另一方面，您可以通过以下代码使用 viewpager2:

In other hand you can use viewpager2 with this code:

myPagerAdapter.kt

import androidx.fragment.app.Fragment
import androidx.fragment.app.FragmentActivity
import androidx.viewpager2.adapter.FragmentStateAdapter


class PagerAdapterAccounting internal constructor(fm: FragmentActivity) : FragmentStateAdapter(fm) {

    override fun getItemCount(): Int {
        return mFragmentList.size
    }

    override fun createFragment(position: Int): Fragment {
        return mFragmentList[position]
    }

    private val mFragmentList = ArrayList<Fragment>()
    private val mFragmentTitleList = ArrayList<String>()


    fun addFragment(fragment: Fragment, title: String) {
        mFragmentList.add(fragment)
        mFragmentTitleList.add(title)
    }

    fun getTabTitle(position: Int): String {
        return mFragmentTitleList[position]
    }
}

用户界面:

 <com.google.android.material.tabs.TabLayout
        android:id="@+id/tabLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabGravity="fill"
        app:tabIndicatorColor="@color/colorPrimaryDark"
        app:tabIndicatorHeight="2dp"
        app:tabMode="fixed"
        app:tabSelectedTextColor="@color/colorPrimary" />

    <androidx.viewpager2.widget.ViewPager2
        android:id="@+id/viewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

及用法:

val fragmentAdapter = PagerAdapterAccounting(this) //must be a fragmentActivity

fragmentAdapter.addFragment(SampleFragment.newInstance(), "theSampleTitle1")
fragmentAdapter.addFragment(SampleFragment2.newInstance(), "theSampleTitle2")

viewPager.adapter = fragmentAdapter

TabLayoutMediator(tabLayout, viewPager,
                TabLayoutMediator.TabConfigurationStrategy { tab, position -> tab.text =  fragmentAdapter.getTabTitle(position) }).attach()

别忘了添加 appcompatX &材料库:

dont forget to add appcompatX & material lib:

implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'com.google.android.material:material:1.2.0-alpha02'

希望能解决您的问题.
