Canvas keep ignoring Paint in drawBitmap method

I would like to draw bitmap(with specified color) on canvas.

    Paint paint = new Paint();
    paint.setAntiAlias(true);
    paint.setStyle(Paint.Style.FILL);
    paint.setColor(Color.RED);

// create bitmap

    canvas.drawBitmap(bitmap, 0, 0, paint);

Well, the bitmap is visible on the canvas, but color of drawable didn't change. Where is the problem?

paint.setColor(Color.RED) is irrelevant. If your image comes with an alpha channel and you want it to be drawn in a single color, use ColorFilter instead:

paint.setColorFilter(new PorterDuffColorFilter(Color.RED, PorterDuff.Mode.SRC_IN);

A bitmap contains an image and drawing an image in single color doesn't make any sense. What do you expect it to do? Draw a red rectangle? Shapes can be drawn with color, not images...

The Color attribute of your Paint will be ignored. That Paint parameter is used to pass other settings such as anti-aliasing.

I hope this clarifies.
