做项目要求某种情况下ViewPager不能滑动
百度后发现重写ViewPager，覆盖ViewPager的onInterceptTouchEvent(MotionEvent arg0)方法和onTouchEvent(MotionEvent arg0)方法，这两个方法的返回值都是boolean类型的，只需要将返回值改为false，那么ViewPager就不会消耗掉手指滑动的事件了
public class NoScrollViewPager extends ViewPager {private boolean noScroll = false;public NoScrollViewPager(Context context, AttributeSet attrs) {super(context, attrs);}public NoScrollViewPager(Context context) {super(context);}public void setNoScroll(boolean noScroll) {this.noScroll = noScroll;}@Overridepublic void scrollTo(int x, int y) {super.scrollTo(x, y);}@Overridepublic boolean onTouchEvent(MotionEvent arg0) {if (noScroll)return false;elsereturn super.onTouchEvent(arg0);}@Overridepublic boolean onInterceptTouchEvent(MotionEvent arg0) {if (noScroll)return false;elsereturn super.onInterceptTouchEvent(arg0);}@Overridepublic void setCurrentItem(int item, boolean smoothScroll) {super.setCurrentItem(item, smoothScroll);}@Overridepublic void setCurrentItem(int item) {super.setCurrentItem(item);}}
...)
