Popup Menu in custom ListView

Issue

What I want to achieve:

I have a custom ListView adapter. To each Listitem I want to add a popup menu, pretty similar to the ListView in the current Google Play application.

This is what I tried: Most of my code comes from this Android sample samples\android-19\ui\ActionBarCompat-ListPopupMenu

CustomFragmentPageAdapter.java:

// create new fragment
mCustomFragment = CustomFragment.newInstance(position);

CustomFragment.java

public class CustomFragment extends ListFragment implements View.OnClickListener{

...

@Override
public void onClick(final View v) {
    v.post(new Runnable() {
        @Override
        public void run() {
            showPopupMenu(v);
        }
    });
}

private void showPopupMenu(View view) {

    PopupMenu popup = new PopupMenu(getActivity(), view);

    popup.getMenuInflater().inflate(R.menu.popup_menu, popup.getMenu());

    popup.show();
}

CustomArrayAdapter:

public class CustomAdapter extends ArrayAdapter<WatchListPlayerItem> {
    ...    
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final int pos = position;

        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        final View rowView = inflater.inflate(R.layout.watch_list_row, parent, false);

        View popupButton = rowView.findViewById(R.id.imgPopUp);

        popupButton.setTag(getItem(position));

        popupButton.setOnClickListener(mFragment);

        return rowView;
    }
}

popup_menu.xml:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/install"
        android:title="Install" />
    <item
        android:id="@+id/addtowishlist"
        android:title="Add to wishlist" />
</menu>

Logcat output:

java.lang.RuntimeException: Failed to resolve attribute at index 6
            at android.content.res.TypedArray.getLayoutDimension(TypedArray.java:603)
            at android.view.ViewGroup$LayoutParams.setBaseAttributes(ViewGroup.java:6423)
            at android.view.ViewGroup$MarginLayoutParams.<init>(ViewGroup.java:6591)
            at android.widget.FrameLayout$LayoutParams.<init>(FrameLayout.java:735)
...

The error is thrown at popup.show() in my CustomFragment.

This error is clearly driving me crazy and ANY help to solve this issue is highly appreciated!

Solution

I finally found the solution to my problem, eventhough 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;

I tested the code provided by Ric (Thanks for the great help!) and my own. Both are working now. Maybe someone has an explanation why the import matters in this case.
