I have this very simple layout:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/tools"
android:id="@+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ActionBarThemeOverlay">
<!--<include layout="@layout/include_toolbar_actionbar" />-->
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/background"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
I add a Fragment
with a standard RecyclerView
into fragment_container
. Unfortunately, the Toolbar
is always hide, I can't understand why?
Thank you very much for your help guys!
You could try this: solution from similar question.
Basically, you have to use android.support.v4.widget.NestedScrollView
instead of ScrollView
(in your fragment) and implement app:layout_behavior="@string/appbar_scrolling_view_behavior"
inside your NestedScrollView xml.
