* 而刷新/获取其实更多的时候可以理解成是ListView的层面, 这在于讨论到底是一个"可刷新的Activity"
* 还是一个拥有"可刷新的ListView"的Activity, 如果改成后者, 则只要在父类拥有一个实现了可刷新接口的ListView即可,
* 而无需强制要求子类去直接实现某些方法.
* 2. 父类过于专制, 比如getLayoutId()等抽象方法的存在只是为了在父类进行setContentView, 而此类方法可以下放到子类去自行实现,
* 诸如此类的, 应该下放给子类更自由的空间. 理想状态为不使用抽象类.
* 3. 随着功能扩展, 需要将几个不同的ListActivity子类重复的部分重新抽象到父类来, 已减少代码重复.
* 4. TwitterList和UserList代码存在重复现象, 可抽象.
* 5. TwitterList目前过于依赖Cursor类型的List, 而没有Array类型的抽象类.

* 数据的连贯性, 超出部分则视为垃圾数据, 不再允许读取, 也不保证其是前后连续的.<br />
* <br />
* 因为用户可能中途长时间停止使用本客户端,而换其他客户端(如网页), <br />
* 如果保证本地所有数据的连贯性, 那么就必须自动去下载所有本地缺失的中间数据,<br />
* 而这些数据极有可能是用户通过其他客户端阅读过的无用信息, 浪费了用户流量.<br />
* <br />
* 即认为相对于旧信息而言, 新信息对于用户更为价值, 所以只会新信息进行维护, <br />
* 而旧信息一律视为无用的, 如用户需要查看超过MAX_ROW_NUM的旧数据, 可主动点击, <br />
* 从而请求服务器. 本地只缓存最有价值的MAX条最新信息.<br />
* <br />
* 本地数据库中前MAX_ROW_NUM条的数据模拟一个定长列队, 即在尾部插入N条消息, 就会使得头部<br />
* 的N条消息被标记为垃圾数据(但并不立即收回),只有在认为数据库数据过多时,<br />
* 可手动调用 <code>StatusDatabase.gc(int type)</code> 方法进行垃圾清理.<br />
