Dynamically change SVG image color in android

Question

I know that using third party library, it is possible to use SVG image in Android. Library like: svg-android

The code to load SVG image is like below:

 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Create a new ImageView
    ImageView imageView = new ImageView(this);
    // Set the background color to white
    imageView.setBackgroundColor(Color.WHITE);
    // Parse the SVG file from the resource
    SVG svg = SVGParser.getSVGFromResource(getResources(), R.raw.android);
    // Get a drawable from the parsed SVG and set it as the drawable for the ImageView
    imageView.setImageDrawable(svg.createPictureDrawable());
    // Set the ImageView as the content view for the Activity
    setContentView(imageView);
}

It's working fine. I'm able to see the image. But now I want to change the color for the svg image at runtime. For that I tried the code below as mentioned in the same project description.

  // 0xFF9FBF3B is the hex code for the existing Android green, 0xFF1756c9 is the new blue color
    SVG svg = SVGParser.getSVGFromResource(getResources(), R.raw.android, 0xFF9FBF3B, 0xFF1756c9);

But with that I am not able to see the change in the color. So I would like to know how it is possible to change the color dynamically in Java file.

I got where is the problem. The issue is with the color code i am using in svg file. Its not exactly 0xFF9FBF3B but #9FBF3B
But during java code you have to write it with ARGB value (e.g. 0xFF9FBF3B). I have updated it and its work fine now. I can able to change the color of svg file with same code.

Hope this will also help others to identify the actual case while changing the color of the SVG image at runtime.
