Make ViewPager snap with shorter drag

Question

Is there any way to make the support package ViewPager snap to the next page with a shorter drag? The default behaviour seems to be that even if I drag almost 75% the page still

Answer 1

Here is my code used in Librera Reader

public class MyViewPager extends ViewPager {

  public MyViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
        initMyScroller();
    }

    private void initMyScroller() {
        try {
            Class viewpager = ViewPager.class;
            Field scroller = viewpager.getDeclaredField("mScroller");
            scroller.setAccessible(true);
            scroller.set(this, new MyScroller(getContext())); // my liner scroller

            Field mFlingDistance = viewpager.getDeclaredField("mFlingDistance");
            mFlingDistance.setAccessible(true);
            mFlingDistance.set(this, Dips.DP_10);//10 dip short drag

            Field mMinimumVelocity = viewpager.getDeclaredField("mMinimumVelocity");
            mMinimumVelocity.setAccessible(true);
            mMinimumVelocity.set(this, 0); //0 velocity

        } catch (Exception e) {
            LOG.e(e);
        }

    }

    public class MyScroller extends Scroller {
        public MyScroller(Context context) {
            super(context, new LinearInterpolator()); // my LinearInterpolator
        }

        @Override
        public void startScroll(int startX, int startY, int dx, int dy, int duration) {
            super.startScroll(startX, startY, dx, dy, 175);//175 duration
        }
    }

 }
