The codes written here belong to the fragment I created the profile page for.
I am trying to upload an image to Firebase Storage by clicking the button with imageUpload id. However, it is not saved to the Storage and the photo I uploaded disappears when I click on a different page.
Do I need to add the codes somewhere other than OnViewCreated?
Also, when I assign an onClick method to a button, image or something else, I cannot call it with the fun method. For example, let uploadImage be the onClick function, not the button's id. I can't define it as 'fun uploadImage' anywhere in the fragment, why?

JUST ADD THIS IN YOUR StoryViewFragment.

viewModel with two fragments is not working

I am developing an app, where users can add their address in their profile and now I want to add a viewModel observer on the coordinates I am receiving from the profile fragment, like my fragment A and give this information to a map fragment, so I can create a new marker on that location. Apparently I am not getting any information of the observer in my fragment B.
So that is my code:
This is the first fragment of the profile:
class ProfilFoto : Fragment() {
lateinit var mDatabase : DatabaseReference
var mAuth = FirebaseAuth.getInstance()
var user = FirebaseAuth.getInstance().currentUser
var DISPLAY_NAME : String? = null
private var model: Communicator?=null
#SuppressLint("SetTextI18n", "ResourceType")
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
// setContentView(R.layout.fragment_notifications)
val rootView: View = inflater.inflate(R.layout.fragment_profil_foto, container, false)
model= activity?.let { ViewModelProviders.of(it).get(Communicator::class.java) }
val loca = rootView.findViewById<View>(R.id.locationtext) as TextView
var uid = user!!.uid
val userHashMap = HashMap<String, Any>()
mDatabase = FirebaseDatabase.getInstance().getReference("User").child(uid)
val speicherButton = rootView.findViewById<Button>(R.id.speichern)
speicherButton.setOnClickListener {
val location = rootView.findViewById<View>(R.id.locationPerson) as EditText
val loc = location.text.toString()
if (!loc.isEmpty()) {
Log.e("Location", loc)
val locationAddress = GeocodingLocation()
locationAddress.getAddressFromLocation(loc,
getActivity()?.getApplicationContext(), GeocoderHandler())
model!!.setMsgCommunicator(locationAddress.toString())
//userHashMap["Adresse"] = loc
mDatabase.child("Adresse").setValue(loc)
.addOnSuccessListener {
Log.e("Telefon", loc)
}
.addOnFailureListener {
Log.e("Telefon2", "failed")
}
// mDatabase.updateChildren(userHashMap)
}
}
mDatabase.addValueEventListener(object : ValueEventListener {
override fun onCancelled(error: DatabaseError) {
TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
}
return rootView
}
private class GeocoderHandler : Handler() {
override fun handleMessage(message: Message) {
val locationAddress: String?
locationAddress = when (message.what) {
1 -> {
val bundle: Bundle = message.getData()
bundle.getString("address")
}
else -> null
}
if (locationAddress != null) {
Log.e("Handler", locationAddress)
}
}
}
}
And this is the map fragment where the message should appear:
class MapsFragment : Fragment() {
private val callback = OnMapReadyCallback { googleMap ->
val model= activity?.let { ViewModelProviders.of(it).get(Communicator::class.java) }
if (model != null) {
model.message.observe(this, { t ->
//txt.text = o!!.toString()
Log.e("Marker", t.toString())
var latlong = t.toString().split(",")
var lat = parseFloat(latlong[0])
var long = parseFloat(latlong[1])
googleMap.addMarker(
MarkerOptions()
.position(LatLng(lat.toDouble(), long.toDouble()))
.title("Der Neue")
)
})
}
}
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
val rootView : View = inflater.inflate(R.layout.fragment_maps, container, false)
...
return rootView
}
and this is the communicator class I am using:
import androidx.lifecycle.MutableLiveData
import androidx.lifecycle.ViewModel
class Communicator : ViewModel(){
val message =MutableLiveData<Any>()
fun setMsgCommunicator(msg:String){
message.setValue(msg)
}
}
and maybe it is important to also show the GeoLocator from where I am getting the coordinates:
private const val TAG = "GeocodingLocation"
public class GeocodingLocation {
lateinit var mDatabase : DatabaseReference
var user = FirebaseAuth.getInstance().currentUser
fun getAddressFromLocation(locationAddress: String,
context: Context?, handler: Handler?) {
val thread: Thread = object : Thread() {
override fun run() {
val geocoder = Geocoder(context, Locale.getDefault())
var result: String? = null
var uid = user!!.uid
mDatabase = FirebaseDatabase.getInstance().getReference("User").child(uid)
try {
val addressList: List<*>? = geocoder.getFromLocationName(locationAddress, 1)
if (addressList != null && addressList.size > 0) {
val address: Address = addressList[0] as Address
val sb = StringBuilder()
sb.append(address.getLatitude()).append("\n")
mDatabase.child("Latitude").setValue(address.latitude)
.addOnSuccessListener {
Log.e("Telefon", address.latitude.toString())
}
.addOnFailureListener {
Log.e("Telefon2", "failed")
}
sb.append(address.getLongitude()).append("\n")
mDatabase.child("Longtitude").setValue(address.longitude)
.addOnSuccessListener {
Log.e("Telefon", address.longitude.toString())
}
.addOnFailureListener {
Log.e("Telefon2", "failed")
}
result = sb.toString()
}
} catch (e: IOException) {
Log.e(TAG, "Unable to connect to Geocoder", e)
} finally {
val message: Message = Message.obtain()
message.setTarget(handler)
if (result != null) {
message.what = 1
val bundle = Bundle()
bundle.putString("address", result)
message.setData(bundle)
} else {
message.what = 1
val bundle = Bundle()
result = """Address: $locationAddress
Unable to get Latitude and Longitude for this address location."""
bundle.putString("address", result)
message.setData(bundle)
}
message.sendToTarget()
}
}
}
thread.start()
}
}
Does anybody know what I am doing wrong to get absolutely nothing? Like in the profile fragment I am receiving a latitude and longitude in the Log.

