对我来说，最干净的方法就是这个。

适配器的构造函数

private class EnvironmentTypeRecyclerViewAdapter extends RecyclerView.Adapter<EnvironmentTypeRecyclerViewAdapter.ViewHolder>
{
     private final EnvironmentTypeRecyclerViewAdapterListener mEnvironmentTypeRecyclerViewAdapterListener;
     private List<Environment> mEnvironmentsData;

     public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener
     {
         public ViewHolder(View v)
         {
             super(v);
             v.setOnClickListener(this);

         }

         @Override
         public void onClick(View v)
         {
              Environment environment = mEnvironmentsData.get(getAdapterPosition());
              if (mEnvironmentTypeRecyclerViewAdapterListener != null && environment != null) {
                      mEnvironmentTypeRecyclerViewAdapterListener.onListItemSelected(environment);      
              }
        }

        public EnvironmentTypeRecyclerViewAdapter(List<SmallCellEnvironment> environments, EnvironmentTypeRecyclerViewAdapterListener environmentTypeRecyclerViewAdapterListener)
        {
            mEnvironmentTypeRecyclerViewAdapterListener = environmentTypeRecyclerViewAdapterListener;
            mEnvironmentsData = environments;
        }
}

链接接口

private interface EnvironmentTypeRecyclerViewAdapterListener
{
    void onListItemSelected(Environment environment);
}

我是这样做的，没有不必要的类、检测器等。适配器中的简单代码。特别是针对longClick的更好解决方案。

public class PasswordAdapter extends RecyclerView.Adapter<PasswordAdapter.ViewHolder> {
    private final ClickListener clickListener;

    public PasswordAdapter(ClickListener clickListener) {
         this.clickListener = clickListener;
    }

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener {
        TextView name;

        public ViewHolder(View itemView) {
            super(itemView);
            itemView.setOnClickListener(this);
            itemView.setOnLongClickListener(this);
            name = (TextView) itemView.findViewById(R.id.card_name);
        }

        @Override
        public void onClick(View v) {
            int position = getBindingAdapterPosition();
            if (position >= 0) {
                clickListener.onItemClick(position, v);
            }
        }

        @Override
        public boolean onLongClick(View v) {
            int position = getBindingAdapterPosition();
            if (position >= 0) { 
                clickListener.onItemLongClick(position, v);
                return true;
            }
            return false;
        }
    }

    public interface ClickListener {
        void onItemClick(int position, View v);
        void onItemLongClick(int position, View v);
    }
}

然后在片段或活动中，点击:

PasswordAdapter mAdapter = new PasswordAdapter(
    new PasswordAdapter.ClickListener() {
        @Override
        public void onItemClick(int position, View v) {
            Log.d(TAG, "onItemClick position: " + position);
        }

        @Override
        public void onItemLongClick(int position, View v) {
            Log.d(TAG, "onItemLongClick pos = " + position);
        }
    }
);

太简单和有效了。

而不是实现接口视图。OnClickListener内的视图持有人或创建和接口和实现接口在您的活动- 我使用这段代码简单的OnClickListener实现。

public static class SimpleStringRecyclerViewAdapter
            extends RecyclerView.Adapter<SimpleStringRecyclerViewAdapter.ViewHolder> {

        // Your initializations goes here...
        private List<String> mValues;

        public static class ViewHolder extends RecyclerView.ViewHolder {

            //create a variable mView
            public final View mView;

            /*All your row widgets goes here
            public final ImageView mImageView;
            public final TextView mTextView;*/

            public ViewHolder(View view) {
                super(view);
                //Initialize it here
                mView = view;

                /* your row widgets initializations goes here
                mImageView = (ImageView) view.findViewById(R.id.avatar);
                mTextView = (TextView) view.findViewById(android.R.id.text1);*/
            }
        }

        public String getValueAt(int position) {
            return mValues.get(position);
        }

        public SimpleStringRecyclerViewAdapter(Context context, List<String> items) {

            mBackground = mTypedValue.resourceId;
            mValues = items;
        }

        @Override
        public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View view = LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.list_item, parent, false);
            view.setBackgroundResource(mBackground);
            return new ViewHolder(view);
        }

