Question

How to draw filled polygon in Android ?

Answer 1

You need to set the paint object to FILL

Paint paint = new Paint();
paint.setStyle(Paint.Style.FILL);

Then you can draw whatever you want, and it will be filled.

canvas.drawCircle(20, 20, 15, paint);
canvas.drawRectangle(60, 20, 15, paint);

etc.

For more complex shapes you need to use the PATH object.
