我正在尝试在ViewPager上实现TableLayout,但是我不能使用setup.ViewViewr方法,因为android studio表示它是未解决的引用。
此TableLayout和ViewPager应该在片段(AboutFragment.kt)中实现
如果没有TabLayout,我的ViewPager可以很好地工作,我的意思是我可以在片段之间滑动。
有人可以解决吗?
这是我的AboutFragment:
package hr.ferit.brunozoric.taskie.ui.fragments
import android.os.Bundle
import android.view.View
import androidx.fragment.app.Fragment
import hr.ferit.brunozoric.taskie.R
import hr.ferit.brunozoric.taskie.ui.adapters.ViewPagerAdapter
import hr.ferit.brunozoric.taskie.ui.fragments.base.BaseFragment
import kotlinx.android.synthetic.main.fragment_about.*
class AboutFragment: BaseFragment() {
override fun getLayoutResourceId(): Int {
return R.layout.fragment_about
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
setupPager()
}
private fun setupPager() {
viewPager.adapter = ViewPagerAdapter(fragmentManager!!)
tabLayout.setupWithViewPager(viewPager) // I have error in this line :(
}
companion object{
fun newIstance(): Fragment {
return AboutFragment()
}
}
}
这是我的ViewPagerAdapter:
package hr.ferit.brunozoric.taskie.ui.adapters
import androidx.fragment.app.Fragment
import androidx.fragment.app.FragmentManager
import androidx.fragment.app.FragmentStatePagerAdapter
import hr.ferit.brunozoric.taskie.ui.fragments.AboutAplicationFragment
class ViewPagerAdapter(manager :FragmentManager) : FragmentStatePagerAdapter(manager) {
companion object{
const val NUM_OF_PAGES =2
const val PAGE_ONE_TITLE = "About Application"
const val PAGE_TWO_TITLE = "About Author"
}
private val frags = mutableListOf<Fragment>(AboutAplicationFragment(),AboutAplicationFragment())
private val titles = mutableListOf(PAGE_ONE_TITLE, PAGE_TWO_TITLE)
override fun getItem(position: Int): Fragment {
return frags[position]
}
override fun getPageTitle(position :Int) : String{
return titles[position]
}
override fun getCount(): Int {
return NUM_OF_PAGES
}
}
这是带有ViewPager和TabLayout的XML文件:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<androidx.viewpager.widget.ViewPager
android:id="@+id/viewPager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/tabLayout"
/>
<TableLayout
android:id="@+id/tabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
/>
</RelativeLayout>
答案 0 :(得分:0)
您使用的是<TableLayout>
而不是<TabLayout>
。
