I want my Snackbar to start the animation from the view in red and not at the bottom of the screen as by default, I wanted to give the feeling that the snackbar is appearing behind this view, unfortunately, I don't get good results.
Note: The project I'm working on is not using coordinatorlayout, but I can use.
Activity
class MainActivity : AppCompatActivity() {
private lateinit var snackbar : Snackbar
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
with(binding) {
val view = root
setContentView(view)
snackbar = Snackbar.make(this#MainActivity, view, "Teste", Snackbar.LENGTH_SHORT)
snackbar.anchorView = textText
snackbar.animationMode = BaseTransientBottomBar.ANIMATION_MODE_SLIDE
btnSnackbar.setOnClickListener {
snackbar.show()
}
}
}
}

I tried using elevation to override the snackbar and it doesn't work either.

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"?>

and here is my bottom sheet fragment xml:
<?xml version="1.0" encoding="utf-8"?>
<androidx.appcompat.widget.LinearLayoutCompat

<androidx.recyclerview.widget.RecyclerView
android:id="#+id/tenderList"
android:layout_width="match_parent"

</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
I have an issue with animations. I have defined two simple layouts:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
android:id="#+id/root"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/player1"
android:layout_width="50dp"
android:layout_height="77dp"
android:layout_marginStart="32dp"
android:layout_marginTop="16dp"
android:src="#drawable/two_hearts"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
looking like this:
and
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
android:id="#+id/root"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/player1"
android:layout_width="50dp"
android:layout_height="77dp"
android:layout_marginStart="32dp"
android:layout_marginTop="16dp"
android:src="#drawable/two_hearts"
android:translationY="-60dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
with looks:
The difference between them is android:translationY="-60dp".
I switch between them in the GameFragment.kt:
class GameFragment: Fragment() {
private lateinit var root: ConstraintLayout
private var expanded = false
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View {
root = inflater.inflate(R.layout.fragment_game_hidden, container, false) as ConstraintLayout
root.setOnClickListener {
show()
}
return root
}
private fun show() {
if (expanded) {
updateConstraints(R.layout.fragment_game_hidden)
} else {
updateConstraints(R.layout.fragment_game_shown)
}
expanded = !expanded
}
private fun updateConstraints(#LayoutRes id: Int) {
val newConstraintSet = ConstraintSet()
newConstraintSet.clone(context, id)
val transition = ChangeBounds()
transition.interpolator = AccelerateDecelerateInterpolator()
transition.duration = 1000
newConstraintSet.applyTo(root)
TransitionManager.beginDelayedTransition(root, transition)
}
}
My problem is, the animation is not played at all, the card on the layout just jumps to target location without any transition. Why? I feel like I'm missing something obvious here...
Remove android:translationY="-60dp" in : fragment_game_hidden.xml . Just use margin directly.
Try change to code below:
<androidx.constraintlayout.widget.ConstraintLayout
android:id="#+id/root"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/player1"
android:layout_width="50dp"
android:layout_height="77dp"
android:layout_marginStart="32dp"
android:src="#drawable/two_hearts"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintBottom_toTopOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>
I am having significant difficulty in this and have tried everything imaginable. I am trying to make a card view draggable/swipeable vertically. All I want to accomplish is for the user to be able to swipe/drag the card view up and down. Please see attached photos-this is what I am trying to accomplish.

The RecyclerView shows simple items. Each item has one TextView inside FrameLayout. TextView has no any paddings, but in some cases they appears unexpectedly. The picture below shows that the padding appears immediately after opening the keyboard. The padding appears only if the text contains newline characters. How to fix it ?

class MainActivity : AppCompatActivity() {
lateinit var adapter : MyAdapter
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val recyclerView : RecyclerView = findViewById(R.id.recyclerView)
val button : Button = findViewById(R.id.button)
adapter = MyAdapter();
recyclerView.adapter = adapter;
button.setOnClickListener {
adapter.notifyDataSetChanged()
}
}
}
class MyViewHolder(val view: View) : RecyclerView.ViewHolder(view) {
val textView: TextView;
init {
textView = view.findViewById(R.id.txt)
}
}
class MyAdapter : RecyclerView.Adapter<MyViewHolder>() {
private val data = listOf("Text without \\n ", "multiline\ntext")
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int) =
MyViewHolder(LayoutInflater.from(parent.context)
.inflate(R.layout.list_item, parent, false))
override fun getItemCount() = data.size;
override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
holder.textView.text = data[position]
}
}

The problem is that when the soft keyboard appears, it overlaps the recyclerView. But I want my soft keyboard just push recycler to the top, to be above the keyboard, like with windowSoftInputMode="adjustPan".
But adjustPan is not the option because I need my tool bar.
I have tried adjustResize already, but no luck.
