I just experimented real quick on implimenting the PolyToPoly method
to the MapViewCompassDemo.java APIDemo and it worked!
I added mMatrix as a variable for the class:
private Matrix mMatrix = new Matrix();
added a concat call to the protected void dispatchDraw() function:
canvas.concat(mMatrix);
and finally added the matrix transformation call to the end of the
onLaonLayout() function:
float src[] = new float[] { 0, 0, width, 0, width, height, 0,
height };
float dst[] = new float[] { 0, 0, width, 0, width*2, height, -width,
height };
mMatrix.setPolyToPoly(src, 0, dst, 0, src.length >> 1);
and here's what it looks like:
