Meine dialogFragment wie diese

public class PopupInviteConsumerDialog extends BaseDialog implements View.OnClickListener { 
private InviteConsumerDialogBinding mBinding; 
private Context mContext; 

public static PopupInviteConsumerDialog newInstance(Context context) { 
    PopupInviteConsumerDialog dialog = new PopupInviteConsumerDialog(); 
    dialog.mContext = context; 
    return dialog; 
} 

@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
    super.onCreateView(inflater, container, savedInstanceState); 

    getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE); 
    getDialog().getWindow().setBackgroundDrawableResource(android.R.color.transparent); 

    mBinding = DataBindingUtil.inflate(inflater, R.layout.invite_consumer_dialog, container, false); 

    setCancelable(false); 
mBinding.progressBar.setVisibility(View.VISIBLE); 
    mBinding.submit.setOnClickListener(this); 

    return mBinding.getRoot(); 
} 

@Override 
public void onStart() { 
    super.onStart(); 
    getDialog().getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT); 
} 

@Override 
public void onClick(View view) { 
    switch (view.getId()) { 
     case R.id.submit: 
      submit(); 
      break; 
    } 
} 

@Override 
public Dialog onCreateDialog(@NonNull Bundle savedInstanceState) { 
    return new Dialog(getActivity(), getTheme()) { 
     @Override 
     public void onBackPressed() { 
      dismiss(); 
     } 
    }; 
} 

Hier Ich brauche die progressbar zu zeigen, wie Aufruf mBinding.progressBar .setVisibility (View.VISIBLE); Aber es wird nicht erlauben, dies zu nennen. Jeder Vorschlag, der ProgressBar zu nennen

Ich denke Problem id Erklärung

Änderung

android: id = "@ id/progressBar" zu android: id = "@ + id/progressBar "

und versuchen
