genetics's Introduction

Genetics

Genetics allows attributes to be used to describe how to inject resources, views and events into an object. Based on the resource ID provided, it can inject the appropriate Android View or Android resource. Or, it can automatically attach event handlers to View events.

Use [Splice] on fields and properties instead of FindViewById method calls.
Use [Splice] on fields and properties instead of GetString or GetDrawable method calls.
Use [SpliceEvent], or others like [SpliceClick], on methods instead of attaching delegates to events.

public class MyActivity : Activity
{
  [Splice(Resource.Id.username)]
  private EditText username;
  [Splice(Resource.Id.password)]
  private EditText password;
  [Splice(Resource.String.loginError)]
  private string loginErrorMessage;

  [SpliceClick(Resource.Id.login)]
  private void LoginClicked(object sender, EventArgs e)
  {
    // TODO: perform login...
  }

  protected override void OnCreate(Bundle savedInstanceState)
  {
    base.OnCreate(savedInstanceState);
    
    // load the view layout
    SetContentView(Resource.Layout.MyActivityLayout);
    // inject the views
    Geneticist.Splice(this);
    
    // TODO: use fields...
  }
  
  protected override void OnDestroy()
  {
    // dispose of events and resources
    Geneticist.Sever(this);

    base.OnDestroy();
  }
}
