I want to make a star shape for my project.
and I searched so, now I can make finally star shape by using canvas.

but next what I want is really really difficult to me. It`s so nightmare.
I tried and searched but nothing works for me.

what I want is star have to consist of lines with no background color.
only line.. across the line..

And then one line is expressed and fade, the next line is created and fade again, then the line is created and then fade again, and I want it to be permanent this action. Until I leave this activity's screen to another.
