This wrap has more functionality as the wrapped lib was. The Original does only have a event when you reveal the hole object.... I thought it would be nice to have an additional event when you do your first scratch on one of the scratchitems.... The onScratching event was born
My example shows this

Very very nice, Manfred.
Scratching effect was applied to one of my first apps..eventually it could be re-tooled with your lib!

MarcoRome · May 14, 2016

Great work Don ( as usual ) +40
Look this 2 little demo:
In this first movie as i "touch" but i dont see Text in ( 0$, 1$ or 5$ )

if i write ScratchTextView1.Text i dont see this in code but i see in Design.
P.S. You forget in your demo donmanfred.png

See updated lib in Post #1. V1.0.1
You need to set the CUSTOM VIEW properties....
Text
TextColor
TextSize

Included in new example too

I should "test" it (to know the differences); anyway, I did something like this... probably 2 years ago and... not for me

It was a "Gratta e Vinci" (Scratch and win)

This is just to say: "Unfortunately at the time there was not this library"

Now it is. Time to make a nice Example app out of the lib.

Sorry Don Manfred this is escape...
"PercentageRevealed event" is feature very important for this library.
Great great work +50

i think you meant to say "Sorry Manfred i have missed this"
But i think i understand what you wanted to say.

PS: I missed your answer too

I missed this feature and told about in b4achatroom...

- I got a suggestion from @NJDude for a library which does have such a feature.
- I tried to make a wrap for it till i saw it does not work. But i copied the code from it which does the calculation and i extended this lib with the code from the other lib. It works!

V1.2 was born

MarcoRome · May 21, 2016

Great Don

Add this line to your main activity

B4X:

#AdditionalJar: com.android.support:support-v4

Make sure to have the two maven repositories installed correctly and up-to-date

@DonManfred Am aware that this thread is old but am kindly wanted to ask that PercentRevealed fixed on v1.5? It is not working for me here..
