From the answer @CornflakesDK and @ice spirit, I thought you can use the current AlertDialog.Builder implementation to do the custom dialog and make it easy to maintain.

CustomDialogBuilder.java

public class CustomDialogBuilder extends AlertDialog.Builder {

  private View view;

  public CustomDialogBuilder(Context context) {
    super(context);
    view = LayoutInflater.from(getContext()).inflate(R.layout.custom_dialog_title, null);
    setCustomTitle(view);
  }

  @Override
  public Builder setTitle(int titleId) {
    TextView titleTextView = view.findViewById(R.id.exemptionSubHeading4);
    titleTextView.setText(getContext().getString(titleId));
    return this;
  }

  @Override
  public Builder setTitle(CharSequence title) {
    TextView titleTextView = view.findViewById(R.id.exemptionSubHeading4);
    titleTextView.setText(title);
    return this;
  }
}

custom_dialog.xml

Inside your activity code,

 new CustomDialogBuilder(MyActivity.this)
                  .setTitle(R.string.actions)
                  .setItems(R.array.items_actions, (dialog, which) -> {
                    // handle items
                  }).create().show();

Then, you can have styling inside the DialogBuilder and also utilize the functions of the AlertDialog.Builder.
