  • ScratchTextView

    • A Child of TextView which conceals the text. Scratching over the view will reveal the hidden text.

Useful Methods

Both the views have following three methods which are useful to reveal or determine whether revealed and listener during revealing the hidden text/image.

  • isRevealed() – tells whether the text/image has been revealed.
  • reveal() – reveals the image/text if not revealed yet.
  • setRevealListener(IRevealListener) – a callback listener interface which gets called back when user reveals the text/image through onReveal() method.
