I want to update firestore data which I have got in a Recycler view.
Recycler View Activity Code
class AdminActivity : AppCompatActivity() {
private val dB = Firebase.firestore
private lateinit var userRecyclerView: RecyclerView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
supportActionBar?.title = "Admin Panel"
userRecyclerView = findViewById(R.id.user_list)
userRecyclerView.layoutManager = LinearLayoutManager(this)
userRecyclerView.setHasFixedSize(true)
val query = dB.collection("users")
val options = FirestoreRecyclerOptions.Builder<User>().setQuery(query, User::class.java)
.setLifecycleOwner(this).build()
//adapter
val adapter = object : FirestoreRecyclerAdapter<User, UserViewHolder>(options) {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): UserViewHolder {
val view = LayoutInflater.from(this#AdminActivity)
.inflate(R.layout.user_item, parent, false)
return UserViewHolder(view)
}
override fun onBindViewHolder(holder: UserViewHolder, position: Int, model: User) {
val nameTv: TextView = holder.itemView.findViewById(R.id.name_textview)
val idTv: TextView = holder.itemView.findViewById(R.id.id_textview)
val phoneTv: TextView = holder.itemView.findViewById(R.id.phone_textview)
nameTv.text = model.name
idTv.text = model.id
phoneTv.text = model.phone
holder.itemView.setOnClickListener {
val intent = Intent(baseContext, AdminViewActivity::class.java)
startActivity(intent)
}
}
}
userRecyclerView.adapter = adapter
}
}
I want to update the data when i click on the holder.
Only update the data of the user whose recycler view I clicked.
Firestore Database Image
so, i have a little problem here. in my Main Activity (CovidActivity) i want to show only "key" on my Adapter and then in my Second Activity (DetailCovidActivity) i want to show "kasus","sembuh","meninggal",and "dirawat". how to do that?
this is my CovidActivity
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityCovidBinding.inflate(layoutInflater)
setContentView(binding.root)
adapterCovid = CovidAdapter(
listener = object: CovidAdapter.EventListener{
override fun onClick(itemList: CovidProvinceResponse.ListData) {
startActivity(
Intent(this#CovidActivity, DetailCovidActivity::class.java)
.putExtra("key",itemList.key)
.putExtra("kasus",itemList.jumlahKasus)
.putExtra("sembuh",itemList.jumlahSembuh)
.putExtra("meninggal",itemList.jumlahMeninggal)
.putExtra("dirawat",itemList.jumlahDirawat)
)
}
},listCovid = emptyList()
)
binding.rvShowCovid.adapter = adapterCovid
bindViewModel()
viewModel.getCovidProvince()
}
this is the onBindViewHolder in my Adapter
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val itemList = listCovid[position]
holder.binding.tvDaerah.text = itemList.key
holder.binding.tvJumlahKasus.text = itemList.jumlahKasus.toString()
holder.binding.tvJumlahSembuh.text = itemList.jumlahSembuh.toString()
holder.binding.tvJumlahMeninggal.text = itemList.jumlahMeninggal.toString()
holder.binding.tvJumlahDirawat.text = itemList.jumlahDirawat.toString()
holder.itemView.setOnClickListener {
listener.onClick(itemList)
}
}
and then this is the Second Activity (DetailCovidActivity)
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityDetailCovidBinding.inflate(layoutInflater)
setContentView(binding.root)
val province = intent.getStringExtra("key")
val kasus = intent.getIntExtra("kasus",0)
val sembuh = intent.getIntExtra("sembuh",0)
val meninggal = intent.getIntExtra("meninggal",0)
val dirawat = intent.getIntExtra("dirawat",0)
binding.tvDetailDaerah.text = province
binding.tvDetailKasus.text = kasus.toString()
binding.tvDetailSembuh.text = sembuh.toString()
binding.tvDetailMeninggal.text = meninggal.toString()
binding.tvDetailDirawat.text = dirawat.toString()
}
I have added the bottom sheet dialog on a fragment.
