那些遇到过的问题

没有注册注册.您必须将其显式添加到其中一个模块的"注入"选项中

ole*_*men 5 android dagger mortar

嗨,我是新来的匕首,并试图用简单的Android应用程序研究它.

即使有注入此视图的模块,我也会从标题中收到错误.任何人都可以帮我弄清楚它为什么不注入视图？

这是我的app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; }
}

另一个注入我视图的模块:

@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); }
    }
}

正如你可以看到SidemenuScreen.Module注入SidemenuView和添加AppModule.我错了吗 ？

ObjectGraph是在onCreate()我的Application类的方法中创建的:

    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 Sliding菜单库:

因此,当menu.setMenu(R.layout.sidemenu);调用它时会膨胀视图,并Mortar.inject(context, this);从SidemenuView发生错误的构造函数中调用.

这是一个backstack:

因此，我addsTo从子模块中删除，添加complite=false, library=true到子模块中，然后添加includes，AppModule现在它可以工作了。但我仍然不明白为什么它不像我之前那样工作。完成的方式有点不方便，因为每次我实现新模块时，我都需要转到AppModule并在包含的模块列表中添加该模块。它打破了开放/封闭原则，因此我仍然对是否有一种方法可以使用addsTo=AppModule.class.

有什么建议 ？谢谢。
