There are few options to create custom AlertDialog. I just would like to give you answer for current question. You can set title, message and other components of AlertDialog in onCreate() method. But make sure you doing it before you calling super.onCreate() Example:

public class PausDialog extends AlertDialog {
            @Override
            protected void onCreate(Bundle savedInstanceState) {
                View content = LayoutInflater.from(getContext()).inflate(R.layout.dialog_some_view, null);
                setView(content);
                setTitle("Some Title");
                setMessage("Some Message");
                setButton(DialogInterface.BUTTON_POSITIVE, "Ok", new OnClickListener() {
                   @Override
                   public void onClick(DialogInterface dialog, int which) {
                       Log.d("TAG", "BUTTON_POSITIVE");
                   }
                });
                ((TextView) content.findViewById(R.id.data)).setText(R.string.some_custom_data);
                ((TextView) content.findViewById(R.id.description)).setText(getContext().getString(R.string.description));
                setCancelable(false);
                setOnKeyListener((dialog, keyCode, event) -> keyCode == KeyEvent.KEYCODE_BACK);

                super.onCreate(savedInstanceState);
            }
}