Right now I can't open it.
Whenever I click on the show button it doesn't work at all.
How can I fix this problem?
CreateFragment.kt
class CreateFragment : Fragment() {
lateinit var binding: FragmentCreateBinding;
val viewModel: NotesViewModel by viewModels()
private var color = -1
private val currentDate = SimpleDateFormat.getInstance().format(Date())
private lateinit var result: String
private val job = CoroutineScope(Dispatchers.Main)
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
binding = FragmentCreateBinding.inflate(layoutInflater, container, false)
val animation = MaterialContainerTransform().apply {
drawingViewId = R.id.createFragment
scrimColor = Color.TRANSPARENT
duration = 300L
}
binding.backbutton.setOnClickListener {
requireView().hideKeyboard()
Navigation.findNavController(it).popBackStack()
}
sharedElementEnterTransition = animation
sharedElementReturnTransition = animation
binding.fabcolorpick.setOnClickListener {
val bottomSheetDialog = BottomSheetDialog(
requireContext(),
R.style.BottomSheetDialogTheme
)
val bottomSheetView: View = layoutInflater.inflate(
R.layout.bottomsheetlayout,
null,
)
val bottomSheetBinding = BottomsheetlayoutBinding.bind(bottomSheetView)
bottomSheetBinding.apply {
colorpicker.apply {
setSelectedColor(color)
setOnColorSelectedListener { value ->
color = value
binding.apply {
createFragmentxmlid.setBackgroundColor(color)
toolbarfragmentnotecontent.setBackgroundColor(color)
bottombar.setBackgroundColor(color)
activity?.window?.statusBarColor = color
}
bottomSheetBinding.bottomSheetparent.setCardBackgroundColor(color)
}
}
bottomSheetparent.setCardBackgroundColor(color)
}
bottomSheetView.post {
bottomSheetDialog.behavior.state = BottomSheetBehavior.STATE_EXPANDED
}
}
binding.btndonenotes.setOnClickListener {
createNotes(it)
}
try {
binding.edittextnote.setOnFocusChangeListener { _, hasFocus ->
if (hasFocus) {
binding.bottombar.visibility = View.VISIBLE
binding.edittextnote.setStylesBar(binding.styleBar)
} else {
binding.bottombar.visibility = View.GONE
}
}
} catch (e: Throwable) {
Log.d("TAG", e.stackTraceToString())
}
return binding.root
}
this is how I would do it
create the view
set view as content of dialog
call the dialog's show() method to show it or dismiss() method to dismiss it
// the content view
val bottomSheetView: View = layoutInflater.inflate(
R.layout.bottomsheetlayout,
null,
)
// and the dialog
val bottomSheetDialog = BottomSheetDialog( requireContext(),R.style.BottomSheetDialogTheme).apply{
setContent(bottomSheetView)
// or if I am using viewBinding
setContent(bottomSheetBinding.root)
}
// then in button's onClick
button.setOnClickListener{
bottomSheetDialog.show()
}
I have an image button in my recylerview and when users click it, I want a dialog box to pop up and allow the user to edit the data in the reyclerview and save the changes.

}
Summary
When users click image button. Input dialog pops up
User must be able to edit data in recyclerview and save it.
change class like this inner class ViewHolder(val binding: ItemviewLayoutBinding), var imageListener:(position:Int)->Unit)
where you call adapter , use imageListener function. Whatever you want to do you can do it inside this function. Then call it in your adapter.
in init
editBtn.setOnClickListener {
imageListener(adapterPosition)
}
I have 2 Recyclerviews in a fragment. Each item consists of 2 textview. When clicked, i want to change the color of item background and the 2 tvs and get the listofData(position) clicked also then send these s pieces of data to an activity.
The problem is 2 rvs each have its own adapter so i can't call the activity and check if data is selected from both adapters. And when i try it from the fragment i get the adapter position right but the view colors are not being changed correctly.

