Search doesn't work as expected after selecting an item from the BottomSheetDialogFragment and then select the bottomNavigation menu

I have an awkward situation for which I have been trying to find the reason and fix it for two days and I failed.
Let me explain it first.
On launching the app recyclerView in the 'HomeFragment' is filled with data that fetched from Firestore. I have a search bar on the toolbar at the top and when I type in something, it narrows down the list of items in the recyclerView.
I have a FloatingActionButton which will bring up a BottomSheetDialogFragment that contains item categories. When I select a category from it, the recyclerView in the 'HomeFragment' is populated based on the category selected. There is no issues until here.
If I do a search after selecting the category, it narrows down the list of items without any issues. When I select the 'HomeFragment' from the bottomNavigation, after selecting a category from the BottomSheetDialogFragment, the search result is not showing. However, if I select the 'HomeFragment' from the bottomNavigation after selecting any other bottom menu item, but not go to the BottomSheetDialogFragment and select a category, then there is no issue with the search. It happens only when I select the category and then go back to the 'HomeFragment' by hitting the bottom menu. Can somebody help me find and fix the issue?
Following is what I have in the 'HomeFragment' for search.
override fun onCreateOptionsMenu(menu: Menu, inflater: MenuInflater) {
menu.clear() // THIS LINE OF CODE IS ADDED SO THAT WHEN WE SELECT A CATEGORY FROM THE BOTTOMSHEET THE MENU ITEMS WON'T DUPLICATE
inflater.inflate(R.menu.home_menu, menu)
super.onCreateOptionsMenu(menu, inflater)
val item = menu.findItem(R.id.my_search_bar)
val searchView = item?.actionView as SearchView
searchView.setOnQueryTextListener(object : SearchView.OnQueryTextListener {
override fun onQueryTextSubmit(query: String?): Boolean {
srchTempProductsList.clear()
if (query != null) {
if (query.isNotEmpty()) {
srchProductsList.forEach {
if (it.label.toLowerCase(Locale.getDefault()).contains(query)) {
srchTempProductsList.add(it)
}
binding.rvHomeItems.adapter?.notifyDataSetChanged()
}
if (srchTempProductsList.size == 0) {
showCustomAlertDialog()
}
} else {
srchTempProductsList.clear()
srchTempProductsList.addAll(srchProductsList)
binding.rvHomeItems.adapter?.notifyDataSetChanged()
}
}
return false
}
override fun onQueryTextChange(newText: String?): Boolean {
srchTempProductsList.clear()
val searchText = newText!!.toLowerCase(Locale.getDefault())
if (searchText.isNotEmpty()) {
srchProductsList.forEach {
if (it.label.toLowerCase(Locale.getDefault()).contains(searchText)) {
srchTempProductsList.add(it)
}
binding.rvHomeItems.adapter?.notifyDataSetChanged()
}
if (srchTempProductsList.size == 0) {
showCustomAlertDialog()
}
} else {
srchTempProductsList.clear()
srchTempProductsList.addAll(srchProductsList)
binding.rvHomeItems.adapter?.notifyDataSetChanged()
}
return false
}
})
}
I have the following in the 'BottomSheetDialogFragment' to pass the category to the 'HomeFragment'
categoryAdapter.setOnClickListener(object :HomeCategoryListAdapter.OnClickListener{
override fun onClick(position: Int, category: Categories) {
val myFragment = HomeFragment()
val bundle = Bundle()
bundle.putString("category", category.category)
myFragment.arguments = bundle
fragmentManager?.beginTransaction()?.replace(R.id.nav_host_fragment,myFragment)?.commit()
dismiss()
}
})
and the following in the onCreateView of 'HomeFragment'
val bundle = this.arguments
if (bundle!=null) {
if (bundle.getString("category")!="All Products"){
filterCategory = bundle.getString("category")
}else{
filterCategory =null
}
}
and this is how I get the product list in 'HomeFragment'
fun getProductList() {
srchProductsList.clear()
srchTempProductsList.clear()
if (filterCategory!=null){
mFireStore.collection("prods")
.whereEqualTo("category",filterCategory)
.get()
.addOnCompleteListener {
if (it.isSuccessful) {
for (document in it.result) {
val product = document.toObject(Product::class.java)
product.product_id = document.id
srchProductsList.add(product)
}
} else {
}
srchTempProductsList.addAll(srchProductsList)
listProductBasedOnView()
}
.addOnFailureListener {
Log.d("Known Error", "This ....")
}
}else{
mFireStore.collection("prods")
.get()
.addOnCompleteListener {
if (it.isSuccessful) {
for (document in it.result) {
val product = document.toObject(Product::class.java)
product.product_id = document.id
srchProductsList.add(product)
}
} else {
}
srchTempProductsList.addAll(srchProductsList)
listProductBasedOnView()
}
.addOnFailureListener {
Log.d("Known Error", "This ...")
}
}
}