        @Override
        public void onBindViewHolder(final ViewHolder holder, int position) {
            holder.mBoundString = mValues.get(position);
            holder.mTextView.setText(mValues.get(position));

            //Here it is simply write onItemClick listener here
            holder.mView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Context context = v.getContext();
                    Intent intent = new Intent(context, ExampleActivity.class);

                    context.startActivity(intent);
                }
            });
        }

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

我已经看了所有的答案，并不是很满意。我找到了更简单快捷的方法。想分享给未来的读者。

选择单个回收项目中的任何视图。 获取这个View的父视图(确保你施放了合适的ViewGroup) 将onClickListener设置为这个父节点。

示例代码(它是在适配器的onBindViewHolder方法中编写的):

@Override
public void onBindViewHolder(@NonNull final ViewHolder holder, final int position) {

    ConstraintLayout parent = (ConstraintLayout) holder.title.getParent();
    parent.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(context, "Clicked recycler view item at position " + position, Toast.LENGTH_SHORT).show();
        }
    });
}

如果你想在个别项目上捕捉点击事件，那么只需在ViewHolder类中实现OnClickListener，然后在个别视图或整个itemView上设置点击侦听器。

下面的例子说明了同样的情况

public  class ContactViewHolder extends RecyclerView.ViewHolder implements OnClickListener
    {
        TextView txt_title,txt_name,txt_email;

        public ContactViewHolder(View itemView) 
        {
            super(itemView);
            txt_title = (TextView)itemView.findViewById(R.id.txt_title);
            txt_name  = (TextView)itemView.findViewById(R.id.txt_name);
            txt_email = (TextView)itemView.findViewById(R.id.txt_email);

            txt_name.setOnClickListener(this);
            txt_email.setOnClickListener(this);
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            if(v == itemView)
            {
                Toast.makeText(RecyclerDemoActivity.this, "Visiting Card Clicked is ==>"+txt_name.getText(), Toast.LENGTH_SHORT).show();
            }

            if(v == txt_name)
            {
                Toast.makeText(RecyclerDemoActivity.this, "Name ==>"+txt_name.getText(), Toast.LENGTH_SHORT).show();
            }

            if(v == txt_email)
            {
                Toast.makeText(RecyclerDemoActivity.this, "Email ==>"+txt_email.getText(), Toast.LENGTH_SHORT).show();
            }
        }

    }
} 

nhaarman答案的Kotlin实现:

mRecyclerView.addOnItemTouchListener(object  : RecyclerItemClickListener(this, mRecyclerView,object :RecyclerItemClickListener.OnItemClickListener{
            override fun onItemClick(view: View, position: Int) {

            }

            override fun onLongItemClick(view: View?, position: Int) {

            }
}){})

RecyclerItemClickListener.java:

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


open class RecyclerItemClickListener(context: Context, recyclerView: RecyclerView, private val mListener: OnItemClickListener?) : RecyclerView.OnItemTouchListener {

    private var mGestureDetector: GestureDetector

    interface OnItemClickListener {
        fun onItemClick(view: View, position: Int)

        fun onLongItemClick(view: View?, position: Int)
    }

    init {
        mGestureDetector = GestureDetector(context, object : GestureDetector.SimpleOnGestureListener() {
            override fun onSingleTapUp(e: MotionEvent): Boolean {
                return true
            }

            override fun onLongPress(e: MotionEvent) {
                val child = recyclerView.findChildViewUnder(e.x, e.y)
                if (child != null && mListener != null) {
                    mListener.onLongItemClick(child, recyclerView.getChildAdapterPosition(child))
                }
            }
        })
    }

    override fun onInterceptTouchEvent(view: RecyclerView, e: MotionEvent): Boolean {
        val childView = view.findChildViewUnder(e.x, e.y)
        if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
            mListener.onItemClick(childView, view.getChildAdapterPosition(childView))
            return true
        }
        return false
    }

    override fun onTouchEvent(view: RecyclerView, motionEvent: MotionEvent) {}

    override fun onRequestDisallowInterceptTouchEvent(disallowIntercept: Boolean) {}
}
