    Thanks,
    please consider to change the code below as it is consuming a lot of resources :

    Instead of this in the loop:
    for loop
    getResources().getColor(R.color.black):getResources().getColor(R.color.white);

    do this:
    int bgColor = getResources().getColor(R.color.black);
    int color = getResources().getColor(R.color.white);

    for loop
    bgColor:color;
