The video demonstrates how to convert a TextView to a WebView using the loadData API in HTML MIME type. This conversion is performed using the Java package com.programmerworld.textviewtowebview by creating a ‘MainActivity’ class with TextView and WebView properties. Then, in a method called ‘buttonGTextViewToWebView’, the TextView is converted into a string and loaded as ‘text/html’ into the WebView. The corresponding XML design layout uses a ConstraintLayout containing a TextView, Button, and WebView. For queries or suggestions, viewers can contact through the given website or email.
