Answer 1

I want clarify this. Both the ways are right, But with different DialogFragment.

Using android.app.DialogFragment

@Override
public void onStart()
{
    super.onStart();
    Dialog dialog = getDialog();
    if (dialog != null)
    {
        int width = ViewGroup.LayoutParams.MATCH_PARENT;
        int height = ViewGroup.LayoutParams.MATCH_PARENT;
        dialog.getWindow().setLayout(width, height);
    }
}

Using android.support.v4.app.DialogFragment

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme_Black_NoTitleBar_Fullscreen);
}
