Android material TextInputLayout doesn't reconnect outline after setHintEnabled(false)

Using com.google.android.material:material:1.6.1, when setting hint enabled to true and then to false, the outline gets broken. Here is the example code.
MainActivity.kt
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val someHintButton = findViewById<MaterialButton>(R.id.someHintButton)
val noHintButton = findViewById<MaterialButton>(R.id.noHintButton)
val textInput = findViewById<TextInputEditText>(R.id.textInput)
val textLayout = findViewById<TextInputLayout>(R.id.textLayout)
someHintButton.setOnClickListener {
textInput.setText("Some text")
textLayout.setHintEnabled(true)
textLayout.setHint("Entered text:")
}
noHintButton.setOnClickListener {
textLayout.setHint(null)
textLayout.setHintEnabled(false)
textInput.setText("Some text will be entered here")
}
}
}

Screen after launch:
Screen after 'Some hint' pressed:
Screen after 'No hint' pressed:
setHint(null) or setHint("") don't do any difference. Why doesn't outline get reconnected? Please advise.

Scroll to top of RecyclerView using setOnClickListener

I have this home button in top bar:
val activity: ImageButton =findViewById(R.id.activity)
activity.setOnClickListener{
startActivity(Intent(this, ActivitySearch::class.java))
}
Instead of going to a new page, I want to be able to just put a "to top" intent, I have tried to replace:
startActivity(Intent(this, ActivitySearch::class.java))
with
mRecyclerView.smoothScrollToPosition(0);
But this does not work, any ideas? I do have a RecyclerView in use so half way down, I want to be able to click the above button and it goes straight to the top.
Total code:
private val apiService by lazy {
ApiClient.create()
}
private var taskData : ArrayList<TaskResponse> = arrayListOf();
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val activity: ImageButton =findViewById(R.id.activity)
activity.setOnClickListener{
startActivity(Intent(this, ActivitySearch::class.java))
}
val searchbutton:ImageButton=findViewById(R.id.searchbutton)
searchbutton.setOnClickListener{
startActivity(Intent(this, ActivitySearch::class.java))
}
val saves:ImageButton=findViewById(R.id.saves)
saves.setOnClickListener{
startActivity(Intent(this, ActivitySaves::class.java))
}
val settings:ImageButton=findViewById(R.id.settings)
settings.setOnClickListener{
startActivity(Intent(this, ActivitySettings::class.java))
}
loadData();
}
private fun loadData(){
var data = apiService.getMainData();
data.enqueue(object : Callback<ArrayList<TaskResponse>> {
override fun onResponse(
call: Call<ArrayList<TaskResponse>>,
response: Response<ArrayList<TaskResponse>>
) {
if (response.code() == 200) {
taskData = response.body()!!;
displaydata();
}
}
override fun onFailure(call: Call<ArrayList<TaskResponse>>, t: Throwable) {
Log.d("-----------------", t.toString())
}
})
}
private fun displaydata(){
var recyclerView = findViewById<RecyclerView>(R.id.mainList);
var adapter = TaskAdapter(this, taskData);
recyclerView.layoutManager = LinearLayoutManager(this)
recyclerView.adapter = adapter
val swipeRefreshLayout: SwipeRefreshLayout = findViewById(R.id.swipeRefreshLayout)
// load data on swipe refresh.
swipeRefreshLayout.setOnRefreshListener { loadData() }
// Disable the refreshing after data load
swipeRefreshLayout.isRefreshing = false
}

This should work for going to the top of the recyclerView.
mRecyclerView.smoothScrollToPosition(0);
or
mRecyclerView.scrollToPosition(0);
When your list changes in recyclerView adapter, you should use that code. Make sure other parts of the code. This should work.

Using a comments answer from #cactustictacs, I edited my code to this and it worked:
val activity: ImageButton =findViewById(R.id.activity)
val mRecyclerView = findViewById<RecyclerView>(R.id.mainList)
activity.setOnClickListener{
mRecyclerView.smoothScrollToPosition(0)
}

Android drawer layout header - cannot access it

In my past project from the beggining of the year I have set the content of my drawerHeader in the mainActivity code. I am rewriting it and now it seems impossible to access the header through binding in MainActivity.
I have a usual drawer layout in the activity -> navigation view -> drawer header.
I used to access it through simple binding.layoutDrawer.userDataHeader but it doesn't find userDataHeader no matter what I do. What am I doing wrong?

