以角度在画布上绘制文本

Question

如何在画布上绘制文本,如下图所示Green rectangle.

我已经完成了以下代码....但是从这段代码我可以写入文本straight.不能写文字angle.

Bitmap bmpLayered = Bitmap.createBitmap(bmpMain.getWidth(), bmpMain
                .getHeight(), Bitmap.Config.ARGB_8888);
        Canvas cv = new Canvas(bmpLayered);

Paint charPaint = new Paint();
        charPaint.setAntiAlias(true);
        charPaint.setStyle(Paint.Style.FILL);
        charPaint.setTextSize(24);
        charPaint.setColor(Color.BLACK);
        charPaint.setStrokeWidth(3);

cv.drawText("None", 570, 222, charPaint);

请帮我解决这个问题.

谢谢.

Answer 1

cv.save();
cv.rotate(-45, x, y);
cv.drawText("your text here", x, y, paint);
cv.restore();

其中cv是对画布的引用,x&y是你想要绘制的点.
