Google了一下,终于搞清了touch screen下的几种操作模式(对应的是事件). 对于一个view, 常用的操作有点击(click)和长按(long press)二种.实际上,这些操作类型是Android内部在onTouchEvent(MotionEvent event)里对用户的动作做了一定的分析,从而通知应用程序是发生了点击还是长按等事件. 有时,我们需要的并不仅限于这两种操作.我们可以借助GestureDetector来分析出更细致的操作类型.基本的过程就是创建一个myGestur…

onFling will get executed when a user makes a "fling" motion, and said motion has a velocity with it to determine the type of fling it was. However, if a user simply touches the device and moves slowly across the screen, that would not be consid…

问题解决-优化listView卡顿和怎样禁用ListView的fling 前戏非常长,转载请保留出处:http://blog.csdn.net/u012123160/article/details/47720257 问题产生 这算是刚到实习公司接触到的第一个任务.公司某一产品中某个界面的listView高速滑动会有卡顿的现象发生,我的任务就是解决它. 产生原因分析 我一開始的想法比較简单.可能是listview的优化没有做到位,比如convertView的复用.viewHolder的使用等等基础…

Scroller主要用于平滑滚动,主要使用的滚动方法有:startScroll.fling. startScroll(int startX, int startY, int dx, int dy, int duration): 指定起点(startX,startY),从起点平滑变化(dx,dy),耗时duration,通常用于:知道起点与需要改变的距离的平滑滚动等. fling(int startX, int startY, int velocityX, int velocityY,      …

题意巨难懂.简言之,就是球互相碰撞时,主动碰撞的球将会停止,另一个球将沿着碰撞方向继续移动,不断碰撞.但是无法弹射紧挨着的球,但是若a弹射b,bc相邻,这种情况b可以弹射c. #include <iostream> #include <cstdio> #include <cstring> #include <algorithm> using namespace std; #define MAXN 10 typedef struct { int x, y; c…

自定义控件 Android系统提供了一系列UI相关的类来帮助我们构造app的界面,以及完成交互的处理. 一般的,所有可以在窗口中被展示的UI对象类型,最终都是继承自View的类,这包括展示最终内容的非布局View子类和继承自ViewGroup的布局类. 其它的诸如Scroller.GestureDetector等android.view包下的辅助类简化了有关视图操作和交互处理. 无论如何,自己的app中总会遇到内建的类型无法满足要求的场景,这时就必须实现自己的UI组件了. 自定义控件的方式 根据…
