Kotlin-加载片段时未显示Viewpager

最近遇到了一个我要解决的问题,但是我找不到解决方案。 在我的项目中,我得到了一个片段,该片段使布局夸大,其中包含一个viewPager。到这里为止一切正常,但是当我运行该项目以在智能手机上查看该项目时,除了viewpager以外,所有内容都会显示出来。我是否有需要重新考虑的地方?这是我在viewpager方法的各个片段上得到的onCreateView的结果:

    viewPager = conteudo_feridas.findViewById<View>(R.id.viewPagerGaleria) as ViewPager
    val adapter = ViewPageAdapter(activity!!.application)
    viewPager.adapter = adapter
    viewPager.currentItem = images.size

在我的viewpager中,我得到了以下代码:

class ViewPageAdapter(private val context: Context) : PagerAdapter(){
    private var layoutInflater:LayoutInflater?= null

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

    override fun getCount(): Int {
        return numeroFotos.size
        return dias.size
        return images.size
    }

    override fun instantiateItem(container: ViewGroup, position: Int): Any {
        /**Set our vals to "inflate"**/
        layoutInflater = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
        val v = layoutInflater!!.inflate(R.layout.custom_layout, null)
        val nrFotos = v.findViewById<View>(R.id.dados_galeria_nr_fotos) as TextView
        val dados = v.findViewById<View>(R.id.dados_galeria_data) as TextView
        val image = v.findViewById<View>(R.id.image_view) as ImageView

   vp.addView(v, 0)

   return v

Viewpager的布局也是如此:

<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.v4.view.ViewPager
    android:id="@+id/viewPagerGaleria"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="8dp"
    app:layout_constraintTop_toBottomOf="@id/pageIndicatorView">
</android.support.v4.view.ViewPager>

<com.rd.PageIndicatorView
    android:id="@+id/pageIndicatorView"
    android:layout_width="wrap_content"
    app:layout_constraintBottom_toTopOf="@id/viewPagerGaleria"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintLeft_toLeftOf="parent"
    app:piv_padding="50dp"
    app:piv_animationType="scale"
    app:piv_viewPager="@id/viewPagerGaleria"
    android:layout_height="wrap_content"
    />
