我需要帮助!!!请!!
答案
当您尝试从无法执行的线程更新视图时，可能会出现此错误。 new Thread()类创建一个不同的线程，因此android主线程不允许从主线程以外的其他线程更新UI。您需要使用runOnUiThread来更新您的视图。
您可以使用runOnUiThread，如下所示：
runOnUiThread(new Runnable()
public void run()
// your code to update the UI thread here
);
以上是关于java.lang.NoSuchMethodError E / AndroidRuntime：FATAL EXCEPTION：Thread-4进程：com.hikvision.open.app，PID的主要内容，如果未能解决你的问题，请参考以下文章
