Android ActionBarSherlock style selected action item

Question

I have a ViewPager AND each page displays a photo. I show a split ActionBar with like/dislike action that are used so user can vote 'like' the photo or 'dislike' it.

I successfully implemented the vote feature for each photo.

Problem:

How do I style the selected vote for each photo? In other words, how can I mange the MenuItem icon based on the current state of the photo?

Answer 1

You should create a boolean to detect when a photo is liked, then call setIcon on your MenuItem.

final MenuItem liked = YOUR_MENU.findItem(THE_LIKED_ACTION_ID);
    if (isLiked()) {
        liked.setIcon(YOUR_LIKED_DRAWABLE);
    } else {
        liked.setIcon(YOUR_DEFAULT_LIKED_DRAWABLE);
    }

mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
        @Override
        public void onPageSelected(int position) {
            invalidateOptionsMenu();
        }
    });
