这是我的布局文件
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

<android.support.design.widget.NavigationView
android:id="@+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"

app:itemIconTint="@color/navItemIconTintColor"
app:itemTextColor="@color/navItemTextColor"
app:menu="@menu/menu_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
我设置app:layout_scrollFlags
了我的CollapsingToolbarLayout
toscroll|enterAlways
并期望工具栏将像在 gapps(例如 Google Play 或 Google Magazine)中一样使用自动隐藏/显示,就像在这个示例中一样:
但我只有滚动工具栏不会自动收回,但前提是用户自己完全滚动它。查看示例:我的应用
这是我的带有 recyclerview 的片段,我将其替换为fragment_placeholder
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.moskart.mosfake.fragment.CategorySelectionFragment"
>
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/card_horizontal_margin"
android:paddingRight="@dimen/card_horizontal_margin"
/>
</LinearLayout>
谢谢你的建议!
