RecyclerView is duplicating Alert Dialog results

I have a fragment that is suppose to display the results of my alert dialog in my RecyclerView. Every time I click the "ADD" in my dialog, it adds duplicated results to my RecyclerView. I've searched and searched but cannot seem to find what I am doing wrong. I've tried adding .clear(); but if I add that, nothing shows up in my RecyclerView at all. I've added in my adapter getItemId and getItemViewType to return position; but the items still get duplicated. I've added adapter.setData(model) followed by adapter.notifyDataSetChange(); and my RecyclerView still shows duplicated items. The app runs so I have no logcat to post. Thank you.

In OnAddSubjectSubmit() you call subMod.add(model);
and then you call recyclerSubAdapter.setData(subMod); which in turn calls this.subMod.addAll(data);.
Check it yourself. I believe it's there where you add the new item twice.
Suggestion: comment out recyclerSubAdapter.setData(subMod); from OnAddSubjectSubmit().

this.subMod = data;
this.subMod.addAll(data);
You initilize subMod by assigning data to it, and later you add data again:
this.subMod.addAll(data);

I have been making an app that uses a RecyclerView but its not showing any thing..why contents of the recycler view have not been showing up.my codes are bellow

public class HistoryObject {

public HistoryObject(String rideId) {
this.rideId = rideId;

public String getRideId() {
return rideId;

public void setRideId(String rideId) {
this.rideId = rideId;
}
}
HistoryViewHolders.java
public class HistoryViewHolders extends RecyclerView.ViewHolder implements View.OnClickListener{

itemView.setOnClickListener(this);

#Override

You're returning zero for the itemCount, therefore your adapter thinks you don't have any items. Try this in your adapter:
#Override
public int getItemCount() {
return itemList.size();
}

Whatsapp like image choose and add caption

I wants to develop app in which user could choose multiple photos from gallery and can add caption like there is in whatsapp to add captions in multiple images
Anyone can help me in this.

RecyclerView Item Click Listener with DataBinding

I have implemented recycler view with data binding using a baseadapter which handles all the binding of any layout item.
I have tried to implement per item click listener using method reference and Listener bindings, but I couldn't do that.
Here is my code. Can you give me a sample which is the simple way to detect every single item of the recycler view and I want to add click listener for every single item for different purposes. Thanks.
MyBaseAdapter
public abstract class MyBaseAdapter extends RecyclerView.Adapter<MyBaseAdapter.MyViewHold> {
public class MyViewHold extends RecyclerView.ViewHolder implements View.OnClickListener {
public ViewDataBinding binding;
Context context;
public MyViewHold(ViewDataBinding binding) {
super(binding.getRoot());
this.binding = binding;
context = binding.getRoot().getContext();
binding.getRoot().setOnClickListener(this);
}
// Here BR.pojo must be matched to layout variable name
//our layout variable was
/*
<variable
name="pojo"
type="com.durbinlabs.databinding.POJO"
/>
*/
public void bind(Object obj) {
binding.setVariable(BR.pojo, obj);
binding.setVariable(BR.food, obj);
binding.executePendingBindings();
}
#Override
public void onClick(View view) {
// for all view
}
}
#Override
public MyViewHold onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater layoutInflater = LayoutInflater.from(parent.getContext());
ViewDataBinding binding = DataBindingUtil.inflate(layoutInflater, getLayoutIdForType(viewType)
, parent, false);
return new MyBaseAdapter.MyViewHold(binding);
}
#Override
public void onBindViewHolder(MyViewHold holder, int position) {
holder.bind(getDataAtPosition(position));
Log.d("click", "" + holder.getItemId());
}
public abstract Object getDataAtPosition(int position);
public abstract int getLayoutIdForType(int viewType);}
my pojo class
public class POJO extends BaseObservable {
int img;
String name;
public POJO(int img) {
this.img = img;
}
public void setImg(int img) {
this.img = img;
}
public int getImg() {
return img;
}
public POJO(int img, String name) {

recycler view row layout (per item)

Adapter
public class Adapter extends MyBaseAdapter {
private List<POJO> itemList;
Context context;
public Adapter(List<POJO> itemList) {
this.itemList = itemList;
}
public Adapter(List<POJO> itemList, Context context) {
this.itemList = itemList;
this.context = context;

#Override

return itemList.get(position);
}
#Override
public int getLayoutIdForType(int viewType) {
return R.layout.rowlayout;
}
#Override

Try this in your adapter class not base adapter
holder.binding.getRoot().findViewById(R.id.icon).setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context, "clicked", Toast.LENGTH_SHORT).show();
}
}

How save the state of RecyclerView row item?

I have a recyclerview which populates data from SQL database. Now each row in the recyclerview has a seekbar which when moved displays it's progress in a textview inside the same row. The problem is when I scroll the recyclerview up or down then return back to the first changed row, the seekbar is returned to its default position. How can I make it save the new position ? In normal activities/fragments I use lifecycle methods as "onPause" to save/restore the state. Here we have onAttachedToRecyclerView, I think it should solve my problem but I don't know exactly how.
EDIT : here is a full simple app files which I'm working on to test this problem.

If you are using recyclerview you need to maintain states of each row, means if you are checking using a condition(i.e. if) at any stage of recyclerview item(in recyclerview adapter class) then you need to handle else as well. I can send you a code snippet so you can have a good idea for recyclerview adapter.
public class ContactsAdapter extends RecyclerView.Adapter<ContactsAdapter.ViewHolder> {
List<ViewHolder> holders = new ArrayList<ViewHolder>();
private ArrayList<ContactModel> arrayList = new ArrayList<>();
private Context context;
private LayoutInflater inflater;
public void clearAdapter() {
arrayList.clear();
notifyDataSetChanged();
}
public ContactsAdapter(Context context, ArrayList<ContactModel> arrayList) {
this.context = context;
this.arrayList = arrayList;
}
public void setList(ArrayList<ContactModel> listSearch) {
this.arrayList = listSearch;
notifyItemRangeChanged(0, listSearch.size());
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
inflater = LayoutInflater.from(parent.getContext());
View view = inflater.inflate(R.layout.custom_row_for_contacts, parent, false);
ViewHolder viewHolder = new ViewHolder(view);
holders.add(viewHolder);
return viewHolder;
}
#Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
final ContactModel current = this.arrayList.get(position);
holder.txtDriverName.setText(current.getName());
holder.txtDriverPhone.setText(current.getPhone());
if (current.getImgUrl().length() > 0) {
String urlLicenceThumb = UrlEndPoints.parentUrl + current.getImgUrl();
Glide.with(context).load(urlLicenceThumb).error(R.mipmap.ic_launcher).into(holder.imgDriver);
} else {
Glide.with(context).load(R.mipmap.ic_launcher).into(holder.imgDriver);
}
}
public void delete(int position) {
arrayList.remove(position);
notifyItemRemoved(position);
}
#Override
public int getItemCount() {
return (null != arrayList ? arrayList.size() : 0);
}
class ViewHolder extends RecyclerView.ViewHolder {
private TextView txtDriverName, txtDriverPhone;
private CircleImageView imgDriver;
private Button btnInvite;
private CheckBox chkAdd;
public ViewHolder(View itemView) {
super(itemView);
chkAdd = (CheckBox) itemView.findViewById(R.id.chkAdd);
imgDriver = (CircleImageView) itemView.findViewById(R.id.imgDriver);
txtDriverName = (TextView)itemView.findViewById(R.id.txtDriverName);
txtDriverPhone = (TextView) itemView.findViewById(R.id.txtDriverPhone);
btnInvite = (Button) itemView.findViewById(R.id.btnInvite);
}
}
}
