做項目要求某種情況下ViewPager不能滑動
百度后發現重寫ViewPager，覆蓋ViewPager的onInterceptTouchEvent(MotionEvent arg0)方法和onTouchEvent(MotionEvent arg0)方法，這兩個方法的返回值都是boolean類型的，只需要將返回值改為false，那么ViewPager就不會消耗掉手指滑動的事件了
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);}}
