Question

I have the following layout:

    <?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="br.com.myproject.view.fragment.ProductActivityFragment"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/app_bar_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        android:fitsSystemWindows="true">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            tools:layout_scrollFlags="scroll|exitUntilCollapsed"
            tools:contentScrim="?attr/colorPrimary"
            tools:expandedTitleMarginStart="48dp"
            tools:expandedTitleMarginEnd="64dp"
            android:fitsSystemWindows="true">

            <ImageView
                android:id="@+id/ivImgProduct"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:scaleType="centerCrop"
                android:fitsSystemWindows="true"
                tools:layout_collapseMode="parallax"/>

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                tools:layout_scrollFlags="scroll|enterAlways"
                tools:popupTheme="@style/ThemeOverlay.AppCompat.Light"
                tools:layout_collapseMode="pin">
            </android.support.v7.widget.Toolbar>

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

    <android.support.v7.widget.RecyclerView
            android:id="@+id/rvProductActions"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            tools:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior">

        </android.support.v7.widget.RecyclerView>

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

The RecyclerView is getting on the Toolbar are staying with an appearance "overlapped". The scroll both RecyclerView as the CollapsingToolbarLayout not working. I'm trying to leave my layout with the behavior as this example link , but using RecyclerView.

Answer 1

After many attempts I used a library called Android-ObservableScrollView and it worked. It is simpler to use, provides several examples and a single component already has the desired effect. Scroll content has to be greater than the empty screen space for the scroll to take effect because it does not have the bounce effect of iOS.

您必须将app：layout_behavior =“ @ string / appbar_scrolling_view_behavior”添加到您的回收站视图
