Question

我使用了PullToRefresh chrisBanes lib https://github.com/chrisbanes/Android-PullToRefresh。我扩展了PullToRefreshAttacher，因为我需要特定的行为。所有工作正常，当活动恢复时我有下一个堆栈跟踪错误，但pullToRefresh仍然正常工作（它只在日志中）：

我尝试使用标准的PullToRefresh，我遇到了同样的问题。但是如果我初始化pullToRefresh就像：

ActionBarPullToRefresh.from(this)
        // Mark All Children as pullable
        .allChildrenArePullable()
        // Set a OnRefreshListener
        .listener(...)
        // Finally commit the setup to our PullToRefreshLayout
        .setup(mPullToRefreshLayout);

销毁并恢复后，错误堆栈跟踪未出现。 setup（）方法创建PullToRefreshAttacher并初始化一些其他选项。

这个针对ActionBarPullToRefresh.java@5d84f1b的补丁摆脱了我的堆栈痕迹：
