Command

A Java utility library for handling asynchronize events.

Command utility is a wrapper to Handler of Android SDK. Providing a relatively clean and easy access to Handler API using chaining call.

There is two part using Command. One is Command, the other is Resolver.

Command is used to issue specific event with some arguments. And Resolver is created to handle the raised events.

Here is a Resolver declaration code

  public static final int SCROLL_LIST_FOR_DISTANCE_IN_ANY_MILLIS = 10;
  
  @Resolver(id = SCROLL_LIST_FOR_DISTANCE_IN_ANY_MILLIS)
  public static void SCROLL_LIST_FOR_DISTANCE_IN_ANY_MILLIS(ListView v, int distance, int duration) {
    v.smoothScrollBy(distance, duration);
  }

We create a resolver function and assign an id of 10. When the SCROLL_LIST_FOR_DISTANCE_IN_ANY_MILLIS event is fired, function is invoked in asynchronized manner. The resolver scrolls a view to the distance.

In addition, you will need to register your class to Command. You can add the following code to everywhere in your class. To the previous example, I put the Resolver in class named U.

  static {
    // Register Async Operation
    com.dummi.common.command.Command.register(U.class);
  }

Then, we will be able to fire the event.

  Command.invoke(SCROLL_LIST_FOR_DISTANCE_IN_ANY_MILLIS) // Fire SCROLL_LIST_FOR_DISTANCE_IN_ANY_MILLIS
         .args(parent, viewY, 300)                       // Pass arguments
         .only()                                         // Remove other Fire request to the same Event
         .sendDelayed(100);                              // Fire the event after 100ms
