I am implementing a recycler view with diff util, but the first time I send the list to the adapter, the recycler view is not notified about the new list. Only the second time I update the list does the recycler receive the notification. I tried several solutions I found in similar questions but none worked. If anyone can help, thanks in advance.
Here is my code:
Adapter:
class UserListAdapter : Adapter<UserListItemViewHolder>() {
private var mUsers = mutableListOf<User>()
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): UserListItemViewHolder =
UserListItemViewHolder.create(parent)
override fun onBindViewHolder(holder: UserListItemViewHolder, position: Int) {
holder.bind(mUsers[position])
}
override fun getItemCount(): Int = mUsers.size
fun updateUsersList(users: List<User>) {
val diffCallback = UserListDiffCallback(this.mUsers, users)
val diffResult = DiffUtil.calculateDiff(diffCallback)
this.mUsers.clear()
this.mUsers.addAll(users)
diffResult.dispatchUpdatesTo(this)
}
}
UsersListDiffCallback:
class UserListDiffCallback(
private val oldList: List<User>,
private val newList: List<User>
) : DiffUtil.Callback() {
override fun areItemsTheSame(oldItemPosition: Int, newItemPosition: Int): Boolean {
return oldList[oldItemPosition].username == newList[newItemPosition].username
}
override fun getOldListSize(): Int {
return oldList.size
}
override fun getNewListSize(): Int {
return newList.size
}
override fun areContentsTheSame(oldItemPosition: Int, newItemPosition: Int): Boolean {
return true
}
}
ViewModel:
#HiltViewModel
class MainViewModel #Inject constructor(
private val getUsersUseCase: GetUsersUseCase
) : ViewModel() {
private val _usersResultStatus = MutableLiveData<ResultStatus>(NotLoading)
val usersResultStatus: LiveData<ResultStatus>
get() = _usersResultStatus
private val _users = MutableLiveData<MutableList<User>?>()
val users: LiveData<MutableList<User>?>
get() = _users
fun getUsers() {
viewModelScope.launch {
try {
_usersResultStatus.value = Loading
_users.value = getUsersUseCase()
} catch (error: Throwable) {
_usersResultStatus.value = Error(error)
} finally {
_usersResultStatus.value = NotLoading
}
}
}
}
And where I update the list in the activity:
#AndroidEntryPoint
class MainActivity : AppCompatActivity() {
private var _binding: ActivityMainBinding? = null
private val binding: ActivityMainBinding get() = _binding!!
private val viewModel: MainViewModel by viewModels()
private val usersAdapter = UserListAdapter()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
_binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
initUsersAdapter()
observeStates()
viewModel.getUsers()
}
private fun initUsersAdapter() {
with(binding.recyclerView) {
setHasFixedSize(true)
adapter = usersAdapter
}
}
private fun observeStates() {
viewModel.usersResultStatus.observe(this) { resultStatus ->
setProgressbarVisibility(resultStatus is Loading)
if (resultStatus is Error) {
Toast.makeText(
this#MainActivity,
getString(R.string.error),
Toast.LENGTH_SHORT
).show()
}
}
viewModel.users.observe(this) { users ->
users?.let {
usersAdapter.updateUsersList(users.toMutableList())
}
}
}
private fun setProgressbarVisibility(show: Boolean) {
binding.progressBar.visibility = if (show) View.VISIBLE else View.GONE
}
}
Trying to add item range changed to your code works like this for me
fun updateUsersList(users: List<User>) {
val diffCallback = UserListDiffCallback(this.mUsers, users)
val diffResult = DiffUtil.calculateDiff(diffCallback)
this.mUsers.clear()
this.mUsers.addAll(users)
diffResult.dispatchUpdatesTo(this)
notifyItemRangeChanged(0, users.size)
}
DiffUtil do not update items recyclerview with the same id and not same the content,
The model has [id : Int and title : String]. I want to the diffUtilCallBack check items with the same id and not same title and update to recyclerview
Please help me fix it
my DiffUtil CallBAck
class DiffCB(
val oldl : ArrayList<Test>,
val newl : ArrayList<Test>
) : DiffUtil.Callback() {
override fun getOldListSize(): Int {
return oldl.size
}
override fun getNewListSize(): Int {
return newl.size
}
override fun areItemsTheSame(oldItemPos: Int, newItemPos: Int): Boolean {
return oldl[oldItemPos].id == newl[newItemPos].id
}
override fun areContentsTheSame(oldItemPos: Int, newItemPos: Int): Boolean {
return oldl[oldItemPos].title.equals(newl[newItemPos].title)
}
}
my Adapter.kt
class TestAdapter(val click: TestClick) :
RecyclerView.Adapter<TestAdapter.TestVH>() {
var list: ArrayList<Test> = ArrayList()
inner class TestVH(val bin: ItemTestBinding) : RecyclerView.ViewHolder(bin.root) {
fun bind(test: Test) {
bin.tvTestId.text = "[id: ${test.id}]"
