Define your events\n```kotlin\n// With data\ndata class ShowMessageEvent(val message: String)\n\n// Without data\nclass OtherEvent\n```\n\n### 2. Add subscribers\n```kotlin\noverride fun onStart() {\n    super.onStart()\n    KBus.subscribe\u003cShowMessageEvent\u003e(this) {\n        showMessage(it.message)\n    }\n    KBus.subscribe\u003cOtherEvent\u003e(this) {\n        doSomething()\n    }\n}\n\noverride fun onStop() {\n    super.onStop()\n    KBus.unsubscribe(this)\n}\n```\n\nWhere:\n* **ShowMessageEvent** - the event you're subscribing\n* **this** - the subscriber (by default the current Activity/Fragment)\n* **{ showMessage() }** - the subscription observer\n* **it** - the event instance\n\n#### Sticky events\nIf you want to post events between Activities/Fragments just subscribe in `onCreate()` (or `onPostCreate()`) and unsubscribe in `onDestroy()`\n```kotlin\noverride fun onPostCreate(savedInstanceState: Bundle?) {\n    super.onPostCreate(savedInstanceState)\n    KBus.subscribe\u003cShowMessageEvent\u003e(this) {\n        showMessage(it.message)\n    }\n}\n\noverride fun onDestroy() {\n    super.onDestroy()\n    KBus.unsubscribe(this)\n}\n```\n\n### 3. Post events\n```kotlin\nKBus.post(ShowMessageEvent(\"Hello KBus!\"))\n```\n\n## Add KBus to your project\n```gradle\nrepositories {\n    maven { url \"https://jitpack.io\" }\n}\n\ndependencies {\n    implementation 'io.reactivex.rxjava2:rxjava:2.2.10'\n    implementation 'com.github.adrielcafe:KBus:1.1'\n}\n```","funding_links":["https://ko-fi.com/adrielcafe"],"categories":["Libraries","进程间通信"],"sub_categories":["Spring Cloud框架"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fadrielcafe%2FKBus","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fadrielcafe%2FKBus","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fadrielcafe%2FKBus/lists"}
