这里您所拥有的图像被带到画布上。现在画布用于通过使用类似于

Here the image you are having is taken onto a canvas. Now the canvas is used to modify the image by writing something on it using something like

Paint paint = new Paint(); 
paint.setColor(Color.WHITE); 
paint.setStyle(Style.FILL); 
canvas.drawPaint(paint); 

paint.setColor(Color.BLACK); 
paint.setTextSize(20); 

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss");
String currentDateandTime = sdf.format(new Date());
canvas.drawText(currentDateandTime , 10, 25, paint);

这可能有助于您将图像绘制到图像上。
试试看。

This may help you to draw the text onto the image. Give it a try.
