You need to use a canvas to get each section of the image, see help on canvas here... https://www.b4x.com/android/help/drawing.html#canvas
They're may be image libraries that could do this but I'm not familiar with which ones to use. What are you wanting to do with the sections of the image?
If I understand your problem well, you want an event raised when you touch the ImageView.
I would use one Panel with the whole image instead of a set of ImageViews.
And in the Touch event calculate from the X and Y coordinates the part of the image where you touch it and act according to this.
If it's a fixed bitmap map, I'd go the route of hit colors.
Behind the scenes, I'd have an additional bitmap, with the same size as the first, where each country is a single, unique color. Finland red, Egypt white, Germany black and so on. Then, when you get a click on the map, check the color on the same coordinate on the color hitmap, and reference to a table. So, a click on a red pixel means Finland.
To light up the countries, I would then try to generate an alpha overlay map from the color map. In other words, (assuming we selected Finland), create an alpha overlay where all the red pixels in the hitmap are fully transparent and everything else is, say, 75% transparent, and color of the entire overlay is black. Then, just overlay that map on the display map. Finland will be at full brightness, the rest will be slightly dimmed. (Of course, these overlay maps could also be pregenerated, but that would require a full size image for each country, so it would be pretty wasteful.)
(bonus points to whoever can spot the hidden reference in this post)
The same technique (hit colors) is useful in many other applications. I once made a remote control application for Windows, with user defined controls. Basically, it went like this:
* One display bitmap with the image of the remote control.
* One bitmap with the color map (easily done by coloring the display image).
* On script file, with "events" for each hit color.
So, when the user clicked a button with the hit color red, I read the script file and ran the script for red. The script language was VBScript with various specific enhancements for sending remote key presses, DDE messages, TCP/IP messages and so on.
Dead simple, and yet a quite powerful application that was easy (for a power user) to customize. For example, setting up a minimal remote control for VLC took me about ten minutes, most of it in PaintShop.
One small note if you do this on Windows: Windows has a bug, in that, when you ask for the color of a pixel, it does not return the color as it is in the bitmap, it returns the color which the pixel is displayed as on screen, which depends on bit depth, gamma correction and so on. This means that either you need to do your own bitmap decoding (easy if you use uncompressed BMP) or test the color with a certain allowance for variation. Extremely annoying, and wrecks a lot of otherwise simple solutions.
