How do you get the RGB values from a Bitmap on an Android device?

Question

I want to get RGB values of bitmap in android but I cant do this so far. My aim is to obtain RGB values for each pixel of bitmap. Is there any specific function for android

Answer 1

Bitmap.getPixel(x, y) returns an int with the colour values and alpha value embedded into it.

int colour = bitmap.getPixel(x, y);

int red = Color.red(colour);
int blue = Color.blue(colour);
int green = Color.green(colour);
int alpha = Color.alpha(colour);
