Get focused View from ViewPager

Question

i use the ViewPager for switching views with left/right swipe.

The ViewPager needs an Adapter, so I\'ve built this one:

public class ListViewPagerAda         


        

Answer 1

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());

Answer 2

Am I missing something? There's only ever 3 children inside the ViewGroup, so it boils down to:

int current = viewPager.getCurrentItem();
int childCount = viewPager.getChildCount();
// If there's a single page or we're at the beginning, return the first view
if (childCount == 1 || current == 0) {
  return viewPager.getChildAt(0);
} else { //For any other case, we want the second child. This is either the last page or the page in the middle for any other case.
  return viewPager.getChildAt(1);
}

Answer 3

Inside your FragmentStatePagerAdapter:

    private View mCurrentView;

    @Override
    public void setPrimaryItem(ViewGroup container, int position, Object object) {
        Fragment f = (Fragment) object;
        mCurrentView = f.getView();
    }

Answer 4

You can use:

 viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {
            Log.i("maylonsales", "onPageSelected position " + position);
        }

        @Override
        public void onPageScrollStateChanged(int state) {

        }
    });

Answer 5

Try this:

public View getCurrentView(ViewPager pager) {
    for (int i = 0; i < pager.getChildCount(); i++) {
        View child = pager.getChildAt(i);
        if (child.getX() <= pager.getScrollX() + pager.getWidth() && 
            child.getX() + child.getWidth() >= pager.getScrollX() + pager.getWidth()) {
            return child;
         }
     }
     return getChildAt(0);
}
