Overview

ScratchView

Intro

ScratchView repo is UX Design involving scratch cards like views which are scratched to reveal the information they conceal. There are two types of ScratchView

  • ScratchImageView

    • A Child of ImageView which conceals the image. Scratching over the view will reveal the hidden image.
  • ScratchTextView

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

Demo Screen

ScratchImageView ScratchTextView
ScratchImageView ScratchTextView

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.

Usage

ScratchImageView

XML
<com.cooltechworks.views.ScratchImageView
  android:id="@+id/sample_image"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background="@android:color/white"
  android:src="@drawable/img_sample2"
  />
JAVA
ScratchImageView scratchImageView = new ScratchImageView(this);

scratchImageView.setRevealListener(new ScratchImageView.IRevealListener() {
    @Override
    public void onRevealed(ScratchImageView tv) {
        // on reveal
    }

    @Override
    public void onRevealPercentChangedListener(ScratchImageView siv, float percent) {
        // on image percent reveal
    }
});

ScratchTextView

XML
<com.cooltechworks.views.ScratchTextView
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:gravity="center|end"
  android:text="@string/flat_200"
  android:textSize="15sp"
  android:textStyle="bold" />
JAVA
ScratchTextView scratchTextView = new ScratchTextView(this);

scratchTextView.setRevealListener(new ScratchTextView.IRevealListener() {
    @Override
    public void onRevealed(ScratchTextView tv) {
        //on reveal
    }


    @Override
    public void onRevealPercentChangedListener(ScratchTextView stv, float percent) {
        // on text percent reveal
    }
});

  • Get percentage of the whole scratch area

    Get percentage of the whole scratch area

    Hi and thank you for this library, it's very helpful! But I have a question, can we get the percentage or check if the whole scratch area is revealed? as for now, we only can detect the percentage of the text/image area inside the scratch view. Any help would be appreciated! Thank you very much

  • Need to tap the image to reveal instead of scratching the surface.

    Need to tap the image to reveal instead of scratching the surface.

    I created a ScratchImageView and a ScratchTextView. In order to reveal the content, I had to tap over the image and this is not equivalent to shown behaviour of scratching the image as shown on DemoScreen.

    Am I missing on something or this is the actual behaviour?
