Android: Can we create bitmaps with Strings on it on the application runtime?

Question

I want to create a Bitmap with some string data on it, and later send it to my mobile printer.

How can we do that?

try like this:

Bitmap resultBitmap = Bitmap.createBitmap(100, 100, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(resultBitmap);
Paint paint = new Paint();
paint.setColor(Color.RED);
canvas.drawText("", 10, 10, paint);
//here you can return that bitmap directly

It worked but the background of the image is black (since the printer is white and black only). Can we set it to white? – Muayad Salah Apr 29 '15 at 06:58

Call `canvas.drawColor(Color.WHITE);` before calling `canvas.drawText(...);`. – Bartek Lipinski Apr 29 '15 at 07:08