Move the registering observer code, outside the callback block. Inside the callback, set the value when map is ready to update. In the observer check if map is ready, set the marker. Hope that works!
private lateinit var googleMap: GoogleMap
private val callback = OnMapReadyCallback { map ->
googleMap = map
}
val model= activity?.let { ViewModelProviders.of(it).get(Communicator::class.java) }
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
val rootView : View = inflater.inflate(R.layout.fragment_maps, container, false)
if (model != null) {
model.message.observe(this, { t ->
//txt.text = o!!.toString()
Log.e("Marker", t.toString())
var latlong = t.toString().split(",")
var lat = parseFloat(latlong[0])
var long = parseFloat(latlong[1])
googleMap?.let{
it.addMarker(
MarkerOptions()
.position(LatLng(lat.toDouble(), long.toDouble()))
.title("Der Neue")
)
})
}
}
return rootView
}

How can I call a variab that I wrote in a non-Class place to another class?

1.The "address" variable here gives me a city name with coordinates.I would like to write this address instead of Istanbul in the retrofit so that it can automatically show the weather of the selected location on the map.(Googlemap)
private const val TAG = "MapViewFragment"
class MapViewFragment: Fragment(), OnMapReadyCallback {
companion object{
private lateinit var nMap: GoogleMap
var address:String = ""
var test:String = ""
var test2:String = ""
var cacik:String = "adana"
private var markers:MutableList<Marker> = mutableListOf<Marker>()
}
override fun onActivityCreated(savedInstanceState: Bundle?) {
super.onActivityCreated(savedInstanceState)
map_view.onCreate(savedInstanceState)
map_view.onResume()
map_view.getMapAsync(this)
setToolbar()
}
override fun onMapReady(map: GoogleMap?) {
if (map != null) {
nMap = map
}
map?.let {
nMap = it
nMap.setOnInfoWindowClickListener { markerToDelete ->
Log.i(TAG, "onWindowsClickListener - Delete Thismarker")
markers.remove(markerToDelete)
markerToDelete.remove()
}
nMap.setOnMapLongClickListener { latlng ->
Log.i(TAG, "onMapLongClickListener" + latlng)
Toast.makeText(
requireContext(),
"this is toast message" + latlng,
Toast.LENGTH_SHORT
).show()
showAlertDialog(latlng)
address= getAddress(latlng.latitude, latlng.longitude)
test = getAddress(37.000000,35.321335)
test2 = "istanbul"
Log.d(TAG,"test5 $address ${latlng.latitude} ${latlng.longitude}")
Toast.makeText(requireContext(),"test"+address,Toast.LENGTH_LONG).show()
}
}
}
private fun getAddress(lat: Double, lng: Double): String {
val geocoder = Geocoder(requireContext())
val list = geocoder.getFromLocation(lat, lng, 1)
return list[0].getAddressLine(0)
//val stateName: String = addresses[0].getAddressLine(1)
}
private fun showAlertDialog(latlng: LatLng) {
val dialog =
AlertDialog.Builder(requireContext())
.setTitle("Create a marker").setMessage("add marker...")
.setNegativeButton("Cancel", null)
.setPositiveButton("Ok", null)
.show()
dialog.getButton(DialogInterface.BUTTON_POSITIVE).setOnClickListener {
val marker = nMap.addMarker(
MarkerOptions().position(latlng).title("my new marker").snippet(
"a cool snippet"
)
)
markers.add(marker)
dialog.dismiss()
}
dialog.getButton(DialogInterface.BUTTON_NEGATIVE).setOnClickListener {
dialog.dismiss()
}
}
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.mapviewfragment, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
}
private fun setToolbar(){
val actionBar : ActionBar? =(requireActivity() as MainActivity).supportActionBar
actionBar?.apply {
title = getString(R.string.Kartenansicht)
setDisplayShowTitleEnabled(true)
setHomeButtonEnabled(true)
}
}
}
3.i just want to call "address" in my retrofit response .I want to call the address on the other class and write the location of Istanbul.The getter and setter methods don't work because I haven't written them inside the class.How can I use the address in another class.
private const val TAG = "Retrofit Connection"
fun main(){
retrofitResponse()
}
object RetrofitSetup {
//var test = MapViewFragment.address
var urlAll = "api.openweathermap.org/data/2.5/weather?q={city name}&appid={API key}"
var url = "https://api.openweathermap.org/data/2.5/"
val apiKey = "d459f98ffa705ad3f6c5e02f86d9fab9"
}
fun retrofitResponse(){
val retrofit = Retrofit.Builder()
.baseUrl(RetrofitSetup.url)
.addConverterFactory(GsonConverterFactory.create())
.build()
val weatherApi = retrofit.create(CallWeatherApi::class.java)
val weatherResponseCall = weatherApi.getWeather(MapViewFragment.test,RetrofitSetup.apiKey)
weatherResponseCall!!.enqueue(object : Callback<CurrentWeatherResponse?> {
override fun onResponse(call: Call<CurrentWeatherResponse?>, response: Response<CurrentWeatherResponse?>
) {
if (response.code() == 404) {
Log.d(TAG,"Successfuly")
} else if (!response.isSuccessful) {
Log.d(TAG,"Error")
}
val mydata = response.body()
val main = mydata!!.main
val temp = main!!.temp
val pres =main!!.pressure
val temperature = (temp!! - 273.15).toInt()
Log.d("TAG","City pressure :" + pres)
Log.d("TAG","City Temp : " + temperature)
}
override fun onFailure(call: Call<CurrentWeatherResponse?>, t: Throwable) {}
})
}
if i write default istanbul.its working
if i create another varible in other class dosent work
exception

