I can't find any good guide on how to use it on a canvas,
can you give me a start please?

Ok.

I arrived here:

TextPaint textPaint = new TextPaint();
StaticLayout textLayout = new StaticLayout("long long long string", textPaint, getWidth(), Alignment.ALIGN_NORMAL, 1, 0, false);
textLayout.draw(g);

the red "getWidth()" means that my string should wrap all over the canvas width,
but how can I set that the string should be drawn starting from the (X,Y) point?

canvas.translate(dx, dy)

please don't tell me that I need to translate the entire canvas to draw a string.

I think that translating the entire canvas every time I need to write something is not efficient,
is not elegant, is not smart.
I'm using

canvas.save();
layout.draw();
transalte();
canvas.restore();

is there a more efficient way to do it?

ok, maybe its not elegant, but how do you know its not efficient ?

I'm supposing it since I need to save the canvas, draw my textPaint, restore the canvas every time I need to output a string, it doesn't seem so efficient, if there isn't a better way, ok I'll use this way.
