Answer 1

Color change:

android:textColor="#FFFFFF"

See color codes here: link

Font (Letter type) change:

android:fontFamily="name of the font family"

See font families here: link

Letter size change:

android:textSize="xxdp"

xx is the size of the font.

You can always refer to this site for guides and documentation: Android dev

Answer 2

if you want change programmatically using java in your onCreateView method inside fragment use:

View view = inflater.inflate(R.layout.YOUR_FRAGMENT_VIEW, container, false);
TextView tv;
tv= findViewById(R.id.textView);
Typeface font;

now if you want change font , first you open a asset folder and inside that add the fontName.ttf in onCreateView method inside your fragment add bellow code:

font = Typeface.createFromAsset(getActivity().getAssets(), "fonts/fontName.ttf ");
tv.setTypeface(font);

if you want change TextView color

tv.setTextColor(Color.RED);

if you want change TextView size

tv.setTextSize(TypedValue.COMPLEX_UNIT_SP,14);
