Перенёс всю основную логику из MainActivity в свой фрагмент, приложение запускается, но при скролле почему то возникает наложение двух Layout'ов, перекопал весь код, с XML вроде всё в порядке. Прилагаю скрины и свой код.
Код Main Activity
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val policy = StrictMode.ThreadPolicy.Builder().permitAll().build()
StrictMode.setThreadPolicy(policy)
setContentView(R.layout.activity_main)
val toolbar = findViewById<androidx.appcompat.widget.Toolbar>(R.id.toolbar)
setSupportActionBar(toolbar)
if (savedInstanceState == null){
supportFragmentManager.beginTransaction()
.add(R.id.fragmentContainerView,
FragmentContact::class.java, null)
.commit()
}
}
override fun onCreateOptionsMenu(menu: Menu?): Boolean {
menuInflater.inflate(R.menu.search_tb_menu, menu)
return true
}
}

Так работает скролл сейчас, идёт наложение
А так должно быть
В чем может быть проблема? В каком направлении копать?
