Android拼圖游戲開發全紀錄5

今天我們終於可以把這個項目給結束掉啦，有了前幾天的准備，相信最後一天還是比較輕松的，國際慣例：

最後要完成的就是我們的主要功能--拼圖界面。<喎?/kf/ware/vc/" target="_blank" class="keylink">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"brush:java;">package com.xys.xpuzzle.activity;

自認為注釋、代碼風格還是不錯的，希望大家喜歡。

PS：需要源代碼的朋友請留言，其實根據這個思路自己去實現下，對自己是有很大提高的，如果能優化我的代碼，那就更好了，可以一起學習交流下。
