又一个Android UI设计实例：蘑菇街UI仿制品源码，这个界面中包括了菜单、图片切换的幻灯片、用户登录和注册按钮示例等，看上去十分漂亮的一个Android手机界面UI，通过仿写这个UI，你可以对Android界面的设计的基础知识技巧有一个更深的理解，进一步熟悉各种操作技巧，本例视图效果如截图所示。

包括以下功能： 1.支付（支付宝，微信，百度钱包，网银）  2.首页 3.热卖 4.商品大全  5.购物车  6.我的  7.商品列表  8.商品详情  9.注册/登录  10.收货地址  11.我的订单  12.我的收藏

通过对本实例源码的深入学习研究，了解和掌握一个完整的安卓APP是如何制作出来的，源码内附详细注释。

Google Android SDK开发范例大全(完整版)虽然半行代码都没有写，但向导却帮忙写好了程序进入点、布局配置、字符 串常数、应 用程序访问权限等， 除了可作为程序模板之外， 也是 Android 手机程 序的最佳学习范例。让 我们回过头来看看刚才 Android 项目建立向导帮忙做了哪些工作， 以此来 了解 Android 应 用程序的生命周期及其文件组成方式； 首先， 展开 (package helloworld.irdc.eracom.com.cn import android.app.Activity import android.os.Bundle public class HelloWorld extends Activity { * Called when the activity is first created. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState) setContentView(R.layout.main) } } )

对调制解调器的经典编程,具有较好的研究价值！()

演示Android自动同步机制的测试例子，换种说法也就是说自动同步就是几个线程自动的过一段时间执行一次看看服务器端有没有更新而已。也就是每过一段时间执行一次线程。
