cocos2dx scrollview将选中项移动到视图中间位置

//Inner的最小Y值 float minY = m_listIndex->getContentSize().height - m_listIndex->getInnerContainerSize().height; //Inner超出部分的高度 float h = -minY; //选中项对应view的位置 //float viewY = (btn->getPositionY()) + m_listIndex->getInnerContainerPosition().y; //inner的目标位置即选中项移动到view中间的位置 float innerTargetY = m_listIndex->getContentSize().height / 2 - btn->getPositionY(); if (innerTargetY > 0) innerTargetY = 0; if (innerTargetY < minY) innerTargetY = minY; //m_listIndex->getInnerContainer()->setPositionY(innerTargetY); float percent = 100 - abs(innerTargetY) / h * 100; m_listIndex->scrollToPercentVertical(percent, PublicData::s_fIndexDuration, true);
