How can add popupMenu to items of listView in Android?

Question

I want to show popupMenu onLongClick in Android, so I write:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    listView = (ListView) findViewById(R.id.listView);
    adapter = new MyAdapter(getApplicationContext());

}

@Override
protected void onResume() {
    super.onResume();
    connectToDatabase();
}

private void connectToDatabase() {
    //Create database
        listView.setAdapter(adapter);
    }

My Adapter:

        @Override
    public View getView(final int position, View convertView, final ViewGroup parent) {
        final MyHolder holder;
        if (convertView == null) {
            convertView = layoutInflater.inflate(R.layout.list_row, null);
            holder = new MyHolder();
            holder.vocabs = (TextView) convertView.findViewById(R.id.textViewVocabs);
            holder.points = (TextView) convertView.findViewById(R.id.textViewPoints);
            holder.tick = (ImageButton) convertView.findViewById(R.id.tick);
            holder.cross = (ImageButton) convertView.findViewById(R.id.cross);
            convertView.setTag(holder);
        } else {
            holder = (MyHolder) convertView.getTag();
        }

        holder.id = id.get(position);
        holder.vocabs.setText(vocabs.get(position));
        holder.points.setText(points.get(position) + "");

        holder.tick.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Toast.makeText(parent.getContext(), "Yes... :D ... You learn it :D", Toast.LENGTH_SHORT).show();
                points.set(position, points.get(position) + 1);
                database.execSQL("UPDATE VOCABS SET POINTS=" + points.get(position) + " WHERE ID=" + id.get(position) + ";");
                notifyDataSetChanged();
            }
        });

        holder.cross.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Toast.makeText(parent.getContext(), "Yes... :D ... You learn it :D", Toast.LENGTH_SHORT).show();
                if (points.get(position) != 0) {
                    points.set(position, points.get(position) - 1);
                    database.execSQL("UPDATE VOCABS SET POINTS=" + points.get(position) + " WHERE ID=" + id.get(position) + ";");
                }
                notifyDataSetChanged();
            }
        });

        convertView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(parent.getContext(), means.get(position), Toast.LENGTH_LONG).show();
            }
        });

        final View finalConvertView = convertView;
        convertView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                //popup-menu for delete item.
                PopupMenu popupMenu = new PopupMenu(parent.getContext(),finalConvertView);
                popupMenu.getMenuInflater().inflate(R.menu.popup_menu, popupMenu.getMenu());
                popupMenu.show();

                popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    @Override
                    public boolean onMenuItemClick(MenuItem item) {
                        if (item.getTitle().equals("Delete")) {
                            database.execSQL("DELETE FROM VOCABS WHERE ID=" + holder.id + ";");
                            id.remove(position);
                            vocabs.remove(position);
                            means.remove(position);
                            points.remove(position);
                            notifyDataSetChanged();
                        }
                        return false;
                    }
                });
                //Toast.makeText(parent.getContext(), "onLongClickFunction! " + position, Toast.LENGTH_LONG).show();
                return false;
            }
        });
        return convertView;
    }

I work with Itellij IDEA 13.1.4. I add appcompat to supports popup_Menu on APIs older than 11. now when I run application, Everythings are ok. but when Long Click on an item in the listView get below Error:

What is wrong???

Answer 1

I suspect you're not getting the correct view when calling PopupMenu constructor.

Change code FROM:

PopupMenu popupMenu = new PopupMenu(parent.getContext(),finalConvertView);

TO:

PopupMenu popupMenu = new PopupMenu(parent.getContext(), v);

I admit maybe it is the same view but depending on the layout design. The suggested code under TO is more accurate. The View parameter v points to a certain row item in ListView.

Please post your menu xml R.menu.popup_menu also.
