Answer 1

mTextView.setTextColor(Color.parseColor("#bdbdbd"));  

Or if you have defined color code in resource's color.xml file than

(From API >= 23)

mTextView.setTextColor(ContextCompat.getColor(context, R.color.<name_of_color>));

(For API < 23)

mTextView.setTextColor(getResources().getColor(R.color.<name_of_color>));
