How to programmatically include the mouse cursor in android tv

Issue

I use Webview, which loads random sites. For good navigation I need to turn on the mouse cursor, which will be controlled by D-pad, but I did not find information on how to do it, maybe someone can have developed such navigation, I will be grateful for any help.

Solution

To Enable cursor pointer in android tv webview by creating custom pointer layout

then put the webview inside custom cursor layout in XML

<com.example.webviewtvapp.CursorLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/cursorLayout">

    <WebView
        android:id="@+id/webView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</com.example.webviewtvapp.CursorLayout>
