I really wanted to write about my success with drawing something today.
Nope.
I give up.
Not entirely, of course, but for today. I tried to actually draw a line on an ImageView, and after an hour I decided that enough is enough.
I really don’t get it. I looked through the official Android tutorials to see a similar example – to no avail. I googled the error message I was getting – without success. Come on, it can’t be so hard to actually draw a freaking line on a screen!
What I tried to do was to subclass ImageView and provide my drawing magic in onDraw. For some strange reason, this didn’t work, and the line
DrawingView drawingView = (DrawingView)findViewById(R.id.drawing);
(DrawingView was my subclass, drawing_view was the ImageView in the layout) kept generating an error.
I won’t surrender; I’ll try some other approach I found on the Internet tomorrow. But for today it’s enough.
