Coming soon

Getting started

Single Activity

MainActivity.java:

public class MainActivity extends SingleActivity {

  @Override
  protected Navigator createNavigator() {
    return Navigator.withRoot(new HomeScreen()).build();
  }

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
  }

}

activity_main.xml:

<com.wealthfront.magellan.ScreenContainer
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/magellan_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    /> 

Minimal Screen implementation

Screen example HomeScreen.java:

public class HomeScreen extends Screen<HomeView> {
  @Override
  protected HomeView createView(Context context) {
    return new HomeView(context);
  }
}

Associated View HomeView.java:

public class HomeView extends BaseScreenView<HomeScreen> {
  public HomeView(Context context) {
    super(context);
    inflate(context, R.layout.home, this);
  }
}
