Unable to show popup menu in Adapter in Android

Question

I am developing an Android app. In my app, I am showing pop up menu in Recycler view adapter. But it is giving me error.

In onBindViewHolder of RecyclerViewAdapter, I am showing pop up menu like this

viewHolder.container.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View view) {
                PopupMenu popupMenu = new PopupMenu(context,view);
                popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    @Override
                    public boolean onMenuItemClick(MenuItem item) {
                        return false;
                    }
                });
                popupMenu.inflate(R.menu.menu_mm_comment_item);

                popupMenu.show();
                return true;
            }

But when I fire long click event, it is giving me this error.

I tried this way as well.

viewHolder.container.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View view) {
                PopupMenu popupMenu = new PopupMenu(context,view);
                popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                @Override
                        public boolean onMenuItemClick(MenuItem item) {
                        return false;
                   }
                });
                popupMenu.getMenuInflater().inflate(R.menu.menu_mm_comment_item,popupMenu.getMenu());

                popupMenu.show();
                return true;
            }
        });

I just got the same error. This is my menu xml file

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item android:id="@+id/m_item_edit_com" android:title="Edit" app:showAsAction="ifRoom|withText" />
    <item android:id="@+id/m_item_delete_com" android:title="Delete" app:showAsAction="ifRoom|withText" />
</menu>

What is wrong with my code?

Answer 1

Finally found the solution to this problem, though I have no explanation why this solution works.

With the following import I always had the error:

import android.support.v7.widget.PopupMenu;

It works fine with the following import:

import android.widget.PopupMenu;
