app:showAsAction ifRoom is not working on appcompat action bar

Question

I have an action bar with the following menu items;

Answer 1

In my case I had to add a few lines to onCreateOptionsMenu.

Android Studio didn't let me use android:showAsAction="ifRoom" while using appCompat.

app:showAsAction="ifRoom" wasn't working and I removed it without problems.

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater  inflater = getMenuInflater();
        inflater.inflate(R.menu.menu, menu);
        for (int i = 0; i < menu.size(); i++) {
            menu.getItem(i).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
        }
        return super.onCreateOptionsMenu(menu);
    }
