java - Design lib - CoordinatorLayout/CollapsingToolbarLayout with GridView/listView

Question

This might be silly question but I didn't understand Design lib well. I am following this reference to create below layout. The Blue area should work as parallax when I scroll the GridView. But when I scroll grid View nothing happens in AppBarLayout.

But This works with NestedScrollView and RecyclerView

Below is My Layout file-

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    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/appbar"
    android:layout_width="match_parent"
    android:background="#500403"
    android:layout_height="@dimen/detail_backdrop_height"
    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"
        android:background="#122453"
        app:layout_scrollFlags="scroll|exitUntilCollapsed"
        android:fitsSystemWindows="true"
        app:contentScrim="?attr/colorPrimary"
        app:expandedTitleMarginStart="48dp"
        app:expandedTitleMarginEnd="64dp">


        <ImageView
            android:id="@+id/backdrop"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scaleType="centerCrop"
            android:fitsSystemWindows="true"
            app:layout_collapseMode="parallax" />
        <ImageView
            android:id="@+id/backdrop1"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:scaleType="fitCenter"
            android:fitsSystemWindows="true"
            android:layout_gravity="center"
            android:src="@drawable/bar_offline"
            app:layout_collapseMode="parallax" />


        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="#982223"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_collapseMode="pin" />
    </android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>

  <GridView
      android:id="@+id/grid"
      android:numColumns="4"
      android:background="#367723"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      app:layout_behavior="@string/appbar_scrolling_view_behavior"
      />
<android.support.design.widget.FloatingActionButton
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    app:layout_anchor="@id/appbar"
    app:layout_anchorGravity="bottom|right|end"
    android:src="@drawable/bar_offline"
    android:layout_margin="@dimen/fab_margin"
    android:clickable="true"/>
</android.support.design.widget.CoordinatorLayout>

Any help would be appreciated.

Answer 1

With ListView/GridView, it works only on Lollipop by following code-

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
     listView.setNestedScrollingEnabled(true);
}

I think for Now CoordinatorLayout works only with RecyclerView and NestedScrollView

EDIT :

use -

ViewCompat.setNestedScrollingEnabled(listView/gridview,true); (add Android Support v4 Library 23.1 or +)
