You can try this

// Load the image
Bitmap originalBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.your_image);

// Define the background color to remove (example: white)
int backgroundColorToRemove = Color.WHITE;

// Create a copy of the original bitmap
Bitmap modifiedBitmap = originalBitmap.copy(Bitmap.Config.ARGB_8888, true);

// Iterate through each pixel
for (int x = 0; x < modifiedBitmap.getWidth(); x++) {
    for (int y = 0; y < modifiedBitmap.getHeight(); y++) {
        int pixelColor = modifiedBitmap.getPixel(x, y);
        if (pixelColor == backgroundColorToRemove) {
            modifiedBitmap.setPixel(x, y, Color.TRANSPARENT); // or set to another color
        }
    }
}

// Set the modified bitmap to an ImageView
imageView.setImageBitmap(modifiedBitmap);

you can either set the background to null (android:background="@null") or use a transparent color (android:background="@android:color/transparent")
