如何从适配器类打开弹出窗口

我创建了一个类,用于在RecyclerView中的CardView中显示员工详细信息.新要求是在点击时显示卡片的弹出窗口.所以我添加了setOnClickListener,它工作正常(我在Log中得到了卡片名称).但是如何通过此点击打开弹出窗口？其实我是android的新手

public class EmployeeCardAdapter extends RecyclerView.Adapter {

private Context context;
private EmployeeBean employeeBean;
private ArrayList employeeList;



public EmployeeCardAdapter(Context context, ArrayList employeeList){
    this.context = context;
    this.employeeList = employeeList;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

   View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.employee_card, parent, false);
    ViewHolder viewHolder = new ViewHolder(v);
    return viewHolder;
}

@Override
public void onBindViewHolder(ViewHolder viewHolder, int position) {

    EmployeeBean employeeBean = employeeList.get(position);
    viewHolder.employeeCardTitle.setText(employeeBean.getName());
    viewHolder.employeeName.setText(employeeBean.getName());
    viewHolder.employeeQualification.setText(employeeBean.getQualification());
    viewHolder.employeeExperiance.setText(employeeBean.getExperiance());

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


public static class  ViewHolder extends RecyclerView.ViewHolder{

    public TextView employeeCardTitle;
    public TextView employeeName;
    public TextView employeeQualification;
    public TextView employeeExperiance;

    public View view;
    public ClipData.Item currentItem;
    public ViewHolder(final View itemView) {
        super(itemView);
        employeeCardTitle = (TextView)itemView.findViewById(R.id.employee_card_title);
        employeeName = (TextView)itemView.findViewById(R.id.employee_name);
        employeeQualification = (TextView)itemView.findViewById(R.id.employee_Qualification);
        employeeExperiance = (TextView)itemView.findViewById(R.id.employee_experiance);

        itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {



            }
        });
    }
}

}

我搜索了很多教程,但每个教程都是从Activity类打开弹出窗口.但在这里我使用片段.我设计了一个弹出窗口布局如下

我可以从上面的适配器类打开这个布局作为弹出窗口吗？

如果你想在特定位置打开弹出窗口而不是需要在showasdropdown中给出位置,请尝试此操作.

public void showPopup(View view) {
        View popupView = LayoutInflater.from(getActivity()).inflate(R.layout.popup_, null);
        final PopupWindow popupWindow = new PopupWindow(popupView, WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
        Button btnDismiss = (Button) popupView.findViewById(R.id.btn_dismiss);
        btnDismiss.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                popupWindow.dismiss();
            }
        });

        popupWindow.showAsDropDown(popupView, 0, 0);
    }
