I am new to Android development, and I as I am just starting out I am trying to do a bunch of simple projects to get my bearings. One thing I thought I would like to do, since it would be useful to me, is develop a small app that will display a grid over an image that I specify. However, when I search on Google for anything about Android and "grid," the search results are cluttered with things about the gridview layout. Therefore I cannot seem to find out how best to do this.

Can anyone give me any general ideas what I will need to do it? Are there any "grid widgets" or other things I can use to draw a black grid on my screen and overlay it on top of a photograph or other image that I will specify at runtime?

Any help appreciated.

Thanks in advance!
