First you need to know that handling of full screen in Dialog fragment is different from the normal Dialog component, second you need to customize the Dialog fragment before the actual creation of the dialog @ (OnCreateDialog), according to the answer of "user3244180" Full screen DialogFragment

 @Override
 public Dialog onCreateDialog(final Bundle savedInstanceState) {

     // the content
     final RelativeLayout root = new RelativeLayout(getActivity());
     root.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

     // creating the fullscreen dialog
     final Dialog dialog = new Dialog(getActivity());
     dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
     dialog.setContentView(root);
     dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
     dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

     return dialog;
 }
