Injecting generic class with Dagger

Question

I have an abstract base class in my project

public abstract class BaseActivity<T extends BasePresenter<? extends IBaseView>> implements IBaseView{

Into which I try to inject a generic class like this:

@Inject protected T mPresenter; 

Is there any way to make dagger work with such a generic injection? Dagger generates code like:

public final class BaseActivity$$InjectAdapter extends Binding<BaseActivity>
implements MembersInjector<BaseActivity> {
    private Binding<T> mPresenter;
}

And then fails because "T cannot be resolved to a type". Is there any way to make it generate a

Binding<SomethingExtendingBasePresenter> mPresenter

in such case?

Answer 1

The only way I know of is to create a new class that extends your generic. One for each type you are interested in.

public class Foo extends BaseActivity<SomethingExtendingBasePresenter> {
}

@Inject
Foo mFoo;
