An EventBus that support Lifecycle. The Lifecycle-Aware Observers can be auto detached from the EventBus before the Lifecycle is going to destroy.
中文文档(CN)：LifecycleEventBus.md
Any object can be an event
data class LoginEvent(val userId: String)class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
// The observer will be removed when onDestroy
LifecycleEventBus.observe(this, LoginEvent::class.java, object : EventObserver<LoginEvent> {
override fun onEvent(event: LoginEvent) {
// handle event
}
})
}
}class MainActivity : AppCompatActivity() {
private val observer = object : EventObserver<LoginEvent> {
override fun onEvent(event: LoginEvent) {
// handle event
}
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
LifecycleEventBus.observeForever(LoginEvent::class.java, observer)
}
override fun onDestroy() {
super.onDestroy()
LifecycleEventBus.removeObserver(observer)
}
}LifecycleEventBus.sendEvent(LoginEvent("123456789"))The Observer's onEvent() is running on the thread which LifecycleEventBus.sendEvent is invoked by defalut.
You can pass the ThreadMode as a param to observer() or observeForever to specify which thread the observer should run on.
set ThradMode to ThreadMode.MAIN and the observer will run on main thread.
LifecycleEventBus.observe(this, LoginEvent::class.java, observerSubThread, ThreadMode.MAIN)set ThradMode to ThreadMode.ORIGIN and the observer will run on the thread which LifecycleEventBus.sendEvent is invoked. This is the default ThreadMode.
LifecycleEventBus.observe(this, LoginEvent::class.java, observerSubThread)
LifecycleEventBus.observe(this, LoginEvent::class.java, observerSubThread, ThreadMode.ORIGIN)
