应用背景俄罗斯方块是一款电视游戏机和掌上游戏机游戏，它由俄罗斯人阿列克谢 帕吉特诺发明，故得此名。俄罗斯方块的基本规则是移动、旋转和摆放游戏自动输出的各种方块，使之排列成完整的一行或多行并且消除得分。由于上手简单、老少皆宜，从而家喻户晓，风靡世界。关键技术本文件介绍了运用Java完成该游戏的代码编写并成功运行的技术。包括俄罗斯方块单机游戏和双人对战游戏，运行都成功。在整个过程中涉及到了Java基本知识的大部分内容，有利于Java爱好者的学习与借鉴。

应用背景是一种可以撰写跨平台应用软件的面向对象的程序设计语言Java。Java技术具有卓越的通用性、高效性、平台移植性和安全性，广泛应用于PC、数据中心、游戏控制台、科学超级计算机、移动电话和互联网，同时拥有全球最大的开发者专业社群。关键技术Java是由Sun Java（Java公司推出的面向对象程序设计语言以下简称语言）和Java平台的总称。由杰姆斯Gosling和同事们共同研发，并在1995年正式推出。Java最初被称为橡木，是1991年为消费类电子产品的嵌入式芯片而设计的。1995年更名为Java，并重新设计用于开发互联网应用程序。

先用一个TabHost将一个Activity分为左右两边，左边菜单点击后用上面一个ImageSwitcher下面一个Gallery显示图片，右边菜单点击后，先用GridView显示网格状的小图片，点击图片之后会跳转到另外一个界面，以全屏的方式显示图片。同时所有图片都支持点击大图显示，长按删除功能。
