Android – draw text on bitmap

I'm trying to put text on the map marker, but it always appears below it. First, I convert drawable to bitmap, and then draw text on it. The conversion effect from drawable to bitmap is very good. I only have the problem of text coverage

I've tried these:

There are more unlucky ones

This is my current approach:

Bitmap drawableToBitmap(Drawable drawable)
    {
        var bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
        var canvas = new Canvas(bitmap);
        if (shouldDrawText)
        {
            Paint paint = new Paint();
            paint.setColor(Color.WHITE);
            paint.setstrokeWidth(40);
            paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_OVER)); // Text Overlapping Pattern

            //canvas.drawBitmap(bitmap, 0, 0, paint);
            canvas.drawText("Testing...", 10, 10, paint);
        }
        drawable.SetBounds(0, 0, canvas.Width, canvas.Height);
        drawable.Draw(canvas);
        return bitmap;
    }

What do you think I did wrong?

resolvent:

paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_OVER)); // Text Overlapping Pattern

Here, you use Src_ Over, which means that the source will be below the DST. DST is the new pixel to be drawn

You should use DST_ Over draws a new pixel over the old one

paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DST_OVER)); // Text Overlapping Pattern

Here's an overview of how porterduff works
