【移動應用開發(fā)技術(shù)】Android應用實踐之數(shù)獨游戲開發(fā)的示例分析
這篇文章主要介紹了Android應用實踐之數(shù)獨游戲開發(fā)的示例分析，具有一定借鑒價值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓在下帶著大家一起了解一下。數(shù)獨游戲是一種源自18世紀末的瑞士的游戲，后在美國發(fā)展、并在日本得以發(fā)揚光大的數(shù)學智力拼圖游戲。拼圖是九宮格（即3格寬×3格高）的正方形狀，每一格又細分為一個九宮格。在每一個小九宮格中，分別填上1至9的數(shù)字，讓整個大九宮格每一列、每一行的數(shù)字都不重復。數(shù)獨的玩法邏輯簡單，數(shù)字排列方式千變?nèi)f化。不少教育者認為數(shù)獨是鍛煉腦筋的好方法，上外語閱讀課的時候外教老師就很喜歡帶我們玩這個，樂此不疲，老外的教學方式還是很受歡迎的。但是每次玩這個游戲的時候都要發(fā)一張數(shù)獨游戲卡，嫌麻煩，就想著寫一個demo放自己手機上，想想那個時候真是好奇心爆棚，碰上很火爆的小游戲都想整一個DIY的Demo，叨叨夠了，哈哈，上源碼。一、界面布局1.主界面<?xml
