Coordiantor Layout not working with Listview

Question

I have a listview which is the scrolling part in my activity .The problem is my listview is not scrolling .I have to hold the the appbarlayout to scroll.Here is my code-

The mainactivity.xml

<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:fitsSystemWindows="true"
tools:context=".MainActivity">

<android.support.design.widget.AppBarLayout android:layout_height="wrap_content"
    android:layout_width="match_parent" android:theme="@style/AppTheme.AppBarOverlay"
    android:fitsSystemWindows="true">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/htab_collapse_toolbar"
        android:layout_width="match_parent"
        android:layout_height="256dp"
        android:fitsSystemWindows="true"
        app:contentScrim="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical" android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorAccent"
        app:layout_collapseMode="parallax">

        <com.facebook.drawee.view.SimpleDraweeView
            android:id="@+id/image_view"
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:layout_gravity="center"
            android:fitsSystemWindows="true"/>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:weightSum="3"
            android:layout_gravity="bottom"
            android:paddingBottom="16dp">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="Followers"
                android:textAlignment="center"
                android:textAppearance="?android:attr/textAppearanceLarge"/>

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="Points"
                android:textAlignment="center"
                android:textAppearance="?android:attr/textAppearanceLarge"/>

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text="Following"
                android:textAlignment="center"
                android:textAppearance="?android:attr/textAppearanceLarge"/>

        </LinearLayout>

    </FrameLayout>

     <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="104dp"
        android:gravity="top"
        android:minHeight="?attr/actionBarSize"
        app:layout_collapseMode="pin"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:titleMarginTop="13dp" />

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

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

<ListView
    android:id="@+id/list_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

<android.support.design.widget.FloatingActionButton android:id="@+id/fab"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    android:layout_gravity="bottom|end" android:layout_margin="@dimen/fab_margin"
    android:src="@android:drawable/ic_dialog_email" />

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

The java code-

public class MainActivity extends AppCompatActivity { 
ListView listView;
String[] strings={"Something","Everything","Nothing","Ok","Maybe","Whatever","Does it matter","Mybe again","Nothing","Nothing","Nothing","Nothing"};
ArrayAdapter<String> adapter;
com.facebook.drawee.view.SimpleDraweeView image;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    image= (SimpleDraweeView)findViewById(R.id.image_view);
    image.setImageURI(Uri.parse("https://www.google.co.in/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png"));
    listView= (ListView) findViewById(R.id.list_view);
    adapter=new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,strings);
    listView.setAdapter(adapter);

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });
   }
}

My gradle dependency-

compile 'com.android.support:design:23.1.0'

This is because ListView does not support the NestedScrollingChild interface, which is required to deliver the scroll events that AppBarLayout and others rely on to manage their positioning.

The simplest option is to switch your usage from ListView to RecyclerView—which already implements the necessary interfaces. A more complicated choice would be to attempt to extend ListView and implement NestedScrollingChild from the support library (docs).
