  • Palette palette = Palette.generate(bitmap); int default = 0x000000; int vibrant = palette.getVibrantColor(default); int vibrantLight = palette.getLightVibrantColor(default); int vibrantDark = palette.getDarkVibrantColor(default); int muted = palette.getMutedColor(default); int mutedLight = palette.getLightMutedColor(default); int mutedDark = palette.getDarkMutedColor(default); – Tarang Acharya Dec 08 '17 at 07:20

Use this code for getting colors from images. You can follow this tutorial for further information.

https://medium.com/david-developer/extracting-colors-from-images-integrating-picasso-and-palette-b9ba45c9c418

 Palette.from(bitmap)
            .generate(new Palette.PaletteAsyncListener() {
                @Override
                public void onGenerated(Palette palette) {
                    Palette.Swatch textSwatch = palette.getVibrantSwatch();
                    if (textSwatch == null) {
                        Toast.makeText(MainActivity.this, "Null swatch :(", Toast.LENGTH_SHORT).show();
                        return;
                }
                backgroundGroup.setBackgroundColor(textSwatch.getRgb());
                titleColorText.setTextColor(textSwatch.getTitleTextColor());
                bodyColorText.setTextColor(textSwatch.getBodyTextColor());
            }
        });

Use this

Matrix inverse = new Matrix();
                    v.getMatrix().invert(inverse);
                    float[] touchPoint = new float[] {event.getX(), event.getY()};
                    inverse.mapPoints(touchPoint);
                    int xCoord = (int) touchPoint[0];
                    int yCoord = (int) touchPoint[1];
                    int intColor = ((BitmapDrawable)imageView.getDrawable()).getBitmap().getPixel(xCoord,yCoord);


btn.setBackgroundColor(intColor);

Hope This will help

OR

Simply Change this in you code, don't convert the color pixel to hex. Use the color pixel directly in setBackGroundColor(pixel) like 

btn.setBackgroundColor(pixel);

This is the full code i have tried

imageView.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {

        if (event.getAction()==(MotionEvent.ACTION_DOWN)){

            Matrix inverse = new Matrix();
            v.getMatrix().invert(inverse);
            float[] touchPoint = new float[] {event.getX(), event.getY()};
            inverse.mapPoints(touchPoint);
            int xCoord = (int) touchPoint[0];
            int yCoord = (int) touchPoint[1];
            int intColor = ((BitmapDrawable)imageView.getDrawable()).getBitmap().getPixel(xCoord ,yCoord );


            try {
                btn.setBackgroundColor(intColor);
            }catch (Exception e){
                e.printStackTrace();
            }

            return false;
        }
        return false;
    }
});

Try catch is not necessary but i am putting it only for precaution for any unplanned error
