Injection

Simple Injection has support for views and methods injection. The injection has executed when the method inject() from Simple Activities is called.

• View Injection

	@InjectView(id=R.id.txt1)
	TextView txt1;

• Method Injection

	@InjectMethod(id=R.id.btn1)
	public void onBtnClick(View v){
		txt1.setText("Mensaje.....");
	}

	@InjectMethod(id=R.id.btn1,method="OnLongClickListener")
	public boolean onBtnLongClick(View v){
		txt1.setText("Long Message.....");
		return true;
	}
	

• Sample Class

public class MainActivity extends SimpleActivity {

	@InjectView(id=R.id.txt1)
	TextView txt1;

	@InjectMethod(id=R.id.btn1)
	public void onBtnClick(View v){
		txt1.setText("Mensaje.....");
	}

	@InjectMethod(id=R.id.btn1,method="OnLongClickListener")
	public boolean onBtnLClick(View v){
		txt1.setText("Long Mensaje.....");
		return true;
	}
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		inject();
	}

	

}

MV*

Simple Model-View-* provides functionalities to separate in the application the data layer, the logic and the UI's. this facilitates the process of application development and its maintenance.

• Data Layer: The data layer is composed by Models and Collections. One Model has many fields. One Collection has many Model instances.

Models and Collections allow assign callbacks (Delegates) when an item is added, modified or removed.

Let's see the sample:

class test {
    @Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		Collection collection = new Collection();
		collection.on("add", new CollectionDelegate() {
			
			@Override
			public void event(Model item) {
				System.out.println("added "+item);
			}
		});
		collection.on("edit", new CollectionDelegate() {
			
			@Override
			public void event(Model item) {
				System.out.println("item modified: "+item);
			}
		});
		
		Model m = new Model(collection);
		m.addField("newKey", "newValue");
		m.addField("anotherKey", "anotherValue");
    }
}

The output of las sample is:

added {}
item modified: {newKey=newValue}
item modified: {newKey=newValue, anotherKey=anotherValue}
