滑动返回后应用崩溃,该界面里有SwipeMenuRecyclerView

[zhucidong]

SwipeMenuRecyclerView是在 compile 'com.yanzhenjie:recyclerview-swipe:1.1.3' 包下面的

/**

• 必须在 Application 的 onCreate 方法中执行 BGASwipeBackHelper.init 来初始化滑动返回
• 第一个参数：应用程序上下文
• 第二个参数：如果发现滑动返回后立即触摸界面时应用崩溃，请把该界面里比较特殊的 View 的 class 添加到该集合中，目前在库中已经添加了 WebView 和 SurfaceView */ List<Class<? extends View>> l = new ArrayList<>(); l.add(SwipeMenuRecyclerView.class); BGASwipeBackHelper.init(this, l);

添加之后还是崩溃

反馈问题时请提供当前使用开源库具体版本号、报错手机型号、报错手机系统版本以及错误日志

用的是 compile 'cn.bingoogolapple:bga-swipebacklayout:1.1.5' 任何机型都是一样的报错 报错重现的方式如下： 将代码中recyclerview替换成compile 'com.yanzhenjie:recyclerview-swipe:1.1.3' 包下面的SwipeMenuRecyclerView 此SwipeMenuRecyclerView是继承自recyclerview的 点击SwipeMenuRecyclerView（列表）中的一个item 跳转到B（详情）页面 然后左滑详情页面，返回到列表页，就会报错，如果是点击手机返回键则不会报错。 报错信息如下：

这个问题根源可能是对前面一个Activity的rootView做了remove、add操作引起的

[zhucidong]

没有remove、add等操作 就是个很普通的详情页面，只要侧滑，露出之前的列表页面就会报错。 如果之前的不是列表页面，则一切正常 根源问题：只要是从带有SwipeMenuRecyclerView的页面跳转到其他页面，然后通过侧滑返回就会报错 报错内容上面已经发过了

[xiaobaDev]

不是你业务层做的remove、add操作；是咱底层的侧滑事件里面，会把前一个Activity的rootView加到当前的Activity