I want to disable other bottoms after I click once

i am working on QuizApp and I get a problem when I choose an answer and click submit it show me the correct and wrong answer and then I should click submit again to go to the next question, i want to disable that , I want when someone click submit he cant change the answer or choose another answer
here is my code
override fun onClick(v: View?) {
when (v?.id) {
R.id.tv_option_one -> {
selectedOptionView(tv_option_one, 1)

if (mSelectedOptionPosition == 0) {
mCurrentPosition++
when {
mCurrentPosition <= mQuestionsList!!.size -> {
setQuestion()
}
else -> {

finish()
// END
}
}
} else {

}
}
}
}
private fun setQuestion() {
val question = mQuestionsList!!.get(mCurrentPosition - 1) // Getting the question from the list with the help of current position.
defaultOptionsView()
if (mCurrentPosition == mQuestionsList!!.size) {
btn_submit.text = "FINISH"
} else {
btn_submit.text = "SUBMIT"
}
progressBar.progress = mCurrentPosition
tv_progress.text = "$mCurrentPosition" + "/" + progressBar.getMax()

in your onclick, change the other views
view.isClickable = false

Android NavigationView prevent selecting item, setCheckedItem not working inside onNavigationItemSelected

This is the code in onNavigationItemSelected
R.id.nav_subscribed -> {
if (prefs.getLong("userid", 0L) == 0L) {
when (currentGal) {
"top" -> {
// navView.setCheckedItem(R.id.nav_top)
// navView.menu.getItem(R.id.nav_top).isChecked = true
}
}
val i = Intent(this, Login::class.java)
this.startActivity(i)
} else {
if(currentGal != "subscriptions"){
getMemes("subscriptions", 0)
}
}
}
I try to prevent nav_subscribed to be checked when the user isn't logged in and check/keep checked nav_top
navView.setCheckedItem(R.id.nav_top)
isn't working and
navView.menu.getItem(R.id.nav_top).isChecked = true
crashed the app. So how to do this? Btw android is awful broken garbage software

navigationView?.setOnNavigationItemSelectedListener {
when (it.itemId) {
R.id.nav_subscribed -> {
// if you don't want an item to be selected return false
return#setOnNavigationItemSelectedListener false
}
R.id.nav_top -> {
}
}
//return true to select the other items
true
}

How can I write a onPrepareOptionsMenu for a PopupMenu with Kotlin in Android Studio?

The function showActionMenu() shows a popup menu, it works well.
I hope to change the title of a menu item when the menu is popup.
I try to add onPrepareOptionsMenu(menu: Menu) in the code, but it doesn't work, how can I fix it?
Code A
private fun showActionMenu() {
val view = mActivity.findViewById<View>(R.id.menuMoreAction) ?: return
PopupMenu(mContext, view).run {
menuInflater.inflate(R.menu.menu_option_action, menu)
/*
onPrepareOptionsMenu(menu: Menu) {
for (item in menu){
if (item.itemId == R.id.menuMoreActionSelectAll){
item.title = "My new title"
}
}
}
*/
setOnMenuItemClickListener {
when (it.itemId) {
R.id.menuMoreActionSelectAll -> {
mHomeViewModel.setSelectStatus(ESelect.SelectAll)
}
...
}
true
}
show()
}
}

You call show() immediately, so the menu is being shown immediately. Therefore you don't need any onPrepareOptionsMenu() call - just run that code immediately after your call to inflate():
PopupMenu(mContext, view).run {
menuInflater.inflate(R.menu.menu_option_action, menu)
for (item in menu){
if (item.itemId == R.id.menuMoreActionSelectAll){
item.title = "My new title"
}
}
setOnMenuItemClickListener {
when (it.itemId) {
R.id.menuMoreActionSelectAll -> {
mHomeViewModel.setSelectStatus(ESelect.SelectAll)
}
...
}
true
}
show()
}
Of course, if you're always setting the title of R.id.menuMoreActionSelectAll, you should just set that title in your R.menu.menu_option_action and skip your 'prepare' work entirely.

Double clicking on BottomSheetDialog quickly gives two dialog

I have a bottom sheet dialog fragment that i use as a menu for my bottom app bar.
If i click on the menu icon really quick two times, the dialog shows up two times and i have to close it two times which is annoying.
My code is as follows:
ActivityHome.kt
override fun onOptionsItemSelected(item: MenuItem): Boolean {
return when (item.itemId) {
android.R.id.home -> {
if(mBottomNavDrawerFragment != null && mBottomNavDrawerFragment!!.dialog!!.isShowing){
mBottomNavDrawerFragment?.dismiss()
return false
}
mBottomNavDrawerFragment = RoundedBottomSheetDialogFragment()
mBottomNavDrawerFragment?.show(supportFragmentManager, mBottomNavDrawerFragment?.tag)
true
}
R.id.BottomAppBar_fromHomeActivity_MenuMain_Search -> {
Toast.makeText(this, "Not Implemented yet!", Toast.LENGTH_SHORT).show()
false
}
else -> true
}
}
Can anyone help? Thanks

Show the dialogFragment using a tag. Check if the tag exists in the stack before showing it again
if(getChildFragmentManager().findFragmentByTag(FragmentDialog.TAG) == null) {
fragmentDialog.show(getChildFragmentManager(), FragmentDialog.TAG);
}

You can do a little bit hack here. Here is the code.
private var saveClickCounter = 0
override fun onOptionsItemSelected(item: MenuItem?): Boolean {
return when (item?.itemId) {
R.id.home -> {
if (saveClickCounter++ == 0) {
//Your Dialog Showing Code
Handler().postDelayed({
saveClickCounter=0
},1000)
}
true
}
R.id.BottomAppBar_fromHomeActivity_MenuMain_Search -> {
Toast.makeText(this, "Not Implemented yet!", Toast.LENGTH_SHORT).show()
false
}
else -> true
}
}
Make a variable saveClickCounter to store your counts.
On clicks increase the value of saveClickCounter and change it to zero after N seconds of delayed. I used 1 second in below code.
