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 ...")
}
}
}
