lifecycle @onlifecycleevent（）已弃用，您应该使用LifeCycleEventObserver或DefaultLifeCycleObServer

Question

答案在底部，

我认为这对您有用

Answer 1

1- LifeCycleVentObserver

首先

您应该实现以下操作：

”旧的依赖性已被弃用：

implementation "androidx.lifecycle:lifecycle-extensions:2.2.0"

新的依赖性，您应该使用此

dependencies {    
    implementation"androidx.lifecycle:lifecycleprocess:2.8.3"
}

其次

应该写这件：

class App : Application() {
    override fun onCreate() {
        super.onCreate()

        ProcessLifecycleOwner.get().lifecycle.addObserver(lifecycleEventObserver)

    }

第三，

您应该写下：

在这里，我仅实施了两个生命周期事件，当您需要其他生命周期事件时，您应该实现它们

    var lifecycleEventObserver = LifecycleEventObserver { _, event ->
        when (event) {
            Lifecycle.Event.ON_STOP -> {
                //your code here
            }
            Lifecycle.Event.ON_START -> {
                //your code here
            }
            else -> {}
        }
    }

2- defaultlifecycleobserver，

首先

您应该实现此处：

dependencies {
    implementation "androidx.lifecycle:lifecycle-extensions:2.2.0"
}

其次，

您应该写下：

class App : Application() {
    override fun onCreate() {
        super.onCreate()

        ProcessLifecycleOwner.get().lifecycle.addObserver(defaultLifecycleObserver)

    }

第三，

您应该写下：

在这里，我仅实施了两个生命周期事件，当您需要其他生命周期事件时，您应该实现它们

    var defaultLifecycleObserver = object : DefaultLifecycleObserver {

        override fun onStart(owner: LifecycleOwner) {
            super.onStart(owner)
            //your code here
        }

        override fun onStop(owner: LifecycleOwner) {
            super.onStop(owner)
            //your code here
        }
    }

3-活动lifecyClecallbacks，

首先

您应该写下：

class App : Application() {
    override fun onCreate() {
        super.onCreate()

        registerActivityLifecycleCallbacks(activityLifecycleCallbacks)

    }

其次，

您应该写这篇文章：

    private val activityLifecycleCallbacks = object : ActivityLifecycleCallbacks {
        
        override fun onActivityCreated(activity: Activity, savedInstanceState: Bundle?) {
            
        }

        override fun onActivityStarted(activity: Activity) {
            
        }

        override fun onActivityResumed(activity: Activity) {
            
        }

        override fun onActivityPaused(activity: Activity) {
           
        }

        override fun onActivityStopped(activity: Activity) {
            
        }

        override fun onActivitySaveInstanceState(activity: Activity, outState: Bundle) {

        }

        override fun onActivityDestroyed(activity: Activity) {

        }

    }
