我尝试使用 mvp 和 RXAndroid 使用 dagger 2 创建示例应用程序，一切正常，但我无法注入 Activity 以下是我的 AppComponent

@Singleton
@Component(modules = {AppModule.class})
public interface AppComponent {
    void inject(App app);

    void inject(MainActivity activity);

    void inject(ResponseService service);

    void inject(MainPresenter presenter);
}

以下是我的模块

@Module
public class AppModule {

    private App app;
    public AppModule(App app) {
        this.app = app;
    }
    private static final String API_ENDPOINT = "url here";

    @Provides
    @Singleton
    public ApiService apiService() {
        OkHttpClient client = new OkHttpClient();


        Gson gson = new GsonBuilder().registerTypeAdapterFactory(new ClassTypeAdapterFactory())
                .registerTypeAdapter(Class.class, new ClassTypeAdapter()).create();


        Retrofit retrofit = …

我想删除 Toolbar 和 TextView 之间的这个空间，如下图所示：

我尝试用户contentInsetStart，contentInsetEnd但也不起作用。这是我处理它的完整代码

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="@dimen/app_bar_height"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/ctl_news"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:contentScrim="?attr/colorPrimary"
        app:expandedTitleTextAppearance="@style/CollapsingToolbarLayoutExpandedTextStyle"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <ImageView
            android:id="@+id/iv_news_mainImage"
            android:layout_width="match_parent"
            android:layout_height="230dp"
            android:scaleType="centerCrop"
            android:src="@drawable/stripes"
            app:layout_collapseMode="parallax"
            app:layout_collapseParallaxMultiplier="0.7" />

        <android.support.v7.widget.Toolbar
            android:id="@+id/tb_news"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:layout_collapseMode="pin"
            android:contentInsetEnd="0dp"
            android:contentInsetStart="0dp"
            app:contentInsetEnd="0dp"
            app:contentInsetStart="0dp"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:titleTextAppearance="@style/Toolbar.TitleText">

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/back"
                android:gravity="top|end"
                android:textColor="@color/white"
                android:textSize="@dimen/text_huge_size" />
        </android.support.v7.widget.Toolbar>

    </android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>

谁能帮我解决
