ViewPager2片段内容在关注EditText时消失

Question

当我点击EditText时，viewpager2的内容会消失，当我开始键入内容时，内容会重新出现，当我旋转手机时，内容也会重新出现你可以在这里的视频中看到问题

这是我创建tablayout和viewpager2的类

class ATab (activity: AppCompatActivity,viewPagerId: Int,tabLayoutId: Int) {
val items = arrayListOf<ItemModel>()
val adapter = Adapter(items , activity)
val viewpager = activity.findViewById<ViewPager2>(viewPagerId)
val tabLayout = activity.findViewById<TabLayout>(tabLayoutId)
fun add(fragment : Fragment ,title : String ="" ,icon : String = ""){
items.add(ItemModel(fragment,title,icon))
adapter.notifyDataSetChanged()
}
init {
viewpager.adapter = adapter
TabLayoutMediator(tabLayout,viewpager){tab, position ->
if (!items[position].title.equals("")){
tab.text = items[position].title
}
if (!items[position].icon.equals("")){
val res_id = activity.resources.getIdentifier(items[position].icon,"drawable",activity.packageName)
tab.icon = activity.getDrawable(res_id)
}
}.attach()
}
inner class Adapter(val model : List<ItemModel>, context: AppCompatActivity) : FragmentStateAdapter(context){
override fun getItemCount(): Int {
return  model.count()
}
override fun createFragment(position: Int): Fragment = model[position].fragment
}
inner class ItemModel(var fragment : Fragment ,var title : String ,var icon : String)}

这是我的活动

class LoginActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
setTheme(R.style.AppTheme2)
super.onCreate(savedInstanceState)
overridePendingTransition(
R.anim.fade_in,
R.anim.fade_out
)
requestWindowFeature(Window.FEATURE_NO_TITLE)
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN)
setContentView(R.layout.activity_login)
val atab = ATab(this,R.id.View_splash,R.id.Tab_splash)
atab.add(SignInFragment(),"ورود")
atab.add(SignUpFragment(),"ثبت نام")
}
override fun onResume() {
super.onResume()
overridePendingTransition(
R.anim.fade_in,
R.anim.fade_out
)
}}

这是我的布局

Answer 1

我发现了错误在我的片段布局中，我在没有任何理由的情况下使用了一个ConstraintLayout到另一个所以在删除后，bug修复了。
