我关闭了开发者选项的所有动画.但是当我尝试点击其中一个按钮时,我仍然会遇到此异常.

Answer 1

过去几天我一直在为这个问题苦苦挣扎。
这是我用来识别“违规者”的方法：

private void dumpThreads() {
    int activeCount = Thread.activeCount();
    Thread[] threads = new Thread[activeCount];
    Thread.enumerate(threads);
    for (Thread thread : threads) {
        System.err.println(thread.getName() + ": " + thread.getState());
        for (StackTraceElement stackTraceElement : thread.getStackTrace()) {
            System.err.println("\t" + stackTraceElement);
        }
    }
}

就我而言，Facebook SDK 使用 AsyncTask 线程池。

这是我的应用程序代码中的一个错误，SwipeRefreshLayout它本身会无限期地进行动画处理。由于此组件中存在错误，\n 甚至未显示刷新状态。
