1. 关于菜单

* 有三种：Options Menu, Contect Menu, Sub Menu

* Options Menu:

Activity::OnOptionsMenuCreated, OnOptionsMenuSelected

事件处理方式：

   OnOptionsMenuSelected

   直接访问Menu Item，绑定Listener.

* Context Menu

   OnXXXCreated/OnXXXSelected

 

2. Dialog

Activity::onCreateDialog, showDiaglog

 

3. Handler

 

DEV guide:

 

When a process is created for your application, its main thread is dedicated to running a message queue that takes care of managing the top-level application objects (activities, broadcast receivers, etc) and any windows they create. You can create your own threads, and communicate back with the main application thread through a Handler. This is done by calling the same post or sendMessage methods as before, but from your new thread. The given Runnable or Message will than be scheduled in the Handler's message queue and processed when appropriate

 

Q: 这个handler使用的queue与main thread中用的queue是相同还是不同？

 

4. 问题

Q： 如何引入android.jar的源代码到工程？

 

5. 几件今天要搞定的事：

* 注册google帐号

* 对应用进行签名并试验

* SVN公网访问帐号
