I try to get latitude and Longitude in Recyclerview.In Main Activity I get permission for Access Location. In Secound Activity I wrote a code for get latitude and Logitude.I need to get latitude and longitude in recycler view insted of text view ..
someone help me in this..
here is the code i have tryed it ...
SecoundActivity.kt
class SecondActivity : AppCompatActivity(), LocationListener {
private lateinit var locationManager: LocationManager
private lateinit var binding: ActivitySecondBinding
private var dataAdapter: LocationAdapter? = null
private val locationPermissionCode = 2
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivitySecondBinding.inflate(LayoutInflater.from(this))
setContentView(binding.root)
setAdapter()
binding.btnGetLocation.setOnClickListener {
getLocation()
}
}
private fun getLocation() {
locationManager = getSystemService(Context.LOCATION_SERVICE) as LocationManager
if ((ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
) {
ActivityCompat.requestPermissions(this,
arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
locationPermissionCode)
}
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5000, 5f, this)
}
val lstApplication: ArrayList<LocationEntity> = ArrayList()
override fun onLocationChanged(location: Location) {
setDataList(lstApplication)
binding.tvLocationText.text = "Latitude: " + location.latitude + ",Longitude: " + location.longitude + ",altitude:"+location.altitude
}
private fun setDataList(lstApplication: ArrayList<LocationEntity>) {
}
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<out String>,
grantResults: IntArray,
) {
if (requestCode == locationPermissionCode) {
if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "Permission Granted", Toast.LENGTH_SHORT).show()
} else {
Toast.makeText(this, "Permission Denied", Toast.LENGTH_SHORT).show()
}
}
}
private fun setAdapter() {
dataAdapter = LocationAdapter()
binding.rvRecyclerView.apply {
layoutManager = LinearLayoutManager(applicationContext)
adapter = dataAdapter
}
}
}
Here I want to get latitude and longitude in recyclerview items, Not in textview.
This is my recyclerview adapter. Here I just initialize latitude and longitude textview to get them in recyclerview
LocationAdapter.kt
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val itemsViewModel = dataList[position]
holder.tvLatitude.text = itemsViewModel.latitude.toString()
holder.tvLongitude.text = itemsViewModel.longitude.toString()
}
override fun getItemCount(): Int {
return dataList.size
}
class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var tvLatitude: TextView = itemView.findViewById(R.id.tvLatitude)
var tvLongitude: TextView = itemView.findViewById(R.id.tvLongitude)
}
}
In model class I just gave latitude and Longitude and extends double for them

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)
}
So I tried to create multi views recyclerview in kotlin, but sadly it did not work.The recyclerview does not display on the screen. It worth to mention that I tried to set the orientation as vertical in my layout files, also added all the dependencies and things needed. Can anyone please help me with that?
My MainActivity.class
#AndroidEntryPoint
class MainActivity : AppCompatActivity() {
lateinit var binding: ActivityMainBinding
lateinit var adapter: NumbersAdapter
lateinit var recyclerView: RecyclerView
var list: List<Nums> = listOf(Nums(1,false))
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
updateAll()
}
fun updateAll(){
binding.recyclerview.apply {
val layoutManager = LinearLayoutManager(this#MainActivity)
adapter = NumbersAdapter(list)
adapter = adapter
}}}
My Adapter
class NumbersAdapter(
var list: List<Nums>,
): RecyclerView.Adapter<RecyclerView.ViewHolder>() {
class RedViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
val name = itemView.findViewById<TextView>(R.id.red_number)
fun bindRed(number: Nums) {
name.text = number.nums.toString()
}
}
class OrangeViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
val name = itemView.findViewById<TextView>(R.id.orange_number)
fun bindOrange(number: Nums) {
name.text = number.nums.toString()
}
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
if (viewType == 0) {
val redvView =
LayoutInflater.from(parent.context).inflate(R.layout.red_item, parent, false)
return RedViewHolder(redvView)
}
else {
val orangeView =
LayoutInflater.from(parent.context).inflate(R.layout.orange_item, parent, false)
return OrangeViewHolder(orangeView)
}
}
override fun getItemCount(): Int {
return list.size
}
override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
if(getItemViewType(position)==0){
(holder as RedViewHolder).bindRed(list[position])
}
else{
(holder as OrangeViewHolder).bindOrange(list[position])
}
}
override fun getItemViewType(position: Int): Int {
checkItem()
if(list[position].flag)
return 0
return 1
}
fun checkItem(){
for (i in list.indices) {
for (k in i + 1 until list.size) {
if (list[i].nums + list[k].nums == 0) {
list[i].flag = true
list[k].flag = true
}}}}}
in MainActivity.class change code in updateAll() function
fun updateAll(){
binding.recyclerView.apply {
adapter = NumbersAdapter(list)
layoutManager = LinearLayoutManager(this#MainActivity)
}
}
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? Here is my codes:(I have lots of codes so I share what we need)

