I am using CoordinatorLayout in my activity page. In that there is ListView below the app bar. But its not working when I use ListView         
        
For the CoordinatorLayout to work properly you need the scrolling child to implement NestedScrollingChild. Such classes are NestedScrollView and RecyclerView.
To say it short - just use a RecyclerView for your scrolling content and it'll work correctly :)
P.S. As a side note, I don't see a reason why you'd use a ListView anymore. I know it's a habit and it's easier to setup (because you've done it many times), but using a RecyclerView is the recommended way anyways.
You can't scroll listview inside a nestedscrollview.Use Recyclerview with nestedscrollview

you can fix it when you add addtribute android:fillViewport="true" in android.support.v4.widget.NestedScrollView :) . This my code.
<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="none"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:fillViewport="true"
    >
    <ListView
        android:id="@+id/list_myContent"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"
        >
    </ListView>
</android.support.v4.widget.NestedScrollView>
Just put android:fillViewport="true" inside you NestedScrollView Tag
Just add android:nestedScrollingEnabled="true" tag inside your NestedScrollView.
<android.support.v4.widget.NestedScrollView
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:scrollbars="none"
  android:nestedScrollingEnabled="true">
   <ListView
      android:id="@+id/list_myContent"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:scrollbars="vertical">
  </ListView>
You listview will scroll. Hope help.
