Android Viewpager Get the Current View

Android ViewPager get the current View

I've figured it out. What I did was to call setTag() with a name to all Views/ListViews, and just call findViewWithTag(mytag), mytag being the tag.

Unfortunately, there's no other way to solve this.

Getting current view from ViewPager

You can try something like this -

@Override
public Object instantiateItem(ViewGroup container, int position) {
    LayoutInflater inflater;
    if(position != 10){
            inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
     itemView = inflater.inflate(R.layout.viewpager_item, container,
            false);
      itemView.setTag("View"+position);

    } else {
        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         itemView = inflater.inflate(R.layout.results, container,
                false);
    }
    container.addView(itemView);
    return itemView ;
}

And when you need the current view-

View myView = pager.findViewWithTag("View"+pager.getCurrentItem());

Getting the current Fragment instance in the viewpager

by selecting an option, I need to update the fragment that is
currently visible.

A simple way of doing this is using a trick related to the FragmentPagerAdapter implementation:

case R.id.addText:
     Fragment page = getSupportFragmentManager().findFragmentByTag("android:switcher:" + R.id.pager + ":" + ViewPager.getCurrentItem());
     // based on the current position you can then cast the page to the correct 
     // class and call the method:
     if (ViewPager.getCurrentItem() == 0 && page != null) {
          ((FragmentClass1)page).updateList("new item");     
     } 
return true;

Please rethink your variable naming convention, using as the variable name the name of the class is very confusing(so no ViewPager ViewPager, use ViewPager mPager for example).

How do you get the current page number of a ViewPager for Android?

in the latest packages you can also use

vp.getCurrentItem()

or

vp is the viewPager ,

pageListener = new PageListener();
vp.setOnPageChangeListener(pageListener);

you have to put a page change listener for your viewPager. There is no method on viewPager to get the current page.

private int currentPage;

    private static class PageListener extends SimpleOnPageChangeListener{
            public void onPageSelected(int position) {
                Log.i(TAG, "page selected " + position);
                   currentPage = position;
        }
    }

Get Current Position of ViewPager

You shoul set text onPageSelected.

  viewPager.setOnPageChangeListener(new OnPageChangeListener() {

        @Override
        public void onPageSelected(int arg0) {
            // TODO Auto-generated method stub
            System.out.println("Current position=="+num);
            textView.setText((arg0+1)+" of "+ images.size());
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {
            // TODO Auto-generated method stub

            System.out.println("onPageScrolled");
        }

        @Override
        public void onPageScrollStateChanged(int num) {
            // TODO Auto-generated method stub

        }
    });

Getting the current position of a ViewPager

Create a listener and set it on your viewpager:

/**
 * Get the current view position from the ViewPager by
 * extending SimpleOnPageChangeListener class and adding your method
 */
public class DetailOnPageChangeListener extends ViewPager.SimpleOnPageChangeListener {

    private int currentPage;

    @Override
    public void onPageSelected(int position) {
        currentPage = position;
    }

    public final int getCurrentPage() {
        return currentPage;
    }
}

ViewPager2, get current page viewholder

You can do something like this

(viewPager2.get(0) as RecyclerView).findViewHolderForAdapterPosition(position)

or

(viewPager2.get(0) as RecyclerView).layoutManager.findViewByPosition(position)
