I am having a hard time figuring out how I can connect my Repository
and ViewModel
's live data in-case of @GET
request and observe them in the fragment.
I don't have this problem when the request type is @POST
because I can use Transformation.switchMap
on the body and whenever the body changes repository's function gets invoked and emits value to the response live data something like this
val matchSetsDetail: LiveData<Resource<MatchDetailBean>> = Transformations.switchMap(matchIdLiveData) { matchId ->
val body = MatchSetRequest(matchId)
repository.getMatchSet(body)
}
but in case of @GET
request, I have several query parameter that my View supplies
I have this retrofit API call in repository class and the code looks like this
class Repository {
fun checkInCheckOutUser(apiKey: String, userId: Int, status: String, latitude: Double, longitude: Double, checkedOn: Long): LiveData<Resource<BaseResponse>> = liveData {
emit(Resource.Loading())
try {
val response: Response<BaseResponse> = ApiClient.coachApi.checkInCheckOutUser(apiKey, userId, status, latitude, longitude, checkedOn)
if (response.isSuccessful && response.body() != null) {
if (response.body()!!.isValidKey && response.body()!!.success) {
emit(Resource.Success(response.body()!!))
} else {
emit(Resource.Failure(response.body()!!.message))
}
} else {
emit(Resource.Failure())
}
} catch (e: Exception) {
emit(Resource.Failure())
}
}
}
and ViewModel
class CheckInMapViewModel : ViewModel() {
val checkInResponse: LiveData<Resource<BaseResponse>> = MutableLiveData()
fun checkInCheckOut(apiKey: String, userId: Int, status: String, latitude: Double, longitude: Double, checkedOn: Long): LiveData<Resource<BaseResponse>> {
return repository.checkInCheckOutUser(apiKey,userId,status,latitude,longitude,checkedOn)
}
}
The main problem is I want to observe checkInResponse
the same way I am observing in case of @POST
request but don't know how to pass observe repository LiveData as I did with my post request above using Transformations.switchMap
. Can anyone help me with this case?
Edit - Here is my retrofit service class as asked
interface CoachApi {
@POST(Urls.CHECK_IN_CHECK_OUT_URL)
suspend fun checkInCheckOutUser(
@Query("apiKey") apiKey: String,
@Query("userId") userId: Int,
@Query("status") status: String,
@Query("latitude") latitude: Double,
@Query("longitude") longitude: Double,
@Query("checkedOn") checkedOn: Long
): Response<SelfCheckResponse>
@POST(Urls.SELF_CHECK_STATUS)
suspend fun getCheckInStatus(
@Query("apiKey") apiKey: String,
@Query("userId") userId: Int
): Response<SelfCheckStatusResponse>
}
