Question

我正在构建具有购物车菜单项且所有产品都按片段打开的android购物应用，我想在产品片段和其他片段上设置MainActivity菜单项。

因此，用户很容易从产品视图片段中打开购物车。代码如下

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    view = inflater.inflate(R.layout.product_view_fragment, null);
    setHasOptionsMenu(true);
    AppCompatActivity activity = (AppCompatActivity) getActivity();
    activity.setSupportActionBar(toolbar);
    getActivity().invalidateOptionsMenu();
    toolbar = (Toolbar)view.findViewById(R.id.toolbar);
    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            getActivity().onBackPressed();
        }
    });
    this.context = getContext();
    String id=getArguments().getString("message");
    //String size=getArguments().getString("size");
    viewPager = (ViewPager)view.findViewById(R.id.viewPager);
    SessionManager sessionManager = new SessionManager(getContext());
     email = sessionManager.getUserDetails().get("id");
    sliderDotspanel = (LinearLayout)view.findViewById(R.id.SliderDots);

    GetOneProduct(id);
    return view;
}
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
xmlns:segmentedgroup="http://schemas.android.com/tools"
android:orientation="vertical"
android:clickable="true"
android:background="@color/colorWhite"
android:layout_height="wrap_content">
<android.support.design.widget.AppBarLayout
    android:id="@+id/appBarLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@android:style/Animation.Activity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:navigationIcon="?attr/homeAsUpIndicator"
        app:popupTheme="@style/AppTheme.PopupOverlay"
        app:titleTextColor="@color/Black" />
</android.support.design.widget.AppBarLayout>

我假设您使用单一活动方法。然后，您的活动应在其布局中包含“工具栏”，如下所示。

@Bean
@Profile("export")
public AnnotationGatewayProxyFactoryBean exportingOutboundGateway() {
    return new AnnotationGatewayProxyFactoryBean(ExportingOutboundGateway.class);
}

...

public interface ExportingOutboundGateway {

    @Gateway(requestChannel = "exportChannel")
    void send(String request);

}

然后根据需要在活动中设置工具栏。

为什么我的工具栏没有在片段上设置菜单？