put "retrofitResponse" inside "RetrofitSetup" and add a parameter for the addresss
object RetrofitSetup {
private const val urlAll = "api.openweathermap.org/data/2.5/weather?q={city name}&appid={API key}"
private const val url = "https://api.openweathermap.org/data/2.5/"
private const val apiKey = "keep this private"
fun retrofitResponse(address: String) {
...
val weatherResponseCall = weatherApi.getWeather(address, apiKey)
...
}
}
then pass the address as argument
nMap.setOnMapLongClickListener { latlng ->
val address = getAddress(latlng.latitude, latlng.longitude)
RetrofitSetup.retrofitResponse(address)
}

This is my firebase helper:
class FirebaseHelper(val db: DatabaseReference) {
private var saved: Boolean? = null
//SAVE
fun save(bankData: BankData?): Boolean? {
saved = if (bankData == null) {
false
} else {
try {
db.child("name").push().setValue(bankData)
true
} catch (e: DatabaseException) {
e.printStackTrace()
false
}
}
return saved
}
//READ
fun retrieve(): ArrayList<String> {
val bankNames = ArrayList<String>()
db.addChildEventListener(object : ChildEventListener {
override fun onChildAdded(
dataSnapshot: DataSnapshot,
s: String?
) {
fetchData(dataSnapshot, bankNames)
}
override fun onChildChanged(
dataSnapshot: DataSnapshot,
s: String?
) {
fetchData(dataSnapshot, bankNames)
}
override fun onChildRemoved(dataSnapshot: DataSnapshot) {}
override fun onChildMoved(
dataSnapshot: DataSnapshot,
s: String?
) {
}
override fun onCancelled(databaseError: DatabaseError) {}
})
return bankNames
}
private fun fetchData(
snapshot: DataSnapshot,
bankData: ArrayList<String>
) {
bankData.clear()
val name: BankData? = snapshot.getValue(BankData::class.java)
bankData.add(bankData.toString())
}
}

Your spinner shows no value because the data is not retrieved yet from the DB.
So what you should do is create a callback from FirebaseHelper to IncomeFragment
First, create a callback
interface FirebaseHelperCallback {
fun dataRetrievedFromDB(data: List<String>)
}
Second, create a variable, setter function and call dataRetrievedFromDB function in FirebaseHelper class
class FirebaseHelper(val db: DatabaseReference) {
private lateinit var firebaseHelperCallback: FirebaseHelperCallback
fun setFirebaseHelperCallback(firebaseHelperCallback: FirebaseHelperCallback) {
this.firebaseHelperCallback = firebaseHelperCallback
}
...
private fun fetchData(snapshot: DataSnapshot, bankData: ArrayList<String>) {
bankData.clear()
val name: BankData? = snapshot.getValue(BankData::class.java)
bankData.add(bankData.toString())
firebaseHelperCallback.dataRetrievedFromDB(bankData)
}
}
Lastly, implement the callback in IncomeFragment
class IncomeFragment: Fragment(), FirebaseHelperCallback {
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
...
helper.setFirebaseHelperCallback(this)
}
...
override fun dataRetrievedFromDB(data: List<String>) {
spinner.setAdapter(
activity?.let {
ArrayAdapter<String>(
it,
android.R.layout.simple_list_item_1,
data
)
}
)
}
}
