I created a class for showing employee details in a CardView inside a RecyclerView . New requirement is to show a popup window of card while clicking. So I added setOnClickListener and it works fine(I got card name in Log). But how do I open a popup window from this click? Actually am a newbie in android
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) {
}
});
}
}
}

Can I open this layout as a popup window from above adapter class ??
Once try this if you wants to open popup window at particular position than you need give position in showasdropdown.
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);
}

LayoutInflater inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.popup_compare,null);
AlertDialog.Builder alertbox = new AlertDialog.Builder(v.getRootView().getContext());
alertbox.setMessage("No Internet Connection");
alertbox.setView(layout);
alertbox.setNeutralButton("OK",new DialogInterface.OnClickListener() {public void onClick(DialogInterface arg0,int arg1) {
//to do
}});
alertbox.show();
