当参数传递给接口(interface)时,Json Server数据在Android中使用Retrofit2和rxjava2显示,然后给出错误。
class Sales : AppCompatActivity() {
internal lateinit var api : APIInterface
private var compositeDisposable : CompositeDisposable? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_sales)
compositeDisposable = CompositeDisposable()
fetchYearData()
}
private fun fetchYearData(){
val retrofit = APIClient.apIClient
if (retrofit != null) {
api = retrofit.create(APIInterface::class.java)
}
compositeDisposable!!.add(api.getSalesGSTData(1,1,"04/01/2018","31/03/2019")
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe( { displaySalesGSTData(it.salesGST) },
{
Toast.makeText(this,it.message,Toast.LENGTH_LONG).show()
}))
}
成功后以及在JSONArray和JSONObject之后,模型类SalesGSTList JsonObject。
SalesGSTList.kt
class SalesGSTList {
val success : String = ""
lateinit var salesGST : ArrayList<SalesGST>
}
SalesGST.kt
class SalesGST {
var FYearID : Int = 0
var Cmp_Name : String? = ""
var GSTIN : String? = ""
}
接口(interface)
@GET("SalesGST.php")
fun getSalesGSTData(@Query("cid") cid : Int,@Query("fid") fid : Int,@Query("fd") fd : String,@Query("td") td : String) : Observable<SalesGSTList>
最佳答案
只需从lateinit
中的lateinit var salesGST : ArrayList<SalesGST>
行中删除SalesGSTList
即可。
class SalesGSTList {
val success : String = ""
var salesGST : ArrayList<SalesGST>? = null
// you can also use
// var salesGST : ArrayList<SalesGST> = ArrayList()
}
