　　　　常用工具类总结    http://blog.csdn.net/krislight/article/details/11354119

 

一、 UML类图复习：

       UML类图中有些标记很容易混淆，这里先复习下，请大家看下面这幅图：

    注：这幅图来自《大话设计模式》这本书中的插图。

二、应用框架：

       A、基本概念

       抽象（抽出共同之现象）——在同领域的程序中，常含有许多类别，这些类别有其共同点，我们将类别之共同结构抽离出来，称为抽象类别。其抽象之步骤是： 1、观察几个相似的类别；2、分辨它们的异同点；3、把它们的共同点抽离出来。

       衍生（与众不同之现象）——基于通用结构里的抽象类别，添加些特殊功能（扩展），使之成为具体类别，再诞生对象。

       所以抽象类别的存在目的，是要用其衍生子类别，而不是由它本身来诞生对象。由于抽象类别本身不诞生对象，所以有些方法并不完整。反之，类别之内的方法，皆是完整的，而且要用来诞生对象，就称它为具体类别。所谓不完整就是方法的方法体从缺，只有方法的描述。

       B、打造自己的专属应用框架之类图：

        C、 打造自己的专属应用框架之编码实现：

    BaseApplication类源码如下：

package com.lbt.hairdesigner;

import java.util.ArrayList;

import android.app.Activity;
import android.app.Application;

/**
 * 功能描述：用于存放全局变量和公用的资源等
 * @author android_ls
 */
public class BaseApplication extends Application {

    /**
     * Activity集合
     */
    private static ArrayList<BaseActivity> activitys = new ArrayList<BaseActivity>();

    @Override
    public void onCreate() {

    }

    /**
     * 添加Activity到ArrayList<Activity>管理集合
     * @param activity
     */
    public void addActivity(BaseActivity activity) {
        String className = activity.getClass().getName();
        for (Activity at : activitys) {
            if (className.equals(at.getClass().getName())) {
                activitys.remove(at);
                break;
            }
        }
        activitys.add(activity);
    }

    /**
     * 退出应用程序的时候，手动调用
     */
    @Override
    public void onTerminate() {
        for (BaseActivity activity : activitys) {

}
