PullToRefresh(chrisbanes lib) 窗口泄露

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。一切正常，当活动恢复时我有下一个堆栈跟踪错误，但 pullToRefresh 仍然可以正常工作（它只在日志中）：

我尝试使用标准的 PullToRefresh，但遇到了同样的问题。 但如果我像这样初始化 pullToRefresh：

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

销毁和恢复后，没有出现错误堆栈跟踪。 setup() 方法创建 PullToRefreshAttacher 并初始化一些附加选项。

这个针对ActionBarPullToRefresh.java@5d84f1b 的补丁为我消除了堆栈跟踪：
