这个ANR是什么意思？

时间：2014-04-03 02:18:58

标签： java android android-listview android-anr-dialog

我已启用StrictMode并捕获此日志（/data/anr/traces.txt）。问题是列表视图在处理大约3行（第4行）后挂起。我正在使用持有人模式。其他地方的列表视图似乎工作正常。

感谢任何帮助。

发现问题。 堆栈跟踪提供了一些线索alignBase（）。发生的事情是对齐是基于一个不可见并引用自己的小部件。所以主线程进入挂起状态。

即。申请没有回应......

如果您在主（UI）线程上尝试执行需要很长时间（例如从远程服务器下载映像/数据）的任务，则会发生此ANR

要摆脱这种尝试，请为这些长时间运行的任务使用asyntask / thread。

答案 1 :(得分：0)

发现问题。堆栈跟踪提供了一些线索，alignBase（）调用。发生的事情是，对齐是基于一个不可见并引用自己的小部件（评级栏）。所以主线程进入挂起状态。

Stacktrace非常有用，一旦你知道如何阅读它，它的全部内容都是追溯到你的代码中调用的位置。在我的情况下，它涉及很少，因为所涉及的所有类都是android。
