Unable to show popup menu in Adapter in Android
<p>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.</p>

<p>In onBindViewHolder of RecyclerViewAdapter, I am showing pop up menu like this</p>

<pre><code>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;
            }
</code></pre>

<p>But when I fire long click event, it is giving me this error.</p>

<p>I tried this way as well.</p>

<pre><code>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;
            }
        });
</code></pre>

<p>I just got the same error. This is my menu xml file</p>

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

    &lt;item android:id="@+id/m_item_edit_com" android:title="Edit" app:showAsAction="ifRoom|withText" /&gt;
    &lt;item android:id="@+id/m_item_delete_com" android:title="Delete" app:showAsAction="ifRoom|withText" /&gt;
&lt;/menu&gt;
</code></pre>

<p>What is wrong with my code?</p>
