Firebase数据库-在不同的线程上运行 [英] Firebase database - run on different thread

问题描述

我想在其他线程上运行firebase事件.在Firebase的最新版本中，我有执行此代码的代码

I want to run the events of firebase on different thread. On the last version of firebase I had this code that did it

    Config firebaseConfig = new Config();
    firebaseConfig.setEventTarget(new EventTarget() {
        ExecutorService executor = Executors.newSingleThreadExecutor();
        @Override
        public void postEvent(Runnable runnable) {
            executor.execute(runnable);
        }

        @Override
        public void shutdown() {
            executor.shutdown();
        }

        @Override
        public void restart() {

        }
    });
    Firebase.setDefaultConfig(firebaseConfig);

如何在新的api中做到这一点?他们是一种方式还是我必须自己实现? (创建每个函数的runnable并在执行程序中运行它)

How can I do it in the new api? Their is a way or I have to implement it by my self? (create runnable of every function and run it in the executor)

推荐答案

Firebase数据库客户端在单独的线程上执行所有网络，磁盘I/O和其他维护.然后，它会在主线程上显示对代码的回调，以便您可以与UI进行交互.

The Firebase Database client performs all networking, disk I/O and other maintenance on a separate thread. It then surfaces the callbacks to your code on the main thread, so that you can interact with the UI.

在大多数情况下，您无需执行任何特殊操作，只需让Firebase客户端处理跨线程处理即可.仅当您需要在回调中做一些繁重的工作(例如onDataChange())时，才需要再次在主线程上运行该工作.您可以为此使用通常的Android线程机制.

In most situations you don't have to do anything special and can just let the Firebase client deal with the cross-threading handling. Only when you need to do some heavy work in your callback (e.g. onDataChange()) will you have to run that work off the main thread again. You can use the usual Android threading mechanisms for that.
