You will need to get the dominant color from the image you are using then create a gradient drawable between a starting color and your dominant color. There are multiple ways to find dominant colors which you can read up on here: Finding the dominant color of an image in an Android @drawable

From there you create a drawable and set the background of your view to that drawable:

    // get the drawable from the image view
    // could also be pulled from resources if available
    Bitmap bm=((BitmapDrawable)imageView.getDrawable()).getBitmap();

    int color = getDominantColor(bm);

    GradientDrawable gradient = new GradientDrawable(
            GradientDrawable.Orientation.TOP_BOTTOM,
            new int[] {0xFFF,color});
    gradient.setCornerRadius(15f);

    contentView.setBackground(gradient);
