弹出式菜单（下拉菜单）实现——PopupMenu

PopupMenu代表弹出式菜单,它会在指定组件上弹出PopupMenu,默认情况下,PopupMenu会显示在该组件的下方或上方.PopupMenu可增加多个菜单项,并可为菜单项增加子菜单. 使用PopupMenu创建菜单的步骤非常简单,只要如下步骤即可. 调用new PopupMenu(Context context,View anchor)创建下拉菜单,anchor代表要激发该弹出菜单的组件. 调用MenuInflater的inflate()方法将菜单资源填充到PopupMenu中. 调用

leetcode第一刷_Set Matrix Zeroes

这个题乍一看很简单,实际上还挺有技巧的.我最开始的想法是找一个特殊值标记,遇到一个0,把他所对应的行列中非零的元素标记成这个特殊值,0值保持不变,然后再从头遍历一次,碰到特殊值就转化成0. 问题是这个特殊值怎么确定,题目中没有把取值范围给出,我怀着侥幸的心理用了最大和最小的int,都被揪了出来..如果找一个不存在于数组中的值,这个复杂度太高了. 有没有其他更好的方法呢?当然有.这个思想很巧妙,最后的结果是把所有0所在的行列都化成0,换句话说,化成0这个事情只要标记出是哪一行以及哪一列就可以了,能

C++ Primer(第五版)学习笔记_6_标准模板库_set集合容器 Set集合容器实现了红黑树(Red-BlackTree)的平衡二叉检索树的数据结构,在插入元素时,它会自动调整二叉树的排序,把该元素放到适当的位置. (1)确保每个子树根节点的键值大于左子树所有节点的键值,而小于右子树所有节点的键值: (2)另外,还得确保根节点左子树的高度与右子树的高度相等.这样,二叉树的高度最小,从而检索速度最快. 平衡二叉检索树的检索使用中序遍历算法,检索效率高.默认情况下,将键值由小到大遍历. 对于s
