exploring custom view functionalities.Here is a simple app through which i was learning how to draw with canvas and paint. A paint object describes how to draw whereas the canvas is where to draw, just a piece of paper.
Here i have implemented some functionalities like:
-
Drawing a serie of custom circles with spacing between them. the has the ability to fit into any screen resolution.Thank to onMeasure method where i used the availabe dimension provided by the sytem to draw on.
-
Handling touch event. when a user tap on paticular circle shape , it will automatically fill in the shape if this one was previously empty and empty if if was filled in.
-
Using style able resource to easily handle some functionalites such as color and dimensions where i had to deal with the conversion from independant pixel and physical pixel because the custom view is more likely to recognise physical pixel which displays differently across different devices.
-
Allowing the option of type shape to display: stars or circles
