Java – Hides the search bar when the ListView scrolls

How to add a search bar in a listView, hidden when scrolling?

Here is my code xml:

<LinearLayout 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:orientation="vertical">

<android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="50dp">

<SearchView
        android:id="@+id/maBtnSearch"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:iconifiedByDefault="false"
        android:queryHint="Search User" />

<ListView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/listView">
    </ListView>

</LinearLayout>

Here is my full layout code above, thanks for your help

Try this. Here the searchview is placed on the toolbar. Change the code according to your purpose.

    android:id="@+id/coordinator"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

        android:layout_height="match_parent"

<android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
