How to Get Color Form Image programmatical.

 Android- Explain how to get Color code from Image programmatically.

First Set Image in Bitmap :-

final Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap();

Then Get Touch X and Y coordinate from ImageView.

public boolean onTouch(View v, MotionEvent event) {

    x = (int)event.getX();

    y= (int)event.getY();

    return false;

}

Get the color code in Hex String touch on imageView.

Integer.toHexString(bitmap.getPixel(x, y);

Get the color code in Hex String touch on imageView.
