This looks great Mona! Glad to see you were able to complete this assignment. Hope you found it useful in solidifying your understanding of custom views a little bit. Let me know if you have any questions or areas of the code you'd like feedback on. See you in class,

I had questions about the color selector buttons on the bottom. I think I can use a custom view for that too right? And then use styles and drawables to draw small colored circles. But how would I be able to detect which color's circle I clicked on? Use pre-defined coordinates mapped to colors?

My current approach is ugly and inconsistent image buttons and I'm sure there's a better approach.

You could draw the rectangles and circles using the onDraw method and painting with the canvas rather than using drawables too. Imagine you had an array of colors and you draw the rectangles with colors programmatically based on that array. Since you have the width and height of each rectangle and which color it represents, you can then hook into onTouchEvent and use the x/y to determine the selected color.

Yep this is an example of where a custom drawn view would work pretty well and reinforce the learning from this assignment.
