Simple BusProvider.getInstance().post() bring exception not main thread. How to send event from Service to Activity with Otto event bus?

推荐答案

从任何线程（主要还是背景）发布和接收的主线程，尝试像

To post from any thread (main or background) and receive on the main thread, try something like

public class MainThreadBus extends Bus {
  private final Handler mHandler = new Handler(Looper.getMainLooper());

  @Override
  public void post(final Object event) {
    if (Looper.myLooper() == Looper.getMainLooper()) {
      super.post(event);
    } else {
      mHandler.post(new Runnable() {
        @Override
        public void run() {
          MainThreadBus.super.post(event);
        }
      });
    }
  }

注：归功于杰克沃顿商学院和pommedeterresaute在 https://github.com/square/otto/issues / 38 的一般方法。我只是实现它的包装类，而不是一个子类。

Note: credit goes to Jake Wharton and "pommedeterresaute" at https://github.com/square/otto/issues/38 for the general approach. I just implemented it with a wrapper class rather than a subclass.
