title: creating overlapping textview and webview
body: <p>I have an app layout wherein i am using webview as a base with assets folder containing html files, everything is working great.
  what i wish is to get a dynamic textview in same place as webview by default on activity launch, but when a user click on button i want to remove text view and replace the same with webview. can any one help me.
  tried way:- I though of making two similar layouts and user response on button next same layout activity opens with webview. it lengthy way but manageable by me.</p>
