private MotionEvent transformEvent(MotionEvent e, int headerPosition) {
  if (headerPosition == MATCHED_STICKIED_HEADER) {
    return e;
  }
  long downTime = e.getDownTime();
  long eventTime = e.getEventTime();
  int action = e.getAction();
  int pointerCount = e.getPointerCount();
  int[] pointerIds = getPointerIds(e);
  MotionEvent.PointerCoords[] pointerCoords = getPointerCoords(e);
  int metaState = e.getMetaState();
  float xPrecision = e.getXPrecision();
  float yPrecision = e.getYPrecision();
  int deviceId = e.getDeviceId();
  int edgeFlags = e.getEdgeFlags();
  int source = e.getSource();
  int flags = e.getFlags();
  View headerHolder = getChildAt(headerPosition);
  for (int i = 0; i < pointerCount;i++) {
    pointerCoords[i].y -= headerHolder.getTop();
  }
  MotionEvent n = MotionEvent.obtain(downTime, eventTime, action,
      pointerCount, pointerIds, pointerCoords, metaState, xPrecision,
      yPrecision, deviceId, edgeFlags, source, flags);
  return n;
