popupmenu - Android setIcon function for Popup Menu not displaying my drawable

Question

I'm trying to dynamically create a Popup Menu using Android's built-in PopupMenu class. No matter what I try, I'm unable to get the setIcon function to display anything. I've pared down my code to a pretty simple example:

public void showPopupMenu(View v) {
    popupMenu = new PopupMenu(this, v);
    popupMenu.setOnMenuItemClickListener(this);
    MenuItem menuItem = popupMenu.add("Menu Item 1");
    menuItem.setIcon(DrawableResource);
    popupMenu.show();
}

The menu shows up with only the text of the menu item. The resolution of the drawable is 40x40. If I try the same thing from XML, the icon shows up just fine. Any help figuring out what might be wrong is appreciated.

I note an error in the value passed to the setIcon method. You need to get your drawable resource image by doing

menuItem.setIcon(R.drawable.NameOfYourDrawableFile);

For instance, if the name of your drawable resource image is image.png, then you should do:

menuItem.setIcon(R.drawable.image);
