沿此线的东西吗？将位图绘制到画布并绘制文本然后保存？

drawingCache = Bitmap.createBitmap(300, 400, Bitmap.Config.ARGB_8888); 

Canvas canvas = new Canvas(drawingCache); 
Paint paint = new Paint(); 

// Draw your bitmap to the canvas 
canvas.drawBitmap(bitmap, 0, 0, paint); 

Paint watermarkPaint = new Paint(); 
watermarkPaint.setColor(Color.WHITE); 
watermarkPaint.setAlpha(150); 
watermarkPaint.setTextSize(30); 
watermarkPaint.setTextAlign(Paint.Align.LEFT); 
watermarkPaint.setFlags(Paint.ANTI_ALIAS_FLAG); 

canvas.drawText("Watermark", 100, 100, watermarkPaint);
