I realise this question has been asked previously but the answers provided haven't helped me out. I cannot see what is going wrong here.
I have an activity, in which I display a bottom sheet, the bottom sheet has a title and a recyclerview. The recycler view is only displaying one item, regardless of how many are passed to the adapter. It is possible to scroll through the items but only one at any time is visible.
Here is my activity xml:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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"
tools:context=".features.order.automatedcheckout.view.AutomatedCheckoutQRCodeActivity"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/scanBarcodeInstruction"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_marginTop="50dp"
android:text="Scan the barcode to get started"
android:textSize="18sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<androidx.constraintlayout.widget.Guideline
android:id="@+id/loadingGuideline"
android:orientation="horizontal"
app:layout_constraintGuide_percent="0.5"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<ProgressBar
android:id="@+id/progressIndicator"
app:layout_constraintBottom_toTopOf="@+id/loadingGuideline"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="@+id/scanBarcodeInstruction"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<androidx.appcompat.widget.AppCompatImageView
android:id="@+id/qrcodeImageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toBottomOf="@+id/scanBarcodeInstruction"/>
<TextView
android:id="@+id/tenderName"
app:layout_constraintTop_toBottomOf="@+id/qrcodeImageView"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
android:id="@+id/changeTenderButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="10dp"
android:visibility="gone"
android:layout_marginBottom="20dp"
android:layout_marginRight="20dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintRight_toRightOf="parent"
android:text = "Change Tender"/>
</androidx.constraintlayout.widget.ConstraintLayout>
and here is my bottom sheet fragment xml:
<?xml version="1.0" encoding="utf-8"?>
<androidx.appcompat.widget.LinearLayoutCompat
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/bottomSheetLayout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/tenderTitle"
android:layout_marginTop="20dp"
android:layout_marginStart="20dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="SELECT"/>
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/tenderList"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</androidx.appcompat.widget.LinearLayoutCompat>
my bottom sheet fragment:
class TenderBottomSheetFragment : BottomSheetDialogFragment() {
private var _binding: FragmentTenderBottomSheetBinding? = null
private val binding get() = _binding!!
private lateinit var onTenderClicks:(tenderDetails: Pair<Int?, String?>) -> Unit
lateinit var adapter: TenderAdapter
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View {
_binding = FragmentTenderBottomSheetBinding.inflate(inflater, container, false)
adapter = TenderAdapter (
arguments?.parcelableArrayList(ARG_TENDERS)!!,
onTenderClicks
)
return binding.root
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
val layoutManager = LinearLayoutManager(requireContext())
binding.tenderList.layoutManager = layoutManager
binding.tenderList.addItemDecoration(DividerItemDecoration(requireContext(), layoutManager.orientation))
binding.tenderList.adapter = adapter
}
companion object {
fun newInstance(
campusTenders: List<TenderKt>,
onTenderClick: (tenderDetails: Pair<Int?, String?>) -> Unit
): TenderBottomSheetFragment {
val tenderDialogFragment = TenderBottomSheetFragment()
tenderDialogFragment.onTenderClicks = onTenderClick
tenderDialogFragment.apply {
arguments = Bundle().apply {
putParcelableArrayList(ARG_TENDERS, ArrayList(tenders))
}
}
return tenderDialogFragment
}
}
override fun onDestroyView() {
super.onDestroyView()
_binding = null
}
}
I'm sure this is something really simple but unfortunately right now, I'm not seeing it. If anyone could help I would really appreciate it.
UPDATE Here is the recycler item layout:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:tools="http://schemas.android.com/tools"
android:layout_marginStart="10dp"
android:layout_marginEnd="10dp"
xmlns:app="http://schemas.android.com/apk/res-auto">
<TextView
android:id="@+id/campus_tender_name"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
tools:text ="Flex Account"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</androidx.constraintlayout.widget.ConstraintLayout>
I have now updated that to:
<TextView
android:id="@+id/campus_tender_name"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:padding="10dp"
tools:text = "Flex Account"
android:textSize="16sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
and that works fine. So it was the constraint layout in the recycler view item
