解决方法：

只需要自定义一个类去继承ViewPager ，然后重写Viewpager的 onInterceptTouchEvent()的方法

代码：

    package cc.coach.bodyplus.widget;

    import android.content.Context;
    import android.support.v4.view.ViewPager;
    import android.util.AttributeSet;
    import android.view.MotionEvent;

    /** * Created by Bodyplus on 2016/4/18. * <p/> * <p/> * 解决 photoview 与viewpager 组合时 图片缩放的错误 ；异常：.IllegalArgumentException: pointerIndex out of range */
    public class BigPhotoViewPager extends ViewPager {


        public BigPhotoViewPager(Context context) {
            super(context);
        }

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

        @Override
        public boolean onInterceptTouchEvent(MotionEvent ev) {
            try {
                return super.onInterceptTouchEvent(ev);
            } catch (IllegalArgumentException e) {
                e.printStackTrace();
            } catch (ArrayIndexOutOfBoundsException e) {
                e.printStackTrace();
            }
            return false;
        }

    }
