问题
I want to create a clickable image, my image has some different clickable parts in it, like this one:
I want to draw a custom shape like :
A,B,C,D,E,F
and make sure when user click on of this something happen.
the problem is I don't have any kind of idea to, how create shapes like the shapes in the image make sure it just fix on the image and in different screen size don't see a massed up thing.
回答1:
Will there be more than many of such images?
If no I suggest you to create mask image for each region where black part of image represents the region and white part excludes rest.
To draw image:
- create custom View
- in constructor don't forget to use setWillNotDraw to true so you can do custom drawing
- override View.onDraw method where you can draw main image and all others with some filters via setColorFilter.
To handle click events:
- override onTouchEvent method
- get touch position
- compare touch position with point color in mask image
To optimise:
- create mask image downscaled by some scale factor
- during comparison divide touch position by scale factor
This is not ideal, but solution with vectors is non trivial I think

Take it as image and setOnclickListner for that image
