Injection Transfuse Activity into Calltrough listener #118
Comments

Are you also injecting the MenuController into your Try this: public class MenuController implements ActivityMenuComponent {
private MenuInflater menuInflater;
private Context context; // this is of the generated class SearchActivityActivity
private Provider<SearchActivity> activityProvider;
@Inject
public MenuController(MenuInflater menuInflater, Context context, Provider<SearchActivity> activityProvider) {
this.menuInflater = menuInflater;
this.context = context;
this.activityProvider = activityProvider;
} |

Ah, so that's what causes the problem. |
|
Shoot. You'll have to break the dependency loop by either injecting Here's how to inject via the interface: @Activity
public class SearchActivity{
@Inject MenuController controller;
}
public interface MenuController {}
public class MenuControllerImpl implements ActivityMenuComponent, MenuController {}
@TransfuseModule
@Bind(type=MenuController.class, to=MenuControllerImpl.class)
public class Module{} |
|
I tried the bind based injection. No errors on compile, but the callthrough listeners aren't registered anymore. |
|
Shoot, you may have to move the ActivityMenuComponent interface to as superclass of MenuController: public interface MenuController extends ActivityMenuComponent{}
public class MenuControllerImpl implements MenuController {}Are you using |

RegisterListener is in SearchActivity: @Inject
@RegisterListener
MenuController menu;If I extend ActivityMenuComponent, I get the following error: The generated code looks like this @Generated(value = "org.androidtransfuse.TransfuseAnnotationProcessor", date = "2014-06-26T10:47+0200")
public class MenuControllerImpl$$VProxy$$0
implements MenuController, DelayedLoad<MenuControllerImpl>
{
private MenuControllerImpl delegate = null;
public void load(MenuControllerImpl delegateInput) {
delegate = delegateInput;
}
private void checkDelegate() {
if (delegate == null) {
throw new VirtualProxyException("Trying to use a proxied instance before initialization");
}
}
public boolean equals(Object object$$0) {
checkDelegate();
return delegate.equals(object$$0);
}
public int hashCode() {
checkDelegate();
return delegate.hashCode();
}
public String toString() {
checkDelegate();
return delegate.toString();
}
} |

I went ahead and duplicated this problem. I was able to make it work by changing the activityProvider back to just an activity injection and duplicating the callthrough method interface on public interface MenuController extends ActivityMenuComponent {
boolean onCreateOptionsMenu(Menu menu);
boolean onPrepareOptionsMenu(Menu menu);
boolean onOptionsItemSelected(MenuItem menuItem);
boolean onMenuOpened(int featureId, Menu menu);
void onOptionsMenuClosed(Menu menu);
}public class MenuControllerImpl implements MenuController {
private MenuInflater menuInflater;
private Context context; // this is of the generated class SearchActivityActivity
private SearchActivity activity;
@Inject
public MenuControllerImpl(MenuInflater menuInflater, Context context, SearchActivity activity) {
this.menuInflater = menuInflater;
this.context = context;
this.activity = activity;
}
//...Let me know if this gets you farther. Although this works, this is obviously not as nice as it could be... lets keep this open as a bug. What I think is not happening here is twofold, the virtual proxy analysis/generator is not climbing the inheritance tree to find the callthrough interface and the |

That worked well, thanks looking into this :) |

I just encountered the same issue, and it was difficult to track down the problem since one of the errors points to a generated file for the application class, instead of either the activity or the ActivityMenuCompat-implementing class. I would like to suggest linking to this issue in the Call-Through Events section here to save time for developers in the future: http://androidtransfuse.org/documentation.html#activity |

👍 @knutsoned, we should add this to the docs (or at least some wording to relfect this). And, one of the changes for the 0.3.0 needs to be better error reporting. |
I'd like to inject the matching transfuse activity in my menuController class like this:
The reason is that I need to call a function I defined in SearchActivity and that is supposed to stay there.
Currently above code yields the following error:
