Get focused View from ViewPager

It is possible to save the currently active object (View, Fragment, ...) by overriding PagerAdapter.setPrimaryItem method. For example:

private View mCurrentView;

@Override
public void setPrimaryItem(ViewGroup container, int position, Object object) {
    mCurrentView = (View)object;
}

You have to register a listener to your ViewPager :

pager.setOnPageChangeListener(new MyPageChangeListener()); 

You have to customize the listener by extending a stub listener:

private int focusedPage = 0;
private class MyPageChangeListener extends ViewPager.SimpleOnPageChangeListener {
    @Override
    public void onPageSelected(int position) {
        focusedPage = position;
    }
}

I found this by looking at the ViewPager.java source code in the compatibility library. I read that we can do more, for example catch onPageScrollStateChanged.

To build the adapter, I used the code on this blog post. You might want to have a look.

You can add a tag to the created view in the instantiateItem method:

view.setTag(position);

Later you can access the current selected view by:

mPager.findViewWithTag(mPager.getCurrentItem());
