How to change color of status bar dynamically in android based upon the foreground image?

Question

I want to implement the same feature as we can see in WhatsApp, while seeing a person's profile the color of the status bar changes based upon the color of the image.

Whats Whatsapp? I don't have it on my iphone. How I am supposed to verify the situation you are describing? This is the reason you should clearly mention what you want now say like "I want what XYZ does". — Rohit5k2, May 10 '19 at 10:47

It's called Pallete, use the below function, just pass your bitmap image

  private void setUpPalette(Bitmap bitmap) {
   // you passed your Bitmap image;
    Palette.from(bitmap).
            generate(new Palette.PaletteAsyncListener() {
                @Override
                public void onGenerated(Palette palette) {
                    if (palette != null) {

                       //default color is yellow
                       // set the color to toolbar, whatever
                        int extColor = palette.getVibrantColor(ContextCompat.getColor(MainActivity.this, R.color.yellow));
                         if (getWindow() != null) {
                                getWindow().setStatusBarColor(ContextCompat.getColor(this, extColor));
                                }
                    } else {
                         if (getWindow() != null) {
                                    getWindow().setStatusBarColor(ContextCompat.getColor(this, R.color.fail_safe));
                                                    }
                    }
                }
            });
}

extcolor is int but getcolor method required id of the resource, hence it is giving me error — TheSohan, May 10 '19 at 11:25
ContextCompat.getColor(context , id), first param is the context and second is id — hemen, May 10 '19 at 11:42

You have to use the Palette library to get the dominant color:

// Generate palette asynchronously and use it on a different
// thread using onGenerated()
public void changeStatusBarColorAsync(Bitmap bitmap) {
  Palette.from(bitmap).generate(new PaletteAsyncListener() {
    public void onGenerated(Palette p) {
      // Use generated instance
      Palette.Swatch vibrant = p.getVibrantSwatch();
      int color = ContextCompat.getColor(getContext(),R.color.default_title_background);
      if(vibrant != null){
        color = vibrantSwatch.getTitleTextColor();
      }
      getWindow().setStatusBarColor(ContextCompat.getColor(this, color));
    }


  });
}

https://stackoverflow.com/a/28145358/9186913 you will find the most vibrant color in the image and you can change the getWindow().setStatusBarColor(getResources().getColor(R.color.color));
