Android 意图,相同 activity 正在重复

Android intent, Same activity is repeating

嗨,我第一次在 Kotlin 中编写 android 代码,当我尝试使用 Intent 而不是转到下一页时,相同的 activity 正在重复。我在这里给出我的activity代码

class MainActivity : Activity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        // get reference to button
        val btnStart = findViewById<Button>(R.id.start_button)
        // set on-click listener
        btnStart.setOnClickListener {
            Toast.makeText(this@MainActivity, "You clicked me.", Toast.LENGTH_SHORT).show()
            val intent = Intent(this, QuestionActivity::class.java).apply {
            }
            startActivity(intent)
        }
    }
}
val intent = Intent(this, QuestionActivity::class.java).apply {
            }
            startActivity(intent)

val intent = Intent(this, QuestionActivity::class.java)
startActivity(intent)

startActivity(Intent(这, QuestionActivity::class.java))
