我遇到了生命遊戲的麻煩，我的幾代人都在經歷，但是它做得不正確。我有一個生成類，它持有遊戲的規則和世代的運動。一個RunActivity，它通過移動並將其發送到一個myView類，該類接收新的二維數組並將其「繪製」到屏幕上。 MyView有兩個setPoint方法，一個基於來自gen類的二維數組添加點到一個二維數組，另一個基於觸摸運動添加點。另外還有一個ontouchlistener，它增加了一個點的數組列表和一個主要活動獲取生活遊戲的設置。這是我最相關的代碼：生命的遊戲Android Java

的受阻代碼是另外一個版本我是想這並沒有工作，要麼但具有不同的影響。

我有這個代碼玩弄ssoooo太多，無法弄明白。再次感謝您的幫助
我在這裏看到很好的評論和問題，但是所有的代碼都會真正限制實際閱讀並提供答案的人數。你能縮小代碼的範圍嗎？ – rfornal 2014-12-07 03:07:17
謝謝，我縮短了它與更相關的內容。 – Matt 2014-12-07 03:22:13
在你的grow（）函數中，你沒有清除genb。如果您對編程/ Java/Android不熟悉，您可能希望首先將您的代碼作爲基本Java程序在Android之外工作，然後將其遷移到Android，以便您可以知道工作的起點。祝你好運。 – 2014-12-07 05:05:52
