LiveDataBus

Android消息总线，基于LiveData，具有生命周期感知能力

使用方法

依赖

依赖Android Architecture Components，具体可参见gradle文件build.gradle

示例及Demo

订阅消息

  • observe模式 生命周期感知，不需要手动取消订阅
LiveDataBus.get()
	.with("key_name", String.class)
	.observe(this, new Observer<String>() {
	    @Override
	    public void onChanged(@Nullable String s) {
	       
	    }
	});
  • observeForever模式 需要手动取消订阅
LiveDataBus.get()
	.with("key_name", String.class)
	.observeForever(observer);
LiveDataBus.get()
	.with("key_name", String.class)
	.removeObserver(observer);

发送消息

  • set模式 订阅者会在当前线程收到消息
LiveDataBus.get().with("key_name").setValue(value);
  • post模式 订阅者会在主线程收到消息
LiveDataBus.get().with("key_name").postValue(value);

简单的Demo可参见：LiveDataBusDemo.java

原理

LiveDataBus的实现原理可参见作者在美团技术博客上的博文：Android消息总线的演进之路：用LiveDataBus替代RxBus、EventBus
