android - 未注册注入。您必须将其显式添加到您的模块之一中的“注入”选项中

Question

嗨，我是 dagger 的新手，并试图用简单的 android 应用程序来研究它。

即使有注入此视图的模块，我也会从标题中得到错误。谁能帮我弄清楚为什么它不注入视图？

这是我的应用程序的主要模块：

@dagger.Module(injects = {App.class, MainActivity.class}, complete = false)
public class AppModule {
    private final App app;
    public AppModule(App app) { this.app = app; }
    @Provides @Singleton public App provideApp() { return app; }
}

另一个注入我观点的模块：

@Layout(R.layout.sidemenu)
public class SidemenuScreen implements Blueprint{
    @Override public String getMortarScopeName() { return getClass().getName(); }
    @Override public Object getDaggerModule() { return new Module();}

    @dagger.Module(injects= SidemenuView.class, addsTo = AppModule.class)
    public static class Module { 
       public Module() {}
    }

    @Singleton public static class Presenter extends ViewPresenter<SidemenuView> {
        @Inject Presenter() {}
        @Override protected void onLoad(Bundle savedInstanceState) {super.onLoad(savedInstanceState); }
        @Override protected void onSave(Bundle outState) { super.onSave(outState); }
    }
}

如您所见， SidemenuScreen.ModuleinjectsSidemenuView和 addTo AppModule。我错了吗 ？

ObjectGraph 在onCreate()我的 Application 类的方法中是这样创建的：

    ObjectGraph objectGraph = ObjectGraph.create(new AppModule(this));
    objectGraph.inject(this);
    rootScope = Mortar.createRootScope(BuildConfig.DEBUG, objectGraph);

应该注入的视图

public class SidemenuView extends LinearLayout {
    @Inject SidemenuScreen.Presenter presenter;

    public SidemenuView(Context context) {this(context, null); }
    public SidemenuView(Context context, AttributeSet attrs) { this(context, attrs, 0); }
    public SidemenuView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        Mortar.inject(context, this);
    }
}

和使用所有这些东西的活动：

public class MainActivity extends Activity {
    private MortarActivityScope activityScope;
    @Inject App app;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        Blueprint screen = getScreenFromIntent(getIntent());

        if (screen != null) {
            MortarScope parentScope = Mortar.getScope(getApplication());
            activityScope = Mortar.requireActivityScope(parentScope, screen);
            activityScope.onCreate(savedInstanceState);

            Mortar.inject(this, this);
        }

        SlidingMenu menu = new SlidingMenu(this);
        menu.attachToActivity(this, SlidingMenu.SLIDING_WINDOW);
        menu.setMenu(R.layout.sidemenu);
    }
}

这里使用了这个滑动菜单库：

因此，当menu.setMenu(R.layout.sidemenu);调用它时，它会膨胀视图并从发生错误Mortar.inject(context, this);的构造函数中调用。SidemenuView

这是后台堆栈：

Answer 1

所以，我addsTo从子模块中删除，添加complite=false, library=true到子模块并添加includes，AppModule现在它可以工作了。但我仍然不明白为什么它不像我以前那样工作。它的完成方式有点不方便，因为每次我实现新模块时，我都需要去AppModule并将这个模块添加到包含的模块列表中。它打破了 Open/Closed 原则，所以如果有办法添加新模块，我仍然很感兴趣addsTo=AppModule.class。

有什么建议么 ？谢谢。

Answer 2

我遇到了同样的问题，我想我发现了为什么会这样。随着includes您将子模块添加到 main AppModule。随着addsTo您告诉 IDE 解析器您的子模块扩展了，Appmodule但您需要手动创建子图。

我不知道它是否足以从子模块创建一个新图形，ObjectGraph.create(new Submodule());它会自动包含用addsTo. 如果它不起作用，您需要手动创建一个子图parentGraph.plus(new Submodule())

Answer 3

为什么不在你的AppModule中注入SidemenuView呢？
