canvas.drawARGB(0, 0, 0, 0)

This line will draw a canvas of black color. If you just want to change the color, change the rgb values. For e.g

canvas.drawARGB(255, 0, 0, 0)

will draw a red color bitmap canvas.

The first one actually draws nothing because you're using ARGB meaning you're setting alpha to 0 – Nathan Bird Dec 21 '18 at 14:51

ImageView imageView = (ImageView) findViewById(imageViewId);

// Set the background for the ImageView
imageView.setBackgroundResource(R.drawable.yourdrawableImage);

// set background color
backgroundImg.setBackgroundColor(Color.parseColor("#FFFFFF"));

setBackgroundColor(Color.rgb(100, 100, 50));

Or else change the background color of parent layout.
