AppCompat PopUp menu RuntimeException

Question

I am using following class to create iconized popup menu:

public class IconizedMenu implements MenuBuilder.Callback, MenuPresenter.Callback {
    private Context mContext;
    private MenuBuilder mMenu;
    private View mAnchor;
    private MenuPopupHelper mPopup;
    private OnMenuItemClickListener mMenuItemClickListener;

     */
    public interface OnDismissListener {
        /**
         * Called when the associated menu has been dismissed.
         *
         * @param menu The PopupMenu that was dismissed.
         */
        public void onDismiss(IconizedMenu menu);
    }

        mAnchor = anchor;
        mPopup = new MenuPopupHelper(context, mMenu, anchor);

        mPopup.setForceShowIcon(true);
    }

        public boolean onMenuItemClick(MenuItem item);
    }

}

However if I try to run it on lolipop it causes error. It works fine on devices with API level < 21. Here is the logcat:

activity which uses this extends Activity, not ActionBarActivity. Any ideas why is it generating an error?

Thanks in forward

EDIT: I have tried using default appCompat PopUp menu (so its without icons) and it is throwing same error. Any ideas?

Answer 1

If you are using Appcompat and lollipop try adding new style

<style name="MyPopupMenu" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:popupBackground">#0F213F</item>
    <item name="android:disabledAlpha">0.5</item>
</style>

and create the popup menu

Context wrapper = new ContextThemeWrapper(context, R.style.MyPopupMenu);
            PopupMenu popup = new PopupMenu(wrapper, view);

Answer 2

In this case MenuPopupHelper.MenuAdapter#getView() try to inflate ITEM_LAYOUT = R.layout.abc_popup_menu_item_layout and during this process android.support.v7.internal.view.menu.ListMenuItemView created and require R.styleable.MenuView (look inside to find - declare-styleable name="MenuView") where attribute at index 6 is attr name="android:itemIconDisabledAlpha" this mean that no this attribute defined in application theme. Required attribute defined in <style name="Theme"> for any platform as <item name="disabledAlpha">0.5</item> this is link.

To use default value just extend application theme by one of the themes that extends <style name="Theme">.

I recommend following solution:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>

or any other Theme.AppCompat with NoActionBar if you want to use Toolbar for older than v21 platforms with all new features available as replacement of ActionBar component.

But actually feel free to use other themes like Holo or Material if it's really required.

Good luck!

And feel free to ask.
