How to obtain image pixel data using BitMap

This article describes the method of Android using BitMap to obtain image pixel data. Share it for your reference, as follows:

The references seen online are:

int[] pixels = new int[()*()];//Save all pixel arrays, picture width × height(pixels,0,(),0,0,(),());
for(int i = 0; i < ; i++){
   int clr = pixels[i];
    int red  = (clr & 0x00ff0000) >> 16; //Take two higher    int green = (clr & 0x0000ff00) >> 8; //Two digits are selected    int blue = clr & 0x000000ff; //Pick the lower two digits    ("r="+red+",g="+green+",b="+blue);
}

The third parameter in getPixels should be the width of the image

There is actually a better function

Bitmap bm = "Get bitmap picture"
(x,y);

Directly obtain pixel point data at x and y coordinates.
