Call getChildFragmentManager inside EBean class using AndroidAnnotation

Question

I want to create a @EBean class with all functions related to show and hide ProgressDialog and DialogFragment. Ex: I need to show the ErrorDialogFragment inside a Fragment, so getChildFragmentManager() is needed in this below code:

ErrorDialogFragment.showDefaultDialog(getChildFragmentManager(),
                    "Device is disconected!");

Is there a way to call getChildFragmentManager() inside the @EBean class?

Answer 1

@EBean
public class YourBean {

  @RootContext
  FragmentActivity activity;

  public void showDialog() {
    activity.getSupportFragmentManager(). ...
  }
}

However make sure you only inject this bean to a FragmentActivity, because otherwise the Activity itself will not be injected into the bean.

Edit: You cannot inject the FragmentManager nor the Fragment to the bean with annotations. You have to create a setter method for that:

@EBean
public class YourBean {

  private FragmentManager fragmentManager;

  public void showDialog() {
    ErrorDialogFragment.showDefaultDialog(fragmentManager,
                "Device is disconected!");
  }

  public void setFragmentManager(FragmentManager fragmentManager) {
    this.fragmentManager = fragmentManager;
  }
}

In your Fragment:

@AfterInject
void afterInject() {
  yourBean.setFragmentManager(getChildFragmentManager());
}
