Question

Im using action bar compability library. Im trying to open the options menu from a button with openOptionsMenu() function but it does nothing.

Menu shows as usual wh

Answer 1

I cannot understand the forcing blocking Menu button usage as well. However, the following trick helped me with showing a menu on "restricted" types of devices.

First of all we need to define, whether we require the following hack or not.

boolean requireDirtyMenuButtonHack = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB && (activity.getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_XLARGE) > 0;

Then:

protected final OnClickListener mMenuButtonClickListener = new OnClickListener() {

    @Override
    public void onClick(View v) {
        if (requireDirtyMenuButtonHack) {
            Configuration config = getContext().getResources().getConfiguration();
            config.screenLayout &= ~Configuration.SCREENLAYOUT_SIZE_XLARGE;
            config.screenLayout |= Configuration.SCREENLAYOUT_SIZE_LARGE;
        }

        getActivity().openOptionsMenu();
    }
};

Don't forget to cleanup! (don't know if it's neccessary, but better to play kind)

public void onPrepareOptionsMenu(Menu menu) {
    if (requireDirtyMenuButtonHack) {
        Configuration config = getContext().getResources().getConfiguration();
        config.screenLayout &= ~Configuration.SCREENLAYOUT_SIZE_LARGE;
        config.screenLayout |= Configuration.SCREENLAYOUT_SIZE_XLARGE;
    }

    //do the preparing...
}
