啥都不说先上效果图把… 这个是最终的效果![这里写图片描述]
下面的是我抽取出来的 demo 适配啥的我基本上都做好了
没做其他的
=============================================================
分割线
==================================================================
ok 下面 说一下思路把
首先 说一下原理 我是使用bitmap 创建两张图 一开始的时候 一张在下面记为1号 一张在上面 记为2号
当手指向下滑动时 判断 1号 的起点位置 是否完全超出屏幕 如果超出屏幕的话 那么将2号变为下面 1号变为上面 (移动1号的Y坐标) 大体思路 是这样. 里面还有许多判断
比如 是否能向下滑动 起点位置, 星星的判定 哎呀 说的东西太多啦 来张我的草稿纸 哈哈 话说我草稿都写了好几页
下班了 我先上代码
