AndroidStudio（Kotlin）的导航问题

Question

我想寻求帮助，我正面临问题，我不知道如何解决。我在5秒钟后设计了一个启动屏幕，应该导航到另一个活动，我的问题是，如果在导航至第二个活动的过程中按了启动屏幕，则应用程序进入了后台。 如果我在这段时间内按下spalsh活动来创建家庭活动，则创建家庭活动的时间为300毫秒，而APP进入了后台。

class Main : AppCompatActivity() {
    private var enabled = true
    var onetime = false
    var response = 0
    private var myshered: SharedPreferences? = null
    private var mDelayHandler: Handler? = null
    private val sPlash: Long = 5000 //6 seconds
    private val mRunnable: Runnable = Runnable {
        if (!isFinishing) {
            test()
        }

    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        window.setFlags(
            WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
            WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
        )
        setContentView(R.layout.splash_screen)
        //Initialize the Handler
        mDelayHandler = Handler()
        //Navigate with delay
        mDelayHandler!!.postDelayed(mRunnable, sPlash)

    }

    public override fun onDestroy() {

        if (mDelayHandler != null) {
            mDelayHandler!!.removeCallbacks(mRunnable)
        }
        super.onDestroy()
    }
