java - Java中线程优先级到底是做什么的

Question

这个问题已经有答案了:

Java multithreading - thread priority (6 个回答)

已关闭 6 年前。

我目前正在开发一个用java编写的android项目。我有一个仪表板，可以从 cloudant 数据库查询数据并将数据呈现在图表上。然而，数据必须在收到后进行处理。
我有 4 个 AsyncTasks，它们同时(或应该)处理 doInBackground Override 方法中接收到的数据。过程非常慢，我尝试了该行

Thread.currentThread().setPriority(Thread.MAX_PRIORITY);

在每个 AsyncTask 中。
然而，4个AsynkTasks似乎都相继发生，这是由于将线程优先级更改为max所致吗？当线程优先级更改时，它是否会停止所有其他线程并仅继续处理该线程直到完成？

Every thread has a priority. Threads with higher priority are executed in preference to threads with lower priority. Each thread may or may not also be marked as a daemon. When code running in some thread creates a new Thread object, the new thread has its priority initially set equal to the priority of the creating thread, and is a daemon thread if and only if the creating thread is a daemon.

(注意:此信息是通过在 Google 中搜索“java Thread.MAX_PRIORITY”并查看顶部结果找到的)
