ScrollView种嵌套ViewPager

滑动看起来是不是很流畅

需要改写ScrollView

就是在触摸事件拦截器里面

判断，如果横着滑动的距离大于竖着滑动的距离，就返回false也就是不拦截当前事件，传递给下一层执行

public class ScrollViewExtend extends ScrollView{private float xDistance;private float yDistance;private float xLast;private float yLast;public ScrollViewExtend(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);// TODO Auto-generated constructor stub}public ScrollViewExtend(Context context, AttributeSet attrs) {super(context, attrs);// TODO Auto-generated constructor stub}public ScrollViewExtend(Context context) {super(context);// TODO Auto-generated constructor stub}@Overridepublic boolean onInterceptTouchEvent(MotionEvent ev) {switch (ev.getAction()) {case MotionEvent.ACTION_DOWN:xDistance = yDistance = 0.0f;xLast = ev.getX();yLast = ev.getY();break;case MotionEvent.ACTION_MOVE:final float curX = ev.getX();final float curY = ev.getY();xDistance += Math.abs(curX - xLast);yDistance += Math.abs(curY - yLast);if(xDistance > yDistance)return false;break;default:break;}return super.onInterceptTouchEvent(ev);}}
