indirect-injector

The indirect-injector simplify confusion of communication between activity and fragment, and dependencies.

Problem

Yes. Here's the answer.

Setup

Gradle:

repositories {
    mavenCentral()
    maven { url 'https://raw.githubusercontent.com/sys1yagi/indirect-injector/master/repository' }
}

dependencies {
    compile 'com.sys1yagi:indirect-injector:0.0.2'
}

Usage

TODO:description

Activity

public class MainActivity extends FragmentActivity {

  ItemListFragment.Callbacks mCallback = new ItemListFragment.Callbacks() {
    @Override
    public void onItemSelected(int id) {
		//Called from fragment.
    }
  }

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    IndirectInjector.addDependency(this, mCallback);
    
    //initialize
    //...
  }

Fragment

TODO:description

public class ItemListFragment extends ListFragment {

  public interface Callbacks {
    public void onItemSelected(int id);
  }

  @Inject
  private Callbacks mCallbacks;

  @Override
  public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    IndirectInjector.inject(getActivity(), this);

    mCallbacks.onItemSelected(0);
  }
}
