Android切换主题生命周期流程与onSaveInstanceState和onRestoreInstanceState，Kotlin

import android.os.Bundle
import android.util.Log
import androidx.appcompat.app.AppCompatActivityclass MainActivity : AppCompatActivity() {private val TAG = "fly"private val KEY = "my_key"private var mBundle: Bundle? = nulloverride fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)Log.d(TAG, "onCreate")}override fun onSaveInstanceState(outState: Bundle) {super.onSaveInstanceState(outState)val t = System.currentTimeMillis()outState.putString(KEY, t.toString())Log.d(TAG, "onSaveInstanceState ${t}")}override fun onRestoreInstanceState(savedInstanceState: Bundle) {super.onRestoreInstanceState(savedInstanceState)mBundle = savedInstanceStateLog.d(TAG, "onRestoreInstanceState ${savedInstanceState.getString(KEY)}")}override fun onResume() {super.onResume()Log.d(TAG, "onResume ${mBundle?.getString(KEY)}")}override fun onRestart() {super.onRestart()Log.d(TAG, "onRestart")}override fun onStart() {super.onStart()Log.d(TAG, "onStart")}override fun onPause() {super.onPause()Log.d(TAG, "onPause")}override fun onStop() {super.onStop()Log.d(TAG, "onStop")}override fun onDestroy() {super.onDestroy()Log.d(TAG, "onDestroy")}
}

App启动后，把状态栏下滑出来，点击切换深色主题/暗色模式后的生命周期：
