Getting the current position of a ViewPager

I know with the Gallery widget I was able to use getSelectedItemPosition(); to retrieve the current position, however it doesnt seem ViewPager has that.

I know I can setup a listener and retrieve the position when the page is switched. But I want the current view position.

Solution 1:

You can use:

mViewPager.getCurrentItem()

Solution 2:

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;
    }
}

Solution 3:

Update 2019

Now you can set addOnPageChangeListener on View Pager to Observe change in Page position.

Since you wanted to setup a listener and retrieve the position when the page is switched

mViewPager.addOnPageChangeListener(object : OnPageChangeListener {
            override fun onPageScrollStateChanged(state: Int) {}
            override fun onPageScrolled(position: Int, positionOffset: Float, positionOffsetPixels: Int) {}

            override fun onPageSelected(position: Int) {
                pagePosition.setText("" + position + "/" + galleryAdapter!!.count)
            }
        })
