I'm performing a retrofit call inside an adapter..i have successfully implemented and also it is giving me the desired output but is it a good practice to perform this under adapter?????
my app is --> product selling app-->in my cart-->im displaying the product list which user wants to buy-->for this required an adapter-->there im performing a swipe to delete function -->performing retrofit call on delete(holder.delete.setonclicklistener {...}) button
my code is-->
holder.tvDelete.setOnClickListener(View.OnClickListener { view ->
progressDialog.show()
val token: String = SharedPrefManager.getInstance(context).user.access_token.toString()
RetrofitClient.instance.deletecart(token, id.toString())
.enqueue(object : Callback<DeleteResponse> {
override fun onFailure(call: Call<DeleteResponse>, t: Throwable) {
Log.d("res", "" + t)
}
override fun onResponse(
call: Call<DeleteResponse>,
response: Response<DeleteResponse>
) {
var res = response
progressDialog.dismiss()
(context as Activity).finish()
if (res.body()?.status == 200) {
Toast.makeText(
context,
res.body()?.message,
Toast.LENGTH_LONG
).show()
progress()
mItemManger.removeShownLayouts(holder.swipelayout)
notifyItemChanged(position)
notifyItemRemoved(position)
dataList?.removeAt(position)
notifyItemRangeChanged(position, dataList?.size!!)
mItemManger.closeAllItems()
} else {
try {
val jObjError =
JSONObject(response.errorBody()!!.string())
Toast.makeText(
context,
jObjError.getString("message") + jObjError.getString("user_msg"),
Toast.LENGTH_LONG
).show()
} catch (e: Exception) {
Toast.makeText(context, e.message, Toast.LENGTH_LONG).show()
Log.e("errorrr", e.message)
}
}
}
})
mItemManger.bindView(holder.itemView, position)
})
the above code is working
i have also gone through this --> passing data from on click function of my recycler adaptor
this link i performed but in activity i wont be getting access to this code in activity
mItemManger.removeShownLayouts(holder.swipelayout)
notifyItemChanged(position)
notifyItemRemoved(position)
dataList?.removeAt(position)
notifyItemRangeChanged(position, dataList?.size!!)
mItemManger.closeAllItems()
need clarification on this
need help thanks
Edit:-- i followed the above link here is my code
