android - ViewPager disable swiping to a certain direction

Question

I want to disable the swiping, but only to the right side. I found a working solution in this answer. Unfortunately, this copies the whole ViewPager source to achieve the goal. Is there any methods just inheriting the existing class and not duplicating?

I'm not sure this is exactly what you need: I needed a viewpager for a wizard with a max page that the user can't pass it.

At the end the solution was in the adapter. I changed the count of the PagerAdapter and this way blocks the user from passing the max page:

@Override
public int getCount() {
    return mProgress; //max page + 1
}

When the user progresses to the next page:

private void setWizardProgress(int progress) {
    if(progress > mProgress) {
        mProgress = progress;
        mWizardPagerAdapter.notifyDataSetChanged();
    }
}

This way when the user is at max page he can't scroll to the right.
