how to set viewpager with tabLaout in fragment MVVM and DataBinding?

Question

I want to setup my viewpager with tablelayout in fragment

fragment:

class HomeFragment : Fragment() {

lateinit var bindingFragment: FragmentHomeBinding

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View {
    // Inflate the layout for this fragment
    bindingFragment =
        DataBindingUtil.inflate(inflater, R.layout.fragment_home, container, false)
    return bindingFragment.root
}

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)

    bindingFragment.viewPagerActivity = this
}

companion object {

    @JvmStatic
    @BindingAdapter("set_view_pager")
    fun setViewPager(viewPager: ViewPager, context: ActivityMainBinding) {

        val ls2 = arrayListOf<ModelAdapterVpCafeList2>()

        ls2.add(
            ModelAdapterVpCafeList2(
                1,
                "cafename",
                "ali",
                4.2f,
                "adress khione",
                "2",

        val ls: List<ModelAdapterVpCafeList> = arrayListOf(

            ModelAdapterVpCafeList("همه", ls2),

        val vpAdapter = AdapterVpCafeList(ls)

        viewPager.adapter = vpAdapter

    }

    @JvmStatic
    @BindingAdapter("set_tab_layout")
    fun setTabLayout(tabLayout: TabLayout, viewPager: ViewPager) {
        tabLayout.setupWithViewPager(viewPager, true)
    }

}

}

adapter:

class AdapterVpCafeList(private val ls: List<ModelAdapterVpCafeList>):  PagerAdapter(){

override fun instantiateItem(container: ViewGroup, position: Int): Any {

    val inflater = LayoutInflater.from(container.context)
    val binding: LayooutRecyclerviewHomeSearchBinding =  DataBindingUtil.inflate(inflater, R.layout.layoout_recyclerview_home_search, container, false)

    binding.cafeList = ls[position]
    container.addView(binding.root)

    return binding.root
}

override fun getPageTitle(position: Int): CharSequence = ls[position].name

override fun destroyItem(container: ViewGroup, position: Int, `object`: Any) = container.removeView(`object` as View)

override fun getCount(): Int = ls.size

override fun isViewFromObject(view: View, `object`: Any): Boolean = view == `object`

}

my layout:

<data>

    <variable
        name="viewPagerActivity"
        type="ir.arinateam.cafechejori.view.fragments.HomeFragment" />

    <import type="android.view.View"/>
</data>
<com.google.android.material.tabs.TabLayout
            android:id="@+id/tabLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginStart="20dp"
            android:layout_marginTop="10dp"
            android:layout_marginEnd="20dp"
            app:set_tab_layout="@{vp}">

        </com.google.android.material.tabs.TabLayout>

        <androidx.viewpager.widget.ViewPager
            android:id="@+id/vp"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginStart="20dp"
            android:layout_marginEnd="20dp"
            app:set_view_pager="@{viewPagerActivity}"/>

but in layout, app:set_view_pager=@{viewPagerActivity} I have this error

Cannot find a setter for that accepts parameter type 'ir.arinateam.cafechejori.view.fragments.HomeFragment'

how can I solve this problem?

Answer 1

I solved it by clean project and rebuild project multiple times.
