Dagger 2 How to inject one class to multiple components using Sub components?

问题

Can any please provide example code to achieve this scenario using sub components. In MyActivity i need to fulfill dependencies from multiple components. As you can see in below code MyActivity requies injection from compA via module classA and compB via module classB.

@Component(modules = classA.class)
interface compA
{
void inject(MyActivity target);
}

@Component(modules = classB.class)
interface compB
{
void inject(MyActivity target);
}

I have been trying many different things for quite some time. I have also read official docs regarding sub components but unable to understand how to do for my scenario. Please help

There are many ways to do this stuff. include modules is one of that. we have to modules AndroidModules and NetworkModules.

@Module(includes = AndroidModules.class)
public class NetworkModules {
//Here two module are marge ....
}

Now in My component

@Component(modules = NetworkModules.class)
public interface NetworkComponent {
    void inject(MyActivity activity);
}

You could try it like this,

@Component(
    modules = {
        ApplicationModule.class,
        MainModule.class
    }
)
public interface compA
{
void inject(MyActivity target);
}