bin.tvTestTitle.text = test.title
bin.cbTest.isChecked = test.select
bin.cbTest.setOnClickListener {
click.click(test)
}
}
}
fun sumbitData(newl: ArrayList<Test>) {
val diff = DiffCB(this.list, newl)
val diffResult = DiffUtil.calculateDiff(diff)
list.clear()
this.list.addAll(newl)
diffResult.dispatchUpdatesTo(this)
}
override fun getItemCount(): Int {
return list.size
}
override fun onBindViewHolder(holder: TestVH, position: Int) {
holder.bind(list[position])
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): TestVH {
return TestVH(ItemTestBinding.inflate(LayoutInflater.from(parent.context),
parent, false))
}
}
my Activity.kt
class TestActivity : AppCompatActivity(), TestClick {
private var list : ArrayList<Test> = ArrayList()
private lateinit var bin : ActivityTestBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
bin = ActivityTestBinding.inflate(layoutInflater)
setContentView(bin.root)
val viewModel = ViewModelProviders.of(this).get(TestViewModel::class.java)
val manager = LinearLayoutManager(this)
bin.rvTest.layoutManager = manager
val adapter = TestAdapter(this)
bin.rvTest.adapter = adapter
//init first data
viewModel.setTests(initData())
viewModel.getTests().observe(this, Observer {
adapter.sumbitData(it as ArrayList<Test>)
})
bin.btnTest.setOnClickListener{
viewModel.setTests(updateData())
}
}
fun updateData() : ArrayList<Test> {
for (i in 2..6) {
var test = Test()
test.id = i
test.title = "title test $i update"
list.add(test)
}
return list
}
fun initData() : ArrayList<Test> {
for (i in 1..3) {
var test = Test()
test.id = i
test.title = "title test $i"
list.add(test)
}
return list
}
override fun click(test: Test) {
Toast.makeText(this, "${test.id} ${test.title}", Toast.LENGTH_SHORT).show()
}
}
it is first data
after update data, items with the same id have not been updated (id 2, 3)
I am using kotlin language with android studio. I want to get the properties of the element I clicked in the RecyclerView.
Ben bu kod ile saderc id alabiliyorum
Ex: date
ListAdapter.kt
class ListAdapter(
private val context: Context
) : RecyclerView.Adapter<ListAdapter.ListViewHolder>() {
private var dataList = mutableListOf<Any>()
private lateinit var mListener: onItemClickListener
interface onItemClickListener {
fun onItemClick(position: Int)
}
fun setOnItemClickListener(listener: onItemClickListener) {
mListener = listener
}
fun setListData(data: MutableList<Any>) {
dataList = data
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ListViewHolder {
val view = LayoutInflater.from(context).inflate(R.layout.item_row, parent, false)
return ListViewHolder(view)
}
override fun onBindViewHolder(holder: ListViewHolder, position: Int) {
val question: Questionio = dataList[position] as Questionio
holder.bindView(question)
}
override fun getItemCount(): Int {
return if (dataList.size > 0) {
dataList.size
} else {
return 0
}
}
inner class ListViewHolder(itemView: View, listener: onItemClickListener) :
RecyclerView.ViewHolder(itemView) {
fun bindView(questionio: Questionio) {
itemView.findViewById<TextView>(R.id.txt_policlinic).text = questionio.policlinic
itemView.findViewById<TextView>(R.id.txt_title).text = questionio.title
itemView.findViewById<TextView>(R.id.txt_description).text = questionio.description
itemView.findViewById<TextView>(R.id.txt_date).text = questionio.date
itemView.findViewById<TextView>(R.id.txt_time).text = questionio.time
}
init {
itemView.setOnClickListener {
listener.onItemClick(adapterPosition)
}
}
}
}
My code in onCreateView inside list fragment.Edit
ListFragment
recyclerView.layoutManager = LinearLayoutManager(requireContext())
recyclerView.adapter = adapter
observeData()
adapter.setOnItemClickListener(object : ListAdapter.onItemClickListener {
override fun onItemClick(position: Int) {
showShortToast(position.toString())
}
})
this function is also my observationData(),
I made new edits
private fun observeData() {
binding.shimmerViewContainer.startShimmer()
listViewModel.fetchQuestinData("questions",
requireContext())
.observe(viewLifecycleOwner, {
binding.shimmerViewContainer.startShimmer()
binding.shimmerViewContainer.hideShimmer()
binding.shimmerViewContainer.hide()
adapter.setListData(it)
adapter.notifyDataSetChanged()
})
}
You can pass highOrderFuction into the adapter then setonclickListener for any view you want. Like this:
class ListAdapter(
private val context: Context,
private val onItemClick:(questionio: Questionio)->Unit
) : RecyclerView.Adapter<ListAdapter.ListViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ListViewHolder {
val view = LayoutInflater.from(context).inflate(R.layout.item_row, parent, false)
return ListViewHolder(view,onItemClick)
}
...
