我创建了一个类，用于在 RecyclerView 内的 CardView 中显示员工详细信息。新的要求是点击时显示卡片的弹出窗口。所以我添加了 setOnClickListener 并且它工作正常（我在日志中得到了卡名）。但是如何通过单击打开弹出窗口呢？其实我是android新手
public class EmployeeCardAdapter extends RecyclerView.Adapter<EmployeeCardAdapter.ViewHolder> {
private Context context;
private EmployeeBean employeeBean;
private ArrayList<EmployeeBean> employeeList;
public EmployeeCardAdapter(Context context, ArrayList<EmployeeBean> 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。但这里我使用的是片段。我设计了一个弹窗布局如下

我可以从上面的适配器类中以弹出窗口的形式打开此布局吗？
如果您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);
}
