 # ZKLiveEventBus
 ZKLiveEventBus
+
+## 优先在 Application 注册
+
+如果没跨进程的，可以不用注册
+
+```
+// 请优先注册，最好是 Application 注册
+ZKLiveEventBus.init(this)
+```
+
+## 添加监听消息事件
+
+可以在 Activity 或者 Fragment
+
+```
+ZKLiveEventBus.instance.with(TAG).observe(this, Observer {
+    toast(it)
+})
+
+or
+
+ZKLiveEventBus.instance.with(TAG, String::class.java).observe(this, Observer {
+    toast(it)
+})
+
+```
+
+
+## 发送消息
+
+```
+ZKLiveEventBus.instance.with(TAG).post("测试消息")
+
+or
+
+ZKLiveEventBus.instance.with(TAG).postDelay("测试消息", 1000)
+
+or
+
+ZKLiveEventBus.instance.with(TAG, String::class.java).post("测试消息")
+```
+
+## 参考地址

+https://github.com/JeremyLiao/LiveEventBus
+
+为了方便使用，直接将：LiveEventBus.get() 修改 ZKLiveEventBus.instance 即可。
