Android ScrollView嵌套横向滑动控件时冲突问题

public void setOnScollChangedListener(OnScollChangedListener onScollChangedListener) {  this.onScollChangedListener = onScollChangedListener;}@Overrideprotected void onScrollChanged(int x, int y, int oldx, int oldy) {  super.onScrollChanged(x, y, oldx, oldy);  if (onScollChangedListener != null) {    onScollChangedListener.onScrollChanged(this, x, y, oldx, oldy);  }}public interface OnScollChangedListener {  void onScrollChanged(ObservableScrollView scrollView, int x, int y, int oldx, int oldy);}@Overridepublic boolean onInterceptTouchEvent(MotionEvent ev) {  switch (ev.getAction()) {  case MotionEvent.ACTION_DOWN:    xDistance = yDistance = 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);    xLast = curX;    yLast = curY;    /**     * X轴滑动距离大于Y轴滑动距离，也就是用户横向滑动时，返回false，ScrollView不处理这次事件，     * 让子控件中的TouchEvent去处理，所以横向滑动的事件交由子控件处理， ScrollView只处理纵向滑动事件     */    if (xDistance > yDistance) {      return false;    }  }  return super.onInterceptTouchEvent(ev);}}
