Patterns
Singleton
Classes that implement singleton
- App
- HttpManager
- InternalData
- NotificationReceiver
Command
All classes in managers/commands
UnfriendCommand, CancelEventCommand and RemoveEventCommand are implemented Command, because ConfirmDialog.java will execute a command so we will pass these function in type of Command
These are commands for making interaction with the server.
Mediator
- Notifier
- DateTimeHolder
When user want to select date and time from picker dialog, the ui must be updated after date
and time are selected. So I created DateTimeHolder for holding tvDate,tvTime and setting
date and time logics (listener).
Adapter
classes in ui/adapters
These adapters are accept list of any type of object (for example, List<Friend>)
and convert it to custom view
Observer
most activity and fragment are observer, which updates when a response notify it.
Facade
- LoadService - hides the complexity of making connection to server logic.
FlyWeight
- InternalData - reuse icons in many activity
Principles
Open-Closed
Friend is an extension of User, User is closed for modification.
Don't repeat yourself
use <merge> and <include> in layout to reuse components.
item_partial_event.xml included in item_event_explore.xml
friend_list_include.xml included in fragment_friends.xml
Single Responsibility
- joinpa/models
- EventManager
- PlaceManager
Information expert
- EventManager
- PlaceManager
- HttpManager
- App
Low coupling, High cohesion
- joinpa/util
- DateUtil for formatting date, reducing the need of activity to include logic for that.
- ProgressDialogUtil for showing load dialog and hiding without coupling in activity or fragments
