推荐答案

当然可以。您需要先缩放画布。尝试了这一点：

sure can. You will need to scale the canvas first. Try this out:

paint.setTextSize(44);
int cx = this.getMeasuredWidth() / 2;
int cy = this.getMeasuredHeight() / 2;
paint.setColor(Color.RED);
canvas.drawText("Hello", cx, cy, paint);

canvas.save();
canvas.scale(1f, -0.5f, cx, cy);
paint.setColor(Color.GRAY);
canvas.drawText("Hello", cx, cy, paint);
super.onDraw(canvas);
canvas.restore();

尝试不同的值规模为Y值来获得你想要的效果。

Try different values for the scale Y value to get effect you want.
