Answer 1

This worked for me, my code is pretty similar to yours, and what I want to do is from a button in the action bar, open the overflow menu:

public boolean onOptionsItemSelected(MenuItem item) {  
        switch (item.getItemId()) {  
        case R.id.menu_home_about:  
            dialog = new Dialog(this);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setContentView(R.layout.customdialog);
            dialog.show();
            break;

            default:

        case R.id.menu_home_refresh:
            updateLists(true);
            break;

        case R.id.menu_home_menu:
            new Handler().postDelayed(new Runnable() {
                public void run() {                
                    openOptionsMenu();        
                }
            }, 0); 
            return true;

        }
        return false;  
    }

I was having the same problem trying to go around this openOptionsMenu thing on an app that I was doing that should run on Android 1.6 and up. Following the answer from Werner Van Belle I reached the conclusion that we could achieve a workaround to solve the problem. So I came up with the following code, it's always beatiful when people don't mark a method as final, so we can always override it. It's perfect if you don't want to give up on targeting your app to the latest api (android:targetSdkVersion="17"). I hope you guys like it. :)

@Override
public void openOptionsMenu() {

    Configuration config = getResources().getConfiguration();

    if((config.screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) 
            > Configuration.SCREENLAYOUT_SIZE_LARGE) {

        int originalScreenLayout = config.screenLayout;
        config.screenLayout = Configuration.SCREENLAYOUT_SIZE_LARGE;
        super.openOptionsMenu();
        config.screenLayout = originalScreenLayout;

    } else {
        super.openOptionsMenu();
    }
}

Answer 3

If you are using your custom toolbar, you can try:

toolBar.showOverflowMenu();

Answer 4

android:targetSdkVersion="10" in manifest helped me. openOptionsMenu() works as expected now on ICS+. In addition, there is "overflow" menu button appears at the bottom of screen (on device buttons panel).

ps: I use NoTitleBar theme (NoActionBar for sdk 11 and higher) +ViewPagerIndicator by Jake Wharton.

Answer 5

I'm not sure how relevant this is, but this forum post I found seems to be answerring the same question you have.

I hope this post is relevant enough to solve your problem.

Good luck!

Answer 6

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...
}
