Android實現(xiàn)模擬時鐘

1、Android 實現(xiàn)模擬時鐘 （簡單 漂亮 ）、八 、-前言 前不久在網(wǎng)上看見 Android 實現(xiàn)的 模擬時鐘，感覺十分有意思，這里是地址： id=58324 可惜的是這種方式?jīng)]有秒表。筆者突然對其有了興趣，也想去實 現(xiàn)以下自己的模擬時鐘。折騰了一陣子總算是弄出來了現(xiàn)在將實現(xiàn)方式共享出來，大家一些交 流。不多說，先上效果圖：準(zhǔn)備工作首先我們應(yīng)該準(zhǔn)備相關(guān)的素材：時鐘 盤、時針、分針、秒針圖片 .時鐘盤：時針：分針： 秒針：源碼部分配置文件，比較簡單： <LinearLayout xmlns:android= xmlns:tools= android:layout_width=fill_p
