Webview prevent scroll up from specific height

Question

I have one webview. I know how to programmatically scroll down it when page is loaded.
My problem is that I want to prevent the user from scrolling up at the place that I programmatically scrolled down.

Any ideas?

Answer 1

Instead of programmatically scroll down do those changes in xml.

<WebView
        android:layout_marginTop="-10dp"
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

This will crop the content that you want to hide from top
