Contextual action bar does not overlay my toolbar

Question

I have created an activity and set toolbar as the actionbar which i have positioned at the bottom.

Inside that activity, I have a listview that contain some data.

Problem is, when I long press a list item, contextual action bar appears at the top instead of overlaying my toolbar which is positioned at the bottom.

my activity theme

<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- Base application theme. -->
<style name="myActivityTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="android:windowActionModeOverlay">true</item>
</style>

my toolbar

<android.support.v7.widget.Toolbar
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:id="@+id/toorbar"
    android:background="@android:color/white"
    android:layout_gravity="bottom">
</android.support.v7.widget.Toolbar>

my activity

protected void onCreate(Bundle savedInstanceState){
    ToolBar toolbar =(ToolBar) findViewById(R.id.toolbar)
    setSupportActionBar(toolbar)
}

What should i do to make CAB overlay my toolbar?

EDIT

This is onCreateActionMode method in my class that handle long clicks

private class Selector implements AbsListView.MultiChoiceModeListener{

    @Override
    public boolean onCreateActionMode(android.view.ActionMode mode, Menu menu) {
        mode.getMenuInflater().inflate(R.menu.my_activity_menu,menu);
        toolbar.setVisibility(View.VISIBLE);
        return true;
    }

Answer 1

If you want the Contextual ActionBar overlap over Toolbar then use this

<item name="windowActionModeOverlay">true</item>

instead of

<item name="android:windowActionModeOverlay">true</item>

Answer 2

This worked For me,

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

            <item name="windowNoTitle">true</item>
            <item name="windowActionBar">false</item>
            <item name="colorPrimary">@color/colorPrimary</item>
            <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
            <item name="colorAccent">@color/colorAccent</item>
            <item name="windowActionModeOverlay">true</item>

     </style>
