原文:http://www.cnblogs.com/L-hq815/archive/2012/08/04/2622829.html 一台机器上可能不只有一个网卡,但每一个网卡只有一个 MAC 地址,而每一个网卡可能配置有多个 IP 地址;如平常的笔记本电脑中,就会有无线网卡和有线网卡(网线接口)两种;因此,如果要获得本机所有网卡的 IP 和 MAC 地址信息,则必须顺序获得每个网卡,再依次获取其信息等;在 windows sdk 中,用 IP_ADAPTER_INFO 结构体存储网卡信息,包括网卡名、网卡描述、网卡 MAC 地址、网卡 IP 等,该结构体的主要描述如下所示: typedef struct _IP_ADAPTER_INFO {    struct _IP_ADAPTER_INFO* Next; // 指向链表中下一个适配器信息的指针   DWORD ComboIndex; // 预留值    char AdapterName[MAX_ADAPTER_NAME_LENGTH + 4 ]; // 使用ANSI字符串表示的适配器名称    char Description[MAX_ADAPTER_DESCRIPTION_LENGTH + 4 ]; // 使用ANSI字符串表示的适配器描述   UINT AddressLength; // 适配器硬件地址以字节计算的长度

问题 Ok, I have been searching thick and thin, and I am having some issues implementing a BaseAdapter. I have been able to implement a Simple Cursor Adapter http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List7.html as per the example above. There is a pretty good BaseAdapter example here : List14 google example I am wanting to create my own List Adapter using BaseAdapter to show a listView, with multiple items from a Database. I know this can be done

How to implement an endless gallery in Android?

我们两清 提交于 2019-11-26 18:09:42
问题 I am using a gallery layout in my application. It is working when the user moves the pictures in the gallery from left to right (it is infinite that means elements are repeated again). But when the user moves from right to left and reaches the first element, it doesn't. After then no elements are coming. But I want to repeat elements from this side also. Can you give me some suggestions? Gallery g = (Gallery) findViewById(R.id.gallery); g.setAdapter(new ImageAdapter(this)); g.setFocusable

What's the role of adapters in Android?

不问归期 提交于 2019-11-26 17:53:52
问题 I want to know when , where and how adapters are used in the context of Android. The information from Android's developer documentation was insufficient for me and I'd like to get a more detailed analysis. 回答1: Well adapters in Android are basically a bridge between the UI components and the data source that fill data into the UI Component For example, Lists (UI Component) get populated by using a list adapter, from a data source array. 回答2: Let’s assume you want to display a list in your

iterator adapter to iterate just the values in a map?

泪湿孤枕 提交于 2019-11-26 17:47:09
问题 I'm just getting back into C++ after a couple of years of doing a lot of C#, and recently Objective C. One thing I've done before is to roll my own iterator adapter for std::map that will deref to just the value part, rather than the key-value pair. This is quite a common and natural thing to do. C# provides this facility with its Keys and Values properties of its Dictionary class. Objective-C's NSDictionary, similarly, has allKeys and allValues. Since I've been "away", Boost has acquired the

结构型设计模式——适配器模式(Go)

微笑、不失礼 提交于 2019-11-26 16:51:22
适配器模式:   适配器模式是用于当别人提供的对象或接口中的方法或者其它属性啥的和我们的重复了,或者看的不顺眼。名字太长了记不住,而将其包装到一个对象中,然后通过你感觉自己舒服的方式或者方法名字去间接的调用它。一个简单的例子就是三角插座,我没有三角口,用一个转接器呗。 对象适配器:   将那个你看的不顺眼的对象的引用存在你的包装类对象内 package mainimport "fmt"type Target interface { request()}type Adaptee struct {}func(it *Adaptee)specificrequeset(){ fmt.Println("asdf")}type Adapter struct { adaptee *Adaptee}func(it *Adapter)setAdaptee(adaptee *Adaptee){ it.adaptee = adaptee}func(it *Adapter)request(){ it.adaptee.specificrequeset()}func main(){ target := new(Adapter) adaptee := new(Adaptee) target.setAdaptee(adaptee) target.request()} 类适配器: 通过同时继承这两个类

适配器模式(Adapter)

守給你的承諾、 提交于 2019-11-26 16:39:06
前言:适配器就是一种适配中间件,它存在于不匹配的二者之间,用于连接二者,将不匹配变得匹配,简单点理解就是平常所见的转接头,转换器之类的存在。 概念:适配器模式的种类:1.类适配器(通过继承来实现适配器功能)、2.对象适配器(通过组合来实现适配器功能)、3.接口适配器(通过抽象类来实现适配)。 一:类适配器 :通过继承来实现适配器功能 生活场景:美国的插头是三角,中国的插头是两角,如 果让二角变三角 或者三角变两角呢?数据转换线就是适配器 代码实现: AmericaPower.java(美国插头接口),APower.java(实现类),ChinaPower.java(中国插头接口),CPower.java(中国插头实现类) public interface AmericaPower { public void threeStep(); } public class APower implements AmericaPower { @Override public void threeStep() { System.out.println("我是三角的电源"); } } public interface ChinaPower { public void twoStep(); } public class CPower extends APower implements

Difference between Bridge pattern and Adapter pattern

不羁的心 提交于 2019-11-26 15:21:33
问题 What is the difference between the Bridge and Adapter patterns? 回答1: "Adapter makes things work after they're designed; Bridge makes them work before they are. [GoF, p219]" Effectively, the Adapter pattern is useful when you have existing code, be it third party, or in-house, but out of your control, or otherwise not changeable to quite meet the interface you need it to. For instance, we have a SuperWeaponsArray which can control a fine array of doomsday devices. public class
