编辑：

Bitmap photo = (Bitmap) data.getExtras().get("data"); 
//create bitmap with a canvas
Bitmap newPhoto = Bitmap.createBitmap(photo.getWidth(),photo.getHeight());
Canvas canvas = new Canvas(newPhoto);
canvas.drawBitmap(photo,0,0,null);
//draw the text
Paint paint = new Paint();
//paint.setColor(Color.BLACK);
canvas.drawText("write bla bla bla",x,y,paint);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
newPhoto.compress(Bitmap.CompressFormat.PNG, 100, stream);
//get bytes from stream and send to your server
