Answer 1

For full screen dialog you should extend DialogFragment it will provide Fragment life cycle methods and this is the recommended way in Android developer documents you can use simple Dialog or AlertDialog also.

When you create dialog instance just use android.R.style.Theme_Black_NoTitleBar_Fullscreen theme with context like this :

Dialog dialog = new Dialog(getActivity(), android.R.style.Theme_Black_NoTitleBar_Fullscreen);

or

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), android.R.style.Theme_Black_NoTitleBar_Fullscreen);

This will show the dialog in full screen.