inner class ListViewHolder(itemView: View,private val onItemClick:(questionio: Questionio)->Unit) : RecyclerView.ViewHolder(itemView) {
fun bindView(questionio: Questionio) {
//set on any view you want
itemView.findViewById<TextView>(R.id.root_view_id).
setOnClickListener{onItemClick(questionio)}
itemView.findViewById<TextView>(R.id.txt_policlinic).text =
questionio.policlinic
itemView.findViewById<TextView>(R.id.txt_title).text = questionio.title
itemView.findViewById<TextView>(R.id.txt_description).text =
questionio.description
itemView.findViewById<TextView>(R.id.txt_date).text = questionio.date
itemView.findViewById<TextView>(R.id.txt_time).text = questionio.time
}
}
}
Like title I can't get correct item data, now imagine I have 2 recycler view list on my main fragment, one recycler view is vertical, other horizontal. If I use only one recycler everything is working fine. But when I add other one it's opening items randomly, but that random data openings only random both recyclers positions. Like my first recycler have [a,b,c,d] , other recycler have [e,f,g,h]. When I click first item of first recycler its go to other fragment which shows detail, its opening e instead of a, if I go back and retry it, its opening e again, retry and its a !! so its opening randomly, why this is happening why can't I open correct data? I put Log.d on my adapters and when I click recycler items, adapters log says u clicked "a" but my detail fragment shows me data of "e". What I am doing wrong?

Like I said if I delete my one of recycler view its working perfect but if I use two recycler on same fragment I got wrong datas. Logs says I open correct data but it's not.
If u need my other codes to solve problem say it please I have lots of screens don't know which one I need to share to solve it.
i solved my problem but i don't know what i changed on background
i just seperate my one function to two function in MovieListesiViewmodel and gave a parameter and its worked like a miracle

Open PodcastActivity.kt and add the following lines to the top of the class. This is the question
this is the code I am adding
private val searchViewModel by viewModels()
private lateinit var podcastListAdapter: PodcastListAdapter
This is where I am adding it to
class PodcastActivity : AppCompatActivity() {
override fun onCreateOptionsMenu(menu: Menu): Boolean {
// 1
val inflater = menuInflater
inflater.inflate(R.menu.menu_search, menu)
// 2
val searchMenuItem = menu.findItem(R.id.search_item)
val searchView = searchMenuItem?.actionView as SearchView
// 3
val searchManager = getSystemService(Context.SEARCH_SERVICE)
as SearchManager
// 4
searchView.setSearchableInfo(
searchManager.getSearchableInfo(componentName)
)
return true
setupToolbar()
}
private fun performSearch(term: String) {
val itunesService = ItunesService.instance
val itunesRepo = ItunesRepo(itunesService)
itunesRepo.searchByTerm(term) {
Log.i(Companion.TAG, "Results = $it")
}
}
private fun handleIntent(intent: Intent) {
if (Intent.ACTION_SEARCH == intent.action) {
val query = intent.getStringExtra(SearchManager.QUERY) ?: return
performSearch(query)
}
}
override fun onNewIntent(intent: Intent) {
super.onNewIntent(intent)
setIntent(intent)
handleIntent(intent)
}
companion object {
private const val TAG = "PodcastActivity"
}
private fun setupToolbar() {
setSupportActionBar(toolbar)
}
}
