我的方式

活动课上:

    public class MyActivity extends AppCompatActivity implements EmployeeAdapter.ClickListener {
    ...
    @Override
    public void onClick(int position) { ... }
    ...
    }

适配器类:

    public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
    ...
    @Override
    public void onBindViewHolder(){
         holder.textView1.setOnClickListener(v -> clickListener.onClick(position));
    }
    ...
    public interface ClickListener {
        void onClick(int position);
    }
    ...
    }

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);
}

这就是我最后需要的东西，以防有人发现它有用:

public static class ViewHolder extends RecyclerView.ViewHolder {

    public ViewHolder(View item) {

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

    }
}

你可以很容易地在ViewHolder类中定义setOnClickListener，如下所示:

public class ViewHolder extends RecyclerView.ViewHolder {
    TextView product_name;

    ViewHolder(View itemView) {
        super(itemView);
        product_name = (TextView) itemView.findViewById(R.id.product_name);
        itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int itemPosition = getLayoutPosition();
                Toast.makeText(getApplicationContext(), itemPosition + ":" + String.valueOf(product_name.getText()), Toast.LENGTH_SHORT).show();
            }
        });
    }
}

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));

}

对于kotlin句柄，根据Jacobs的回答单击RecyclerView答案

创建类RecyclerItemClickListener:

class RecyclerItemClickListener(context: Context, recyclerView: RecyclerView, listner: OnItemClickListener) : RecyclerView.OnItemTouchListener {

    var mGestureDetector: GestureDetector
    var mListner: OnItemClickListener
    
    interface OnItemClickListener {
        fun onItemClick(view: View, position: Int)
        fun onLongItemClick(view: View, position: Int)
    }

    init {
        this.mListner = listner
        mGestureDetector = GestureDetector(context, object : GestureDetector.SimpleOnGestureListener() {
            override fun onSingleTapUp(e: MotionEvent?): Boolean = true
            
            override fun onLongPress(e: MotionEvent?) {
                val child: View? = recyclerView.findChildViewUnder(e!!.getX(), e.getY())
                if (child != null && mListner != null) {
                    mListner.onLongItemClick(child, recyclerView.getChildAdapterPosition(child))
                }
            }
        })
    }

    override fun onTouchEvent(rv: RecyclerView, e: MotionEvent) = Unit

    override fun onInterceptTouchEvent(view: RecyclerView, e: MotionEvent): Boolean {
        val childView: View? = view.findChildViewUnder(e!!.getX(), e.getY())
        if (childView != null && mListner != null && mGestureDetector.onTouchEvent(e)) {
            mListner.onItemClick(childView, view.getChildAdapterPosition(childView))
            return true
        }
        return false
    }

    override fun onRequestDisallowInterceptTouchEvent(disallowIntercept: Boolean) = Unit

}

点击Any RecyclerView(在活动/片段内):

recyclerView.addOnItemTouchListener(
    RecyclerItemClickListener(this, recyclerView, object : RecyclerItemClickListener.OnItemClickListener {
        override fun onItemClick(view: View, position: Int) {
            // TODO catch click
        }

        override fun onLongItemClick(view: View, position: Int) {
            // TODO catch click
        }
    })
)
