Question

我的问题是将片段制作成全屏并在其上应用自定义主题。我试过这种方式却无法得到结果。 RssDetailViewFragment.cs包含以下代码行：

public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        // Use this to return your custom view for this Fragment
        // return inflater.Inflate(Resource.Layout.YourFragment, container, false);

        // create ContextThemeWrapper from the original Activity Context with the custom theme
        Context contextThemeWrapper = new ContextThemeWrapper(Activity, Android.Resource.Style.ThemeLightNoTitleBarFullScreen);

        // clone the inflater using the ContextThemeWrapper
        LayoutInflater localInflater = inflater.CloneInContext(contextThemeWrapper);

        rootView = localInflater.Inflate(Resource.Layout.RSSFeedDetails, null, false);


        // inflate progressbar
        progressBar = rootView.FindViewById<ProgressBar>(Resource.Id.progress_bar);
        progressBar.Visibility = ViewStates.Visible;

        // setting control toolbar
        Toolbar toolbar = rootView.FindViewById<Toolbar>(Resource.Id.top_control_toolbar);
        ((AppCompatActivity)this.Activity).SetSupportActionBar(toolbar);
        // setting icon on toolbar            
        toolbar.SetNavigationIcon(Resource.Drawable.ic_back20);
        toolbar.SetBackgroundColor(Resources.GetColor(Resource.Color.primary));

        View navigationIcon = toolbar.GetChildAt(1); //NavigationIcon

和我的RssFeedDetals的xml文件是

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="60dp"
    android:orientation="vertical"
    android:background="@color/viewBackground">
    <include
        android:id="@+id/top_control_toolbar"
        layout="@layout/TopControlToolbar" />            
    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/viewBackground">
        <WebView
            android:id="@+id/webview"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />
    </ScrollView>
    <ProgressBar
        android:id="@+id/progress_bar"
        style="@android:style/Widget.DeviceDefault.ProgressBar"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:visibility="invisible" />
</LinearLayout>

要问这个问题的主要方法是在Min Sdk 15 plus上使片段全屏显示。

谢谢。

我想要隐藏app的activity和statusBar工具栏，并用片段视图覆盖该区域。

当您展示RssDetailViewFragment时，您可以隐藏Statusbar和Toolbar，如下所示：

    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        SetHasOptionsMenu(true);

        //Hide the StatusBar
        WindowManagerLayoutParams attr = Activity.Window.Attributes;
        attr.Flags = WindowManagerFlags.Fullscreen;
        Activity.Window.Attributes = attr;

        //Hide the ToolBar
        ftoolbar = (V7Toolbar)Activity.FindViewById<V7Toolbar>(Resource.Id.toolbar);
        ftoolbar.Visibility = ViewStates.Gone;

        //Load views for this Fragment
        View view = LayoutInflater.From(Activity).Inflate(Resource.Layout.MGradesView, null);
        return view;
    }

如何将内置或自定义主题应用于活动中的片段？
