В следующем коде я получаю следующие ошибки:
tablayout : Никакого говорится о том, что
не смог создать одно или несколько классов < /p>
Я искал онлайн, и все подобные проблемы с Edittex Код. < /p>
< /code>
Вот мой основной файл активности < /p>
То, что я попробовал, указано выше < /p>
package com.example.sahir_sood_myruns1
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import androidx.viewpager2.widget.ViewPager2
import com.google.android.material.tabs.TabLayout
class MainActivity : AppCompatActivity() {
// Declare variables for TabLayout, ViewPager2, and the adapter
private lateinit var tabLayout: TabLayout
private lateinit var viewPager2: ViewPager2
private lateinit var adapter: FragmentPageAdapter
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main) // Set the content view to your XML layout
// Find the TabLayout and ViewPager2 in the layout by their respective IDs
tabLayout = findViewById(R.id.tabLayout)
viewPager2 = findViewById(R.id.viewPager2)
// Initialize the adapter with the FragmentManager and the lifecycle
adapter = FragmentPageAdapter(supportFragmentManager, lifecycle)
// Add tabs to the TabLayout, each with a title (Start, History, Settings)
tabLayout.addTab(tabLayout.newTab().setText("Start").setContentDescription("Start Tab"))
tabLayout.addTab(tabLayout.newTab().setText("History").setContentDescription("History Tab"))
tabLayout.addTab(tabLayout.newTab().setText("Settings").setContentDescription("Settings Tab"))
// Set the adapter for the ViewPager2 so it knows which fragments to display
viewPager2.adapter = adapter
// Add a listener to handle user interaction with the TabLayout (i.e., when the user clicks on a tab)
tabLayout.addOnTabSelectedListener(object: TabLayout.OnTabSelectedListener {
// This method is called when a tab is selected

viewPager2.currentItem = tab.position
}
}

}
override fun onTabReselected(tab: TabLayout.Tab?) {
