Android应用的中滑动事件出现冲突如何解决

@Override  public boolean onInterceptTouchEvent(MotionEvent ev) {  boolean intercepted = false;  int x = (int) ev.getX();  int y = (int) ev.getY();  switch (ev.getAction()) {  case MotionEvent.ACTION_DOWN:  //down事件不拦截，否则无法传给子元素  intercepted = false;  if (!mScroller.isFinished()) {   mScroller.abortAnimation();   intercepted = true;  }  break;  case MotionEvent.ACTION_MOVE:  int deltaX = x - mLastXIntercept;  int deltaY = y - mLastYIntercept;  //水平滑动则拦截  if (Math.abs(deltaX) > Math.abs(deltaY) + 5) {   intercepted = true;  } else {   intercepted = false;  }  break;  case MotionEvent.ACTION_UP:  //不拦截，否则子元素无法收到  intercepted = false;  break;  }  //因为当ViewGroup中的子View可能消耗了down事件，在onTouchEvent无法获取，  // 无法对mLastX赋初值，所以在这里赋值一次  mLastX = x;  mLastY = y;  mLastYIntercept = y;  mLastXIntercept = x;  return intercepted;  }
