How to programmatically create simple image with text inside?

Question

I need to create simple image in my application programmatically. Simple image will have black background with text inside which is created programmatically. Is it possible?

Can you elabore more on the question? For what do you want this image? Why won't/can't you use the built-in android ViewWidgets to do this? — josephus, Nov 06 '11 at 08:48

    int width = 200;
    int height = 100;
    Bitmap bitmap = Bitmap.createBitmap(width, height, Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);

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

    paint.setColor(Color.WHITE);
    paint.setAntiAlias(true);
    paint.setTextSize(14.f);
    paint.setTextAlign(Paint.Align.CENTER);
    canvas.drawText("Hello Android!", (width / 2.f) , (height / 2.f), paint);

And then do whatever you wanted to do with the Bitmap. For example:

ImageView image = new ImageView();
image.setImageBitmap(bitmap);

`Config.ARGB_8888` can be `Bitmap.Config.ARGB_8888` if it throws an error. — emc, Jan 13 '17 at 19:05

This depends very much on your implementation details (Java SE? Android? Restricted imports? etc)

I suggest you take a look at this StackOverflow question and see if any of the libraries linked are right for your situation.

Oh, I didn't see the tag, sorry. I'm not very familiar with Android, but I recommend you still take a look at the question I linked; you may be able to user one of the libraries. – Deco Nov 06 '11 at 08:32
