原理和代码比较简单，就不再多说原理。但使用场景较多，特此记录，代码如下：

public class NoScrollViewPager extends ViewPager {
     private boolean noScroll = true;
     public NoScrollViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
     public NoScrollViewPager(Context context) {
        super(context);
    }
     public void setNoScroll(boolean noScroll) {
        this.noScroll = noScroll;
    }
     @Override
    public void scrollTo(int x, int y) {
        super.scrollTo(x, y);
    }
    //返回false表示不消费事件
    @Override
    public boolean onTouchEvent(MotionEvent arg0) {
        if (noScroll)
            return false;
        else
            return super.onTouchEvent(arg0);
    }
    //返回false表示不拦截事件
    @Override
    public boolean onInterceptTouchEvent(MotionEvent arg0) {
        if (noScroll)
            return false;
        else
            return super.onInterceptTouchEvent(arg0);
    }
     @Override
    public void setCurrentItem(int item, boolean smoothScroll) {
        super.setCurrentItem(item, smoothScroll);
    }
     @Override
    public void setCurrentItem(int item) {
        //false 表示没有切换动画
        super.setCurrentItem(item,false);
    }
}
