android - 无法膨胀行为子类 com.luseen.spacenavigation.SpaceNavigationViewBehavior

Question

在我的应用程序中，我包含了这个库 https://github.com/armcha/Space-Navigation-View用于底部导航和添加回收器 View 滚动行为

<com.luseen.spacenavigation.SpaceNavigationView
        android:id="@+id/space"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        app:space_background_color="@color/colorPrimary"
        app:active_item_color="@color/colorTextPrimary"
        app:inactive_item_color="@color/colorWhite"
        app:centre_button_color="@color/colorAccent"
        app:centre_button_icon="@drawable/ic_camera_white_24dp"
        app:inactive_centre_button_icon_color="@color/colorWhite"
     app:layout_behavior="com.luseen.spacenavigation.SpaceNavigationViewBehavior" />

我在 gradle 文件中启用了 mutidex。没有为库添加 progaurd 规则。他们没有提到要包括的内容。现在这在 Debug模式下工作正常。在 Release模式下，这会失败并出现以下错误

我有解决方案:-

    public class SpaceNavigationViewBehavior<V extends View> extends CoordinatorLayout.Behavior<V> {

        public SpaceNavigationViewBehavior(Context context, AttributeSet attrs) {
            super();
        }

        public SpaceNavigationViewBehavior() {
            super();

        @Override

            return dependency instanceof Snackbar.SnackbarLayout;
        }

        @Override

        }

        @Override

            } else if (dyConsumed < 0) {
                Utils.makeTranslationYAnimation(child, 0);
            }
        }
    }
