  Canvas cs = new Canvas(dest);
  Paint tPaint = new Paint();
  tPaint.setTextSize(35);
  tPaint.setColor(Color.BLUE);
  tPaint.setStyle(Style.FILL);
  cs.drawBitmap(src, 0f, 0f, null);
  float height = tPaint.measureText("yY");
  cs.drawText(dateTime, 20f, height+15f, tPaint);
  try {
      dest.compress(Bitmap.CompressFormat.JPEG, 100, new FileOutputStream(new File("/sdcard/timeStampedImage.jpg")));
  } catch (FileNotFoundException e) {

If you're asking how to simply display something on top of your video, the answer is sure... just use a relative layout and put your TextView in the same coordinates as the SurfaceView you're using for your Camera preview... as long as it is after the SurfaceView in the XML it will draw on top of it.

Or if you insist on drawing your text to Canvas, put your drawing surface view on top of the Camera preview. Either way, as long as it's added to the parent view after the Cam surface it will draw on top of it.
