Android仿開心消消樂大樹星星無限循環(huán)效果
更新時(shí)間：2016年07月26日 11:12:25 作者：liudao7994
這篇文章主要為大家詳細(xì)介紹了Android仿開心消消樂大樹星星無限循環(huán)效果，自定義view實(shí)現(xiàn)效果，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下
啥都不說先上效果圖，這個(gè)是我項(xiàng)目里的效果：
下面的是我抽取出來的 demo 適配啥的我基本上都做好了沒做其他的
ok 下面 說一下思路把
首先 說一下原理 我是使用bitmap 創(chuàng)建兩張圖 一開始的時(shí)候 一張?jiān)谙旅嬗洖?號(hào) 一張?jiān)谏厦?記為2號(hào)
當(dāng)手指向下滑動(dòng)時(shí) 判斷 1號(hào) 的起點(diǎn)位置 是否完全超出屏幕 如果超出屏幕的話 那么將2號(hào)變?yōu)橄旅?1號(hào)變?yōu)樯厦?(移動(dòng)1號(hào)的Y坐標(biāo)) 大體思路 是這樣. 里面還有許多判斷
比如 是否能向下滑動(dòng) 起點(diǎn)位置, 星星的判定 哎呀 好煩 說的東西太多啦 來張我的草稿紙 哈哈 話說我草稿都寫了好幾頁
先上代碼：
