I am using a table layout to present data in Recycler View and data is coming from a API I have used EditText and text views in the code. I use edit text so that the user could edit that particular data and send it back to the server.
My problem is that the App crashes every time when I edit the data from the edit text and post it API.
I think the problem is with the position to get the Edittext in recycler view
Please Help me I would really glad for your your help
Thanks in advance.
here is my code
Adapter class
public class PostingAdopter extends RecyclerView.Adapter<PostingAdopter.ViewHolder> {
Context context;
List<PostingModel> postingModelList;
public PostingAdopter(Context context, List<PostingModel> postingModelList) {
this.context = context;
this.postingModelList = postingModelList;
}
@NonNull
@Override
public PostingAdopter.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.posting_item_ly,parent,false);
ViewHolder viewHolder = new ViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(@NonNull PostingAdopter.ViewHolder holder, int position) {
final PostingModel model = postingModelList.get(position);
if (postingModelList != null && postingModelList.size() > 0) {
holder.serialNo.setText(model.getSerialNo());
holder.party_name.setText(model.getPartyName());
holder.jbAmount.setText(model.getJaama_beanaam_Amount());
holder.Payment_type.setText(model.getPaymentType());
holder.remarks.setText(model.getRemarks());
holder.bill_no.setText(model.getBillno());
}
}
@Override
public int getItemCount() {
return postingModelList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
TextView serialNo,bill_no,party_name,Payment_type,remarks;
EditText jbAmount;
public ViewHolder(@NonNull View itemView) {
super(itemView);
serialNo = itemView.findViewById(R.id.serial_id_posting);
bill_no = itemView.findViewById(R.id.bill_no_posting);
party_name = itemView.findViewById(R.id.party_id_posting);
jbAmount = itemView.findViewById(R.id.jb_posting);
Payment_type = itemView.findViewById(R.id.payment_t_id);
remarks = itemView.findViewById(R.id.remark_posting);
}
}
}
Here is my ModelClass
public class PostingModel {
String SerialNo;
String jaama_beanaam_Amount;
String PartyName;
String Billno;
String PaymentType;
String Remarks;
public String getSerialNo() {
return SerialNo;
}
public void setSerialNo(String serialNo) {
SerialNo = serialNo;
}
public String getJaama_beanaam_Amount() {
return jaama_beanaam_Amount;
}
public void setJaama_beanaam_Amount(String jaama_beanaam_Amount) {
this.jaama_beanaam_Amount = jaama_beanaam_Amount;
}
public String getPartyName() {
return PartyName;
}
public void setPartyName(String partyName) {
PartyName = partyName;
}
public String getBillno() {
return Billno;
}
public void setBillno(String billno) {
Billno = billno;
}
public String getPaymentType() {
return PaymentType;
}
public void setPaymentType(String paymentType) {
PaymentType = paymentType;
}
public String getRemarks() {
return Remarks;
}
public void setRemarks(String remarks) {
Remarks = remarks;
}
public PostingModel() {
}
public PostingModel(String serialNo, String jaama_beanaam_Amount, String partyName, String billno, String paymentType, String remarks) {
SerialNo = serialNo;
this.jaama_beanaam_Amount = jaama_beanaam_Amount;
PartyName = partyName;
Billno = billno;
PaymentType = paymentType;
Remarks = remarks;
}
}