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

I want to know how I can receive the data from adapter (recyclerview) to DetailsActivity. I tried many times but the images from recyclerview doesn't show in DetailsActivity.
this is my code.
ImageAdapter
class ImageAdapter (private var items:List<Item>, private val context:Context):
RecyclerView.Adapter<ImageAdapter.ViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int):ViewHolder {
return ViewHolder(
LayoutInflater.from(context).inflate(R.layout.item, parent, false)
)
}
override fun getItemCount(): Int {
return items.size
}
override fun onBindViewHolder(holder: ImageAdapter.ViewHolder, position: Int) {
val item = items[position]
Picasso.get().load(item.imageUrl).into(holder.imageView)
holder.imageView.setOnClickListener {
val intent = Intent(context, DetailsActivity::class.java)
intent.putExtra("iImages", item.imageUrl)
context.startActivity(intent)
}
}
class ViewHolder(view:View):RecyclerView.ViewHolder(view) {
val imageView : ImageView = view.findViewById(R.id.imageView)
}
}
DetailsActivity
class DetailsActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_details)
val aImageView = intent.getIntExtra("iImages", 0)
details_image.setImageResource(aImageView)
}
}
RecyclerActivity
class RecyclerActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_recycler)
val storage = FirebaseStorage.getInstance()
val storageRef = storage.reference.child("wallpapers")
val imageList : ArrayList<Item> = ArrayList()
//progressBar.visibility = View.VISIBLE
val listAllTask : Task<ListResult> = storageRef.listAll()
listAllTask.addOnCompleteListener { result ->
val items: List<StorageReference> = result.result!!.items
//add cycle for add image url to list
items.forEachIndexed { index,item ->
item.downloadUrl.addOnSuccessListener {
Log.d("item", "$it")
imageList.add(Item(it.toString()))
}.addOnCompleteListener {
recyclerview.adapter = ImageAdapter(imageList, this)
recyclerview.layoutManager = LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)
//progressBar.visibility = View.GONE
}
}
}
}
}
Item
data class Item(
var imageUrl: String
)
The problem is this line:
details_image.setImageResource(aImageView)
You are setting a resource int but what you pass seems to be a url, so instead load the "iImages" value with Picasso for that view
Edit: Replace this:
val aImageView = intent.getIntExtra("iImages", 0)
details_image.setImageResource(aImageView)
with this
val retrievedImageUrl = intent.getIntExtra("iImages", 0)
Picasso.get().load(retrievedImageUrl).into(details_image)
The Answer
val imageView : ImageView = findViewById(R.id.details_image)
Glide.with(this).load(intent.getStringExtra("iImages")).into(imageView)
A very newbie programmer here and not a good English typer. Im trying to create a checker for purchase that already made previous using the PurchaseHistoryResponseListener. And When a checker found something, it will add to a list and then feed the recyclerview_MYBook with that data. The issue is that when launching the app, the data is flow through the recyclerview_MYBook perfectly, but when moving to different activity and going back to the previous activity through a different method (button click) the data on the recyclerview_MYBook doesn't show up, only through a conventional back button, the data on the recyclerview show up. Below here is my noob code
class MainActivity : AppCompatActivity(), PurchasesUpdatedListener {
private lateinit var billingClient: BillingClient
private lateinit var blogadapternew: BlogRecyclerAdapterNew
private lateinit var blogadapterpremium: BlogRecyclerAdapterPremium
private lateinit var blogadapterfree: BlogRecyclerAdapterFree

Here is adapter
class BlogRecyclerAdapterMyBook : RecyclerView.Adapter() {
private var items: List<BlogPost> = ArrayList()
private var items2: List<BlogPost> = ArrayList()
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
return BlogViewHolder(
LayoutInflater.from(parent.context).inflate(
R.layout.layout_blog_list_item_mybook,
parent,
false
)
)
}
override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
when (holder) {
is BlogViewHolder -> {
holder.bind(items.get(position))
holder.bind(items2.get(position))
}
}
}
override fun getItemCount(): Int {
return items.size
}
fun submitList(bloglist: List<BlogPost>) {
items = bloglist
items2 = bloglist
}
class BlogViewHolder constructor(itemView: View) : RecyclerView.ViewHolder(itemView) {
val blogImage: ImageButton = itemView.blog_imagemybook
val blogTitle: TextView = itemView.blog_titlemybook
val premiumImage: ImageView = itemView.premiumicon
fun bind(blogPost: BlogPost) {
blogTitle.setText(blogPost.title)
val requestOptions = RequestOptions()
.placeholder(R.drawable.mocksplash)
.error(R.drawable.disconnect)
Glide.with(itemView.blog_imagemybook)
.applyDefaultRequestOptions(requestOptions)
.load(blogPost.image)
.into(blogImage)
blogImage.setOnClickListener {
Toast.makeText(blogImage.context, "<<Swipe left<<", Toast.LENGTH_SHORT).show()
val intent = Intent(blogTitle.context, ComicReadingActivity::class.java)
var KomikName = blogTitle.text.toString()
intent.putExtra("KomikName",Name)
blogImage.context.startActivity(intent)
}
}
}
}
and here the data source file where that will store the data for the adapter
class DataSourceMyBook{
companion object{
fun createDataSet(): ArrayList<BlogPost> {
val dataMyBook1 = ArrayList<BlogPost>()
return dataMyBook1
}
}
}
