新手菜鸟求助，关于Adapter

大哥们：
          小弟是个新手，现在想定义一个Adapter，把数据显示在listView中。不知道代码怎么写……
          模拟数据如下：
private Product[] products={
                        new Product(1,"三星 GT-S5830", 1, R.drawable.p1,
                                        1630, "网络类型:WCDMA(3G) 操作系统:ANDROID "),
                        new Product(2,"HTC A510e", 1, R.drawable.p2,
                                                        1514, "网络类型:WCDMA(3G) 操作系统:ANDROID ")        ,        
                        new Product(3,"三星 I9100", 1, R.drawable.p3,
                                        3266, "网络类型:WCDMA(3G) 操作系统:ANDROID "),
                        new Product(4,"中兴 U880（TD版）", 1,
                                        R.drawable.p4, 989,
                                                        "网络类型:TD-SCDMA(3G) 操作系统:ANDROID  ")}；
