = recyclerView.findChildViewUnder(e.getX(), e.getY());

                if (childView != null && mListener != null) {
                    mListener.onItemLongClick(childView, recyclerView.getChildAdapterPosition(childView));
                }
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
        View childView = view.findChildViewUnder(e.getX(), e.getY());

        if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
            mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
        }

        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) {
    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
    }
}

然后你可以这样使用它:

recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(getActivity(), recyclerView, new RecyclerItemClickListener.OnItemClickListener() {
    @Override
    public void onItemClick(View view, int position) {
        // ...
    }

    @Override
    public void onItemLongClick(View view, int position) {
        // ...
    }
}));

在适配器类中添加接口。

public interface SelectedUser{

    void selectedUser(UserModel userModel);

}

在mainactivity中实现你的接口并覆盖selectedUser方法。

@Override
public void selectedUser(UserModel userModel) {

    startActivity(new Intent(MainActivity.this, SelectedUserActivity.class).putExtra("data",userModel));

}

完整的教程在这里加上源代码。 Recyclerview与clicklistener和searchview

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。

通常你在CardView中有多个元素，所以你需要一个布局视图来包装和组织它们。你可以添加一个OnClickListener到那个布局视图。1. 添加一个id到你的布局。在这个例子中是线性布局

<android.support.v7.widget.CardView
 .....>

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/card_view_linearLayout">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="name"
            android:id="@+id/card_view_name" />

        ...

    </LinearLayout>

</android.support.v7.widget.CardView>

2美元。在你的内部ViewHolder类中获取布局视图。

public static class ViewHolder extends RecyclerView.ViewHolder{
    private TextView nameView;
    ...
    private LinearLayout linearLayout;
    public ViewHolder(View itemView) {
        super(itemView);
        nameView = (TextView)itemView.findViewById(R.id.card_view_name);
        ...
        linearLayout = (LinearLayout)itemView.findViewById(R.id.card_view_linearLayout);
    }
}

3美元。将监听器添加到onBindViewHolder中的布局中，并使用回调将数据发送到活动或片段(未测试)。

@Override
public void onBindViewHolder(TrackAdapter.ViewHolder holder, final int position) {
    String str = mStringList.get(position);

    holder.nameView.setText(str);
    ...
    holder.linearLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            callback.itemCallback(mStringList.get(position));
        }
    });
}

如何使用回调是另一个故事

这里有一个简单明了的方法是添加到您的ReacyclerView ViewHolder

public static class MyViewholder extends RecyclerView.ViewHolder {

    public MyViewholder(View itemView) {
        super(itemView);

        itemView.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d("Tag", "onClick：" + getAdapterPosition());
            }
        });

    }
}

getAdapterPosition()返回当前被单击项的位置
