concatenating android canvas

I am looking for an example for constructing a canvas with multiple bitmaps(kind of in a grid pattern).

would I need to create a single bitmap that holds all of the other bitmaps on top or can I just place each bitmap "into" the canvas (similar to concatenating a string)?

note: that I will also be placing additional images ontop of this constructed canvas (probably other bitmaps) would this cause any additional issues, or can I just add those right on-top?

Solution

  • You can possibly have an View with the onDraw(Canvas canvas) method drawing the grid you want using the drawBitmap(...) collection of methods of the Canvas class.

    EDIT: This way you have to deal with z-order and all the positioning of course
