Android App Halp

hi /prog/,


Actually, I got some problem witrh building my Android App. I want to create a mini-game in my app. It will works like this:

- At the begining an image appears
-then the app ask the user to zoom-in the picture
- then a grid will appear and seperate the picture into pixels (like the one million pixel wall for example)
-the user will have to choose one "pixel" of the grid and he will win (or not) some points.

It seems quite simple but i got some issues:

-How can i create this grid? (GridLayout? )
-How can i put an invisible Grid (opacity=0) on a picture ? (Grid Layout Option Maybe ? )
- How can i use the zoom-in option to be as smooth(natural and simple) as possible?
-What should i do in order to turn the Grid opacity to 1 when "the Zoom in" effect has been done ?

General tips and tricks are welcomed. Explanations will be great.

Thanks in advance.

P.S.: Sorry for my English. It's not really my main language but I hope that I am still understandable.