Solved
For anyone interested i ended up using a very simple idea. Instead of accessing the RecyclerView selected element from outside the adapter, i did all i wanted to do inside the adapter and used 4 static variables in the Fragment. 2 booleans to check
if date and time are selected or not and 2 Strings having the date and time actually selected.
Inside the Fragment:
companion object {
#JvmStatic var isTimeSelected = false
#JvmStatic var selectedTime = ""
#JvmStatic var isDateSelected = false
#JvmStatic var selectedDate = ""
....
}
Inside the Adapter's onBindViewHolder()
holder.itemLinearLayout.setOnClickListener {
selectedDate = dates?.get(position)!!
isDateSelected = true
listener?.onDateClick(position)
selectedIndex = position
notifyDataSetChanged()
}
val ctx = holder.itemLinearLayout.context
if (selectedIndex == position) {
holder.itemLinearLayout.background = (loadDrawable(ctx, R.drawable.date_time_background_selected))
holder.dateNameTV.setTextColor(loadColor(ctx, android.R.color.white))
holder.dateNumTV.setTextColor(loadColor(ctx, android.R.color.white))
} else {
holder.itemLinearLayout.background = (loadDrawable(ctx, R.drawable.date_time_background))
holder.dateNameTV.setTextColor(loadColor(ctx, R.color.black_65))
holder.dateNumTV.setTextColor(loadColor(ctx, R.color.black_65))
}
And i made sure static variables don't have old values using this
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
isTimeSelected = false
selectedTime = ""
isDateSelected = false
selectedDate = ""
}
I know it's bad practice to put onClickListener inside onBindViewHolder but i don't konw if the static variables thing is good or bad practice. Either way it's working fine for now.
There is many ways to do this, And I recommend the first one.
Using shared ViewModels for communication between fragments in the same activity. The idea is that you will tie up the ViewModel with activity and every fragment can access this ViewModel and in this ViewModel you will have a LiveData object that holds the data and observing it from both fragments and every change in the value of LiveData will affect each fragment. Shared ViewModel
Using interfaces for communication between fragments and it's a hard thing to do these days. Basic communication between fragments
Using EventBus it's easy but not recommended while you can use ViewModel at the first solution. EventBus
Try this
TimesAdapter
class TimesAdapter(
availableTimes: List<String>
) : RecyclerView.Adapter<TimesAdapter.TimeViewHolder>() {
var availableTimes:List<String> = availableTimes
set(value) {
field = value
notifyDataSetChanged()
}
var listener:TimeSelectedListener?=null
var selectedIndex:Int = -1
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): TimeViewHolder {
return TimeViewHolder(
LayoutInflater.from(parent.context)
.inflate(R.layout.date_time_element, parent, false)
)
}
override fun getItemCount(): Int = availableTimes.count()
override fun onBindViewHolder(holder: TimeViewHolder, position: Int) {
val currentDate: String? = availableTimes[position] // i.e Sun 23/5
val parts = currentDate?.split(" ")
try {
val part1 = parts?.get(0)
val part2 = parts?.get(1)
holder.dateNameTV.text = part2
holder.dateNumTV.text = part1
} catch (e: IndexOutOfBoundsException) {
e.printStackTrace()
}
holder.itemLinearLayout.setOnClickListener {
listener?.onTimeClick(position)
selectedIndex = position
}
if (selectedIndex == position) {
// Selection Code
} else {
// De selection code
}
}
class TimeViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var dateNameTV: TextView = itemView.findViewById(R.id.dateNameTV)
var dateNumTV: TextView = itemView.findViewById(R.id.dateNumTV)
var itemLinearLayout: LinearLayout = itemView.findViewById(R.id.item_linear_layout)
}
interface TimeSelectedListener {
fun onTimeClick(position: Int)
}
}
Usage from fragment
times = data.availableTimesList
timesAdapter = TimesAdapter(times).apply {
listener = object :TimesAdapter.TimeSelectedListener{
override fun onTimeClick(position: Int) {
// TODO here is where you should implement when an item is selected
}
}
}
timesRV.adapter = timesAdapter
