问题描述
这是我目前所拥有的并且有效：
This is what I currently have and it works:
@FragmentScope
@Component(dependencies = {FacebookComponent.class},
modules = {FragmentFacebookLoginModule.class})
public interface FragmentFacebookLoginComponent {
void inject(FragmentFacebookLogin fragment);
}
现在我想添加另一个依赖项。我把它更改为：
Now I want to add another dependency. I changed it to this:
@Component(dependencies = {FacebookComponent.class, AnotherComponent.class},
modules = {FragmentFacebookLoginModule.class})
但现在我收到此错误消息：
But now I get this error message:
我该如何解决这个问题？我如何拥有多个依赖项？
How can I solve this? How can I have more than one dependencies?
如果我从一个组件中删除范围，我会收到以下错误消息：
If I remove the scope from one component I get this error message:

最后，我创建了一个具有正确范围的AppComponent，让FacebookComponent和AnotherComponent扩展这个AppComponent。
At the end I created a AppComponent with the right scope and let FacebookComponent and AnotherComponent extends this AppComponent.
FacebookComponent和AnotherComponent没有拥有它自己的范围（我将其删除）。
FacebookComponent and AnotherComponent does not have it's own scope (I removed it).
现在看起来像这样：
@AppScope
@Component
public interface AppComponent {
}
@Component(modules = {FacebookModule.class})
public interface FacebookComponent extends AppComponent {
}
@Component(modules = {AnotherModule.class})
public interface AnotherComponent extends AppComponent {
}
@FragmentScope
@Component(dependencies = {FacebookComponent.class, AnotherComponent.class},
modules = {FragmentFacebookLoginModule.class})
public interface FragmentFacebookLoginComponent {
void inject(FragmentFacebookLogin fragment);
}
