本文整理了Java中androidx.lifecycle.Lifecycle.addObserver()方法的一些代码示例，展示了Lifecycle.addObserver()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Lifecycle.addObserver()方法的具体详情如下：
包路径：androidx.lifecycle.Lifecycle
类名称：Lifecycle
方法名：addObserver

Lifecycle.addObserver介绍

[英]Adds a LifecycleObserver that will be notified when the LifecycleOwner changes state.

The given observer will be brought to the current state of the LifecycleOwner. For example, if the LifecycleOwner is in State#STARTED state, the given observer will receive Event#ON_CREATE, Event#ON_START events.
[中]添加LifecycleOwner更改状态时将收到通知的LifecycleObserver。
给定的观察者将处于LifecycleOwner的当前状态。例如，如果LifecycleOwner处于“已启动”状态，则给定的观察者将接收事件“正在创建”，事件“正在启动”。
