代码

Menifest:

<activity android:name=".cycle.MainLifeActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>
</activity>
<activity android:name=".cycle.DialogLifeActivity" android:theme="@style/Theme.AppCompat.Dialog"/>
<activity android:name=".cycle.NormalLifeActivity"/>

Kotlin:

MainLIfeActivity:

class MainLifeActivity : AppCompatActivity() {
    private val tag = "MainLife"

    private lateinit var mainBinding: ActivityLifeMainBinding
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        Log.d(tag,"onCreate")
        mainBinding = ActivityLifeMainBinding.inflate(layoutInflater)
        setContentView(mainBinding.root)

        mainBinding.mainStartNormal.setOnClickListener {
            val intent = Intent(this, NormalLifeActivity::class.java)
            startActivity(intent)
        }
        mainBinding.mainStartDialog.setOnClickListener {
            val intent = Intent(this, DialogLifeActivity::class.java)
            startActivity(intent)
        }
    }

    override fun onStart() {
       super.onStart()
       Log.d(tag,"onStart")
   }

   override fun onStop() {
       super.onStop()
       Log.d(tag,"onStop")
   }

   override fun onDestroy() {
       super.onDestroy()
       Log.d(tag,"onDestroy")
   }

   override fun onResume() {
       super.onResume()
       Log.d(tag,"onResume")
   }

   override fun onPause() {
       super.onPause()
       Log.d(tag,"onPause")
   }

   override fun onRestart() {
       super.onRestart()
       Log.d(tag,"onRestart")
   }
}

NormalLifeActivity,DialogLifeActivity:

class NormalLifeActivity: AppCompatActivity() {
    private lateinit var normalBinding: ActivityLifeNormalBinding
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        normalBinding= ActivityLifeNormalBinding.inflate(layoutInflater)
        setContentView(normalBinding.root)
    }
}

class DialogLifeActivity: AppCompatActivity() {

    private lateinit var dialogBinding: ActivityLifeDialogBinding
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        dialogBinding= ActivityLifeDialogBinding.inflate(layoutInflater)
        setContentView(dialogBinding.root)
    }
