android开发文字转bitmap的实现

public static Bitmap generateBitmap(String text,int textSizePx,int textColor){ TextPaint textPaint = new TextPaint(); textPaint.setTextSize(textSizePx); textPaint.setColor(textColor); int width = (int) Math.ceil(textPaint.measureText(text)); Paint.FontMetrics fontMetrics = textPaint.getFontMetrics(); int height = (int) Math.ceil(Math.abs(fontMetrics.bottom) + Math.abs(fontMetrics.top)); Bitmap bitmap = Bitmap.createBitmap(width,height, Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(bitmap); canvas.drawText(text,0,Math.abs(fontMetrics.ascent),textPaint); return bitmap; }
