                    app:font="@{@string/font_roboto_regular}" />
            </RelativeLayout>

        </ScrollView>

    </LinearLayout>

    <ProgressBar
    android:id="@id/progressBar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:visibility="visible"/>
</RelativeLayout>

我的 dialogFragment 像这样

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();
        }
    };
}

这里我需要显示进度条，比如调用 mBinding.progressBar.setVisibility(View.VISIBLE); 但它不允许调用这个。任何调用进度条的建议

我认为id声明问题

改变

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

并尝试