Invisible Layout not visible when make it visible in Android

I am trying to implement something like viewing a list of items in RecyclerView (id=schedule_recycler_view) which parent layout is a CardView (id = info_card_view). The Item is fetched by API call. If no item found, or connectivity issue, I want to view another layout (id = no_list_layout) which is Visibility-Gone at the first time.
But The problem I face, although I make the visibility of that layout (id = no_list_layout) visible programmatically, it did not visible.
Can anyone help?

tuitionScheduleAdapter.notifyChanged(scheduleData.schedules)
}
}

} else {

}
}

You should use no_list_layout.visibility = View.VISIBLE

Change your view visibility code
try this :
Kotlin:
if (list.size == 0) {
no_list_layout.visibility= View.VISIBLE
} else {
adapter.notifyChanged(list)
}
In Java
if (list.size == 0) {
no_list_layout.setVisibility(View.VISIBLE)
} else {
adapter.notifyChanged(list)
}

You can try with runOnUiThread.
runOnUiThread runs the specified action on the UI thread. If the
current thread is the UI thread, then the action is executed
immediately. If the current thread is not the UI thread, the action is
posted to the event queue of the UI thread.
context?.runOnUiThread(Runnable {
// Your Logic
if (list.size==0) {
no_list_layout.visibility= View.VISIBLE
} else {
// Your work
}
})

You have to hide your recyclerview also and make it visible in the other case like this:
if (scheduleData.schedules.size == 0) {
schedule_recycler_view.visibility = View.GONE
no_list_layout.visibility = View.VISIBLE
} else {
schedule_recycler_view.visibility = View.VISIBLE
no_list_layout.visibility = View.GONE
tuitionScheduleAdapter.notifyChanged(scheduleData.schedules)
}

At last, I found the actual culprit. It was in the layout file. I recreate the layout

Android gridview in fragment can't scrolling

I have one page called products. When page is loaded it shows productsfragment. This fragment has one RecyclerView which doesn't have any problem. On selecting a product a new fragment opens up and shows the list of product prices fragment. This fragment has one RecyclerView and the scrolling here doesn't works.
I tried gridview and cardview but they too are not scrolling. I tried gridview in scroll view or nested scroll view, they are also not scrolling.
here is my fragment with RecyclerView which is not scrolling
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<android.support.v7.widget.RecyclerView

and its my RecyclerView item view

and my adapter
class PriceAdapter(val priceList : List<ProductPrice>,

override fun onCreateViewHolder(p0: ViewGroup, p1: Int): ViewHolder {
return ViewHolder(LayoutInflater.from(context).inflate(R.layout.gv_product_prices, p0, false))

}
}
class ViewHolder (view: View) : RecyclerView.ViewHolder(view) {
val txtPriceName = view.txtPriceName!!
val txtPrice = view.txtPrice!!
}
and my fragment code
class SOrderFragment_Step1 : Fragment() {
private var _priceRepository = ProductPriceRepository(OrderRepository.orderSelect!!)
private var priceAdapter: PriceAdapter? = null
private var prices: List<ProductPrice>? = null
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,

super.onViewCreated(view, savedInstanceState)
configurePrices()
}

prices = _priceRepository.getPriceByProductId(OrderRepository.currentProduct!!.getId())
gvProductPrices.layoutManager = GridLayoutManager(OrderRepository.orderSelect!!, 2)
gvProductPrices.adapter = PriceAdapter(prices!!, this, OrderRepository.orderSelect!!)
}
fun priceSelect(price: ProductPrice) {
Toast.makeText(OrderRepository.orderSelect!!, price.getDescription(), Toast.LENGTH_LONG).show()
}
}
and also fragment change like this
val manager = this.fragmentManager!!.beginTransaction()
manager.setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out)
manager.replace(R.id.fragmentProductSteps, SOrderFragment_Step1(), "detailFragment").commit()

How can i fix this issue ?

Sugession: Why are you using grid view and setting adapter to it where you have another approach and commonly used approach.
Which is to use recycler view and set its layout manager as GridLayout manager
Below single line will make your job done
recyclerView.setLayoutManager(new GridLayoutManager(this, numberOfColumns));
