只是不要在UI线程上运行很长时间（或者某些情况下可能很长的事情）。
这包括：数据库操作，互联网操作，复杂计算，大型存储操作（如编写大文件），......
每个操作都可以在asyncTask，新线程，带线程的服务，intentService，syncAdapter，线程池等运行......
操作完成后，您可以使用Handler对象告诉UI所有内容已完成。
答案 1 :(得分：0)
通常，如果应用程序无法响应用户输入，则会发生ANR。最常见的情况是在主UI线程中执行一些升沉任务。这些任务会阻碍工作流程，从而产生ANR。
要解决此问题，您应该使用不同的线程而不是UI线程来执行繁重的任务。您可以使用不同的工作线程，AsyncTask或将Runnable发布到处理程序来执行任务。

ANR可能由以下原因引起：
首先在您的日志中搜索'timeout'关键字，然后我才能帮助您
