首先给软件取名为HappyIdiom,在开始编码之前，需要先对程序进行需求分析，想一想HappyIdiom中应该具备哪些功能。将这些功能全部整理出来之后，我们才好动手一一实现。这里我认为HappyIdiom中至少应该具备以下功能：
1.成语分类学习：你可以根据自己喜欢的分类（动物类、人物类、季节类、自然类、数字类、语言类、其他类）来进行学习。
2.乐猜成语：学习之余玩玩猜成语游戏，寓教于乐。
3.成语收藏：当用户遇到自己想要保存的成语，点击保存按钮，即保存到收藏页面以方便用户再次查看，对已经掌握的成语，用户可以从收藏夹中删除。
4.成语查询：支持首字母查询，如一心一意可输入：yxyy。
虽然看上去只有四个主要的功能点，但如果想要全部实现这些功能却用到UI/网络、数据存储等技术，因此还是非常考验综合能力的。
分析完了需求之后，接下来就要进行技术的可行性分析了。首先要考虑的一个问题就是，我们如何才能得到所有的成语数据，以及如何才能获取每个成语的读音，解释，近义词反义词等信息。聚合网给我们提供了免费的聚合数据，网址如下：https://www.juhe.cn/docs/api/id/157 也可以从网上查找。
获取了数据库版本之后，就开始创建HappyIdiom这个项目了，在Eclipse中新建一个Android项目，项目名叫做HappyIdiom，包名叫做cn.edu.bztc.HappyIdiom，使用的是4.2的API，如图所示：
创建好了之后，然后再创建几个包，如图所示：
在res目录下新建raw目录，将idioms.db数据库复制到此目录下。这是因为raw目录的东西，android会原封不动的拷贝到程序中，而不会转换为二进制文件。在db包下新建一个DBOpenHelper类，代码如下：

上面的代码功能主要是使用输出流将idioms.db复制到手机中默认存放数据库的位置。
接下来在test包下，新建DBOpenHelperTest继承AndoidTestCase。代码如下：

然后在entity包下新建一个Animal类，代码如下：

可以看到，AnimalDao是一个单例类，我们将它的构造方法私有化，并提供了一个getInstance()方法来获取AnimalDao的实例，这样就可以保证全局范围内只会有一个AnimalDao的实例。接下来我们在AnimalDao中提供了一个方法getAllAnimals()该方法用来获取所有的动物类成语。编写单元测试类AnimalDaoTest继承AndroidTestCase，代码如下：

布局文件中的内容比较简单，主要是拖了一个TabHost空间到界面上，如图所示：
然后再res的values目录的strings.xml文件中定义所需的字符串。代码如下：

Category类中只有两个字段，name表示类的名字，imageId表示类别对应图片的资源id。
在layout下新建activity_study.xml文件，主要添加了一个ListView控件，代码如下：

</span><span class="tag" style="box-sizing: border-box; color: rgb(0, 0, 136);"></RelativeLayout></span>
然后需要为ListView的子项指定一个我们自定义的布局，在layout目录下新建category_item.xml，代码如下：
<span class="pun" style="box-sizing: border-box; color: rgb(102, 102, 0);"><?</span><span class="pln" style="box-sizing: border-box; color: rgb(0, 0, 0);">xml version</span><span class="pun" style="box-sizing: border-box; color: rgb(102, 102, 0);">=</span><span class="str" style="box-sizing: border-box; color: rgb(0, 136, 0);">"1.0"</span><span class="pln" style="box-sizing: border-box; color: rgb(0, 0, 0);"> encoding</span><span class="pun" style="box-sizing: border-box; color: rgb(102, 102, 0);">=</span><span class="str" style="box-sizing: border-box; color: rgb(0, 136, 0);">"utf-8"</span><span class="pun" style="box-sizing: border-box; color: rgb(102, 102, 0);">?></span><span class="pln" style="box-sizing: border-box; color: rgb(0, 0, 0);">

在这个布局中，我们定义了一个ImageView用于显示类别图片，又定义了一个TextView用于显示类别的名称。接下来需要在应用包下创建adapter包，再改包下创建一个自定义的适配器，这个适配器继承自ArrayAdapter，并将泛型指定为Category类，新建类CategoryAdapter，代码如下所示：

CategoryAdapter重写了父类的一组构造函数，用于将上下文、ListView子项布局id和数据都传递进来。另外有重写了getView()方法，这个方法每个子项被滚动到屏幕内的时候调用。在getView方法中，首先通过getItem()方法得到当前项的Category实例，然后使用L ayouInflater来为这个字项加载我们传入的布局，接着调用View的findViewById()方法分别获取ImageView和TextView的实例，并分别调用它们的setImageResource()和SetText()方法来设置爱显示的图片和文字，最后将布局返回，这样我们自定义的适配器就完成了，下面在activity包下新建StudyActivity继承自Activity，代码如下所示：

这时界面载入的过程有些生硬，下面为界面增加淡入淡出的动画效果，在res目录下新建anim目录，在下面创建anim_listview.xml文件，代码如下：

设置了一个Alpa动画，从无到有的过程，创建anim_layout_listview.xml文件，代码如下：

在layout下新建activity_animal.xml文件，主要添加了ListView控件，代码如下：

然后需要为ListView的子项指定一个我们自定义的布局，在layout目录下新建animal_item.xml,代码如下所示：
