匕首 - 类有没有注射成员 [英] Dagger - class has no injectable members

问题描述

我想匕首融入我的应用程序。我遇到了一个问题。我在运行时得到这个错误：

  java.lang.IllegalStateException：错误创建对象图：
    com.app.NavigationController没有注射成员。你想添加一个注射构造？按类com.app.fragments.LoginFragment要求
 

我试图寻找到其他类似的答案，但没有任何帮助我至今...

要绘制建筑相关的一切都实现pretty很像 Android的活动图例子。

我有两个模块 ActivityModule 和 ApplicationModule 。

  @Module（
        包括= ApplicationModule.class，
        注射= {
                MainActivity.class，
                LoginFragment.class
        }
）
公共类ActivityModule {    私人BaseActivity活动;    公共ActivityModule（BaseActivity活动）{
        this.activity =活动;
    }    @Provides
    @辛格尔顿
    NavigationController provideNavigation（）{
        返回新NavigationController（活动）;
    }
}
 

和其他

  @Module（
    注射= {
            MainActivity.class，
            LoginFragment.class}，
    完整= FALSE
）
公共类ApplicationModule {    私人上下文的背景下;    公共ApplicationModule（上下文的背景下）{
        this.context =背景;
    }    @Provides
    @辛格尔顿
    ApiService provideApiService（）{
        ....
        返回restAdapter.create（ApiService.class）;
    }
}
 

我在做什么错了？

更新：结果
添加更多细节：

片段：

 公共类LoginFragment扩展BaseFragment {    // ...    @注入
    NavigationController导航;    // ...
 

导航控制器：

 公共类NavigationController {// ...公共NavigationController（BaseActivity活动）{
    this.activity =活动;
}// ...
}
 

解决方案

问题是回答了这把匕首 GitHub的问题＃372

I'm trying to integrate Dagger into my application. And I ran into a problem. I'm getting this error at runtime:

java.lang.IllegalStateException: Errors creating object graph:
    com.app.NavigationController has no injectable members. Do you want to add an injectable constructor? required by class com.app.fragments.LoginFragment

I tried looking into other, similar answers, but nothing helped me so far...

Everything related to graph construction is implemented pretty much like in Android Activity Graphs example.

I have two modules ActivityModule and ApplicationModule.

@Module(
        includes = ApplicationModule.class,
        injects = {
                MainActivity.class,
                LoginFragment.class
        }
)
public class ActivityModule {

    private BaseActivity activity;

    public ActivityModule(BaseActivity activity) {
        this.activity = activity;
    }

    @Provides
    @Singleton
    NavigationController provideNavigation() {
        return new NavigationController(activity);
    }
}

And another

@Module(
    injects = {
            MainActivity.class,
            LoginFragment.class},
    complete = false
)
public class ApplicationModule {

    private Context context;

    public ApplicationModule(Context context) {
        this.context = context;
    }

    @Provides
    @Singleton
    ApiService provideApiService() {
        ....
        return restAdapter.create(ApiService.class);
    }
}

What am I doing wrong?

UPDATE:
Adding more details:

Fragment:

public class LoginFragment extends BaseFragment {

    //...

    @Inject
    NavigationController navigation;

    //...

Navigation controller:

public class NavigationController {

//...

public NavigationController(BaseActivity activity) {
    this.activity = activity;
}

//...
}
